I didn't report to the talent center after graduation
in addition, what I said upstairs is wrong. I have not been dispatched (I have not signed three parties) for two years, and I can be dispatched at any time ring this period
however, once you have been dispatched (signed by three parties, such as you signed with the talent center), you can be reassigned once within one year after graation, that is to say, you can only reassign within one year, and you can't reassign within one or two years. You can only print the registration certificate of the talent exchange center. After two years, you can't print the registration card at all.
There is a saying in the instry that the more formal it is, the more low-key it is. This is probably true. As you can see, the top old brokers in the foreign exchange instry seldom do marketing. If we do not do foreign exchange, we may not see their shadow in the market. The reason why they are so powerful is that they rely on the powerful power of the brand to bring public praise
In fact, it is very simple for foreign exchange companies to identify the capital market. The capital market basically has these characteristics: < UL >registered in foreign countries, especially in Southeast Asia

according to the current data, the oldest deposits in China are Xingshan, naoyumen, Huangyu and other small and medium-sized (or ore spot) banded iron ore deposits in the paleoarchean caozhuangyan formation in Qian'an City, Eastern Hebei Province. Among them, Xingshan iron deposit is a large-scale medium-sized deposit (51.46 million tons of iron ore reserves). The banded iron formation iron ore bed often occurs together with plagioclase amphibolite, chromite quartzite, sillimanite plagioclase gneiss and felsic. The metamorphism is from high amphibolite facies to granulite facies. The protolith formation is calcsilicate basic argillaceous siliceous iron sedimentary formation, which is often distributed in early tonalite and Neoarchean granodiorite and granite with inclusions of different sizes, The distribution is sporadic (see Figure 1-11). The main minerals are magnetite, quartz and mafic amphibole, and the minor minerals are actinolite, hornblende and magnetite δ< Sup > 18 < / sup > O ‰ changed from 5.08 to 6.50 (Qian Xianglin et al., 1985). The SM nd isochron age of amphibolite associated with banded iron formation is 3500ma (Jahn b.m.et al., 1987), and the zircon U-Pb age of chromite quartzite is more than 3600ma. Therefore, the age of Huangyu and Xingshan iron deposits is more than or equal to 3500ma. They are not only the oldest deposits in China, but also the oldest ones in the world. It was formed in a relatively stable volcanic sedimentary basin on the continental margin
Large scale mineralization of Precambrian deposits in China. According to this standard, the first large-scale mineralization in China occurred in the middle Archean (3.2-2.8 GA), but the ore type is single, only iron ore, and it is a banded iron building type iron deposit. During this period, a number of iron deposits were formed in Eastern Hebei, Miyun, Northern Liaoning, Fuping, Inner Mongolia and other places, such as Shuichang, mengjiagou, gongdianzi, Dashihe deposits in Qian'an, Eastern Hebei; Fengjiayu, mibei, Minan, Shachang, mazuan deposits in Miyun, Beijing; Luobukan, xiaolaihe and aoniu deposits in northern Liaoning Province; Sengguan, huangshikou and Dongzhuang deposits in Fuping, Western Hebei Province; Haolaigou deposit in Inner Mongolia. However, except that Shuichang iron deposit in Eastern Hebei is a super large deposit (902 million tons) and Fengjiayu, mibei and Minan iron deposits in Qian'an Dashihe and Miyun in Eastern Hebei are super large deposits, most of them are small and medium-sized deposits or even ore occurrences. The strata of this kind of iron deposits are Qianxi group, Hunnan group, Miyun group and Fuping group. Taking Qian'an iron ore area in Eastern Hebei Province as an example, banded iron formations often form interbedding zones with lherzolite plagioclase granulite, garnet biotite perilla plagioclase gneiss and other rocks. There are sillimanite garnet plagioclase gneiss and cordierite garnet plagioclase gneiss in the upper part of the iron deposit, which are rich in aluminum. The orebodies or ore beds are often intersected and metasomatized by the late Archean tTG series, granite and pegmatite, and even become resial bodies. Its protolith formation consists of basic volcanic rock intermediate acid greywacke argillaceous ferrosiliceous sedimentary formation. Iron ore is lean, medium coarse texture, striped banded banded gneissic texture, mineral composition is magnetite, quartz, perilla pyroxene, diopside, secondary minerals are amphibole, biotite, garnet and so on. The ore bodies are bedded, stratoid and large structural lenses, often forming syncline folds. This kind of iron deposit was formed in the volcanic sedimentary basin of continental margin, in the middle shallow to semi deep water environment, and it is a distant volcanic deposit P>(1) Neoarchean
Archean (2800 ~ 2500Ma) is a very important large-scale metallogenic period in Chinese mainland. During this period, not only did a lot of iron deposits be deposited, but also some large, extra large and super large graphite deposits, gold deposits and copper zinc deposits were formed. Neoarchean is the main formation period of greenstone belt in China. Most of the underground deposits in Anshan Benxi, Liaoning, Luanxian and Zunhua, Eastern Hebei, Taishan, Shandong, Dengfeng, Henan and Wutaishan, Shanxi are related to greenstone belt. During this period, the reserves of iron ore formed account for about 50% of the total reserves of iron ore in China, and super large iron ore deposits such as xi'anshan (iron ore reserves 1.728 billion tons, the following figures are iron ore reserves), Qidashan (1.64 billion tons), Nanfen (1.289 billion tons), DONG'ANSHAN (1.206 billion tons), hujiamiaozi (1.113 billion tons), Gongchangling (869 million tons) were formed; Sijiaying (838 million tons) super large iron deposit in Eastern Hebei Province; Shanxi goat Ping (731 million tons) super large iron deposit; Shandong Dongping (530 million tons) super large iron deposit and a large number of Liaoning Waitoushan, Jilin Banshigou, Hebei dajiazhuang, Shanxi Baiyan, Henan Xuchang and other large and super large iron deposits. Most of these deposits occur in Neoarchean greenstone belt, and iron deposits are closely related to submarine volcanic activities in space and time. Generally, the more intense the volcanic activity is and the longer it lasts, the more iron will be proced. After strong volcanic activity, if there is a relatively stable and long-term volcanic intermission, it is an important condition for the formation of large deposits. For example, the banded iron formation of Nanfen, Waitoushan and Gongchangling iron deposits in Liaoning Province is often interbedded with plagioclase amphibolite, fine-grained biotite granulite, garnet chlorite schist and mica quartz schist. Its protolith is basic intermediate acid volcanic rock muddy sandy siliceous volcanic sedimentary formation. Its metamorphic facies is high greenschist low amphibolite facies, and its iron mineral is mainly magnetite. The lower part of the banded iron formation of the Donganshan and Xishan iron deposits in Liaoning Province is the greyish green phyllite section, which is mainly composed of chlorite phyllite and sericite chlorite phyllite; The upper part is gray phyllite section, and the lithology is mainly sericite phyllite, chlorite phyllite, biotite quartz phyllite and granulite. The protolith formation consists of basic volcanic rock argillaceous intermediate acid greywacke siliceous iron formation. The iron deposits such as yangyangping and jiyan in Shanxi Province are closely related to basic volcanic rocks (the rock types are sericite chlorite schist, black hard chlorite schist, hornblende schist, etc.). In a word, this kind of iron deposit can be compared with argoma type iron deposit in greenstone belt. Large scale gold mineralization also occurred in the Neoarchean. Gold deposits were mainly formed in the late Neoarchean or Neoarchean Paleoproterozoic, closely related to the greenstone belt. The relatively large-scale gold deposits are Jinchangyu super large gold deposit in Qianxi, Hebei Province (reserves 59.53 tons), sanchuo medium gold deposit (reserves 14.86 tons), Banmiaozi medium gold deposit (reserves 14.28 tons) and Ergou medium gold deposit (reserves 13.1 tons) in the concentrated area of Jiapigou gold deposit in Huadian, Jilin Province. The host rock of the gold deposit is mylonite formed by amphibolite and amphibolite plagiogneiss under ctile shear, which is quartz vein type. The gold ore is mainly natural gold, and often occurs together with pyrite. The zircon tims age of gold bearing quartz vein in Jinchangyu Gold Deposit is 2539 ± 23ma (Li Junjian et al., 2002), and the tims age of zircon in the gold bearing quartz vein of Ergou gold deposit is 2475 ± 19 MA (Shen Baofeng et al., 1998b). This type of gold deposit belongs to the primary gold deposit in the late syntectonic stage of greenstone belt (Shen Baofeng et al., 1997) P>
(2) Paleoproterozoic
Paleoproterozoic (2500 ~ 1800Ma) is a very important metallogenic epoch of large-scale mineralization in the Precambrian Chinese mainland. It is widely distributed not only in the North China block, but also in the Yangtze block. In addition to iron and gold, graphite, magnesite, talc, copper, lead-zinc and so on formed large-scale mineralization ring this period. Iron ore is still an important ore type for large-scale mineralization in this period, but its scale and distribution range are inferior to those of Neoarchean iron ore. There are two main types of ore deposits. Yuanjiacun superlarge iron deposit in Lanxian County, Shanxi Province, North China landmass (894.5 million tons of iron ore reserves) and Dahongshan superlarge iron copper deposit in Xinping County, Yunnan Province, Yangtze Landmass (458 million tons of iron ore and 1.35 million tons of copper reserves). The ore bearing rock series of Yuanjiacun superlarge iron deposit is Yuanjiacun formation of Paleoproterozoic Luliang group. Yuanjiacun formation can be subdivided into three sections, corresponding to three ore belts. The bottom of each ore belt starts from metamorphic quartz sandstone, passes through sericite quartz schist, sericite phyllite, chlorite schist and iron siliceous rock to chlorite schist, and sericite phyllite, that is to say, protolith is from clastic rock to chemical sedimentary rock and then to clay rock. The iron minerals of banded iron formation are dominated by hematite (or Specularite) and magnetite with oxide phase, and a small amount of siderite, black hard chlorite and mafic amphibole. The iron deposit is formed in a shallow marine Bay lagoon environment and belongs to the lake type of superior (Shen Baofeng et al., 1982). In the Paleoproterozoic Dahongshan group and Hekou group of the southwestern margin of the Yangtze Landmass, a very large Dahongshan Iron Copper Deposit and a large lalachang copper deposit occur. Dahongshan group is a set of marine volcanic eruption sedimentary rock series with shallow to medium metamorphism, which is divided into five groups. The iron ore body mainly occurs in the "subvolcanic facies" meta sodic lava (albite granulite) in the middle of Hongshan formation of the third group, while the main copper ore body occurs in the transition part of hornblende schist and marble in Manganghe formation of the second group. The ore bodies are distributed regularly along the volcanic institutions controlled by faults, and different types of ore bodies are formed in the periods of marine alkaline intermediate basic volcanic eruption, overflow and intermission. The Paleoproterozoic large-scale gold mineralization is mainly distributed in the North China block, and the deposit types are more diverse than the Neoarchean single greenstone belt syntectonic primary vein type gold deposits, including greenstone belt vein type gold deposits (such as Wenyu large-scale gold deposit in Xiaoqinling), There are also primary veinlet disseminated gold deposits (such as Paishanlou large gold deposit in western Liaoning) and light metamorphic clastic rock gold deposits (such as Maoling large gold deposit in Liaoning) in the late syntectonic greenstone belt. Paleoproterozoic is the earliest time for the formation of large-scale copper mineralization in China. Not only Dahongshan, Yunnan Province, but also the Paleoproterozoic Zhongtiao rift in the southern margin of North China block formed the super large Tongkuangyu Copper Deposit and a number of small and medium-sized copper deposits, such as Hujiayu and Bizigou, which constituted the concentrated area of copper deposits. The superlarge Tongkuangyu Copper Deposit (2.672 million tons of copper reserves) is hosted in the metamorphic volcanic subvolcanic rock series of Luotuofeng formation in Tongkuangyu subgroup of the Paleoproterozoic Jiangxian group. The host rocks of the ore body are mainly meta quartz crystal tuff and meta quartz porphyry, followed by meta quartz monzonite porphyry. The orebody is a flat lens. The mineralization type is mainly veinlet disseminated in the early stage and veinlet disseminated in the late stage. The main metal minerals are chalrite, pyrite, molybdenite, etc. Sun Dazhong et al. (1993) obtained 2166 ± The Re Os isochron age of molybdenite is 2108 ± The ages of diagenesis and mineralization are very close, ranging from 2166 to 2108 ma. The genetic type of the deposit is related to rifting extension and belongs to metamorphic marine volcanic porphyry copper deposit. The Paleoproterozoic is also the earliest large-scale mineralization period of Pb, Zn, B, magnesite and talc, and it is mainly distributed in the Liaoji rift in the eastern part of the northern margin of the North China block and caijiayingzi in the middle part of the northern Hebei block. Liaoji Paleoproterozoic rift is composed of Paleoproterozoic Liaohe Group and magmatic rocks in different stages of continental dynamic evolution. Horizontally, the rift is divided into northern slope area, central depression area and southern shallow platform area (Chen Rong)
Table 3-5 and table 3-6 show the temporal distribution and temporal evolution of copper deposits of more than 50000 tons in China
It can be seen from table 3-5 that the mineralization of Mesozoic copper deposits reached a climax, accounting for 44.38%, accounting for almost half of the country
Table 3-5 time distribution of copper deposits of more than 50000 tons in China. During this period, extensive intermediate acid magmatic intrusion and continental volcanic activities occurred in the middle and lower reaches of the Yangtze River, Northeast Jiangxi and the whole East of China, resulting in a number of world-famous ore belts such as the middle and lower reaches of the Yangtze River copper belt and Northeast Jiangxi copper belt
The late Paleozoic Copper Deposit is another metallogenic climax in China, with 17.49% copper reserves. Among them, 8.87% are related to intermediate acid intrusive magmatism, 6.00% to marine volcanism, 1.27% to basic ultrabasic magmatism, and 1.35% to marine basin sedimentation The Cenozoic copper deposits account for 13.07% of the total copper deposits in China, mainly contributed by Yulong porphyry copper belt, followed by continental basin sedimentation and karst valley sedimentation The fourth is the Mesoproterozoic copper deposits, accounting for 8.57%, mainly contributed by marine basin sedimentation, accounting for 8.06%; Marine volcanism contributed 0.51% The Paleoproterozoic copper deposits account for 7.60%, of which the intermediate acid intrusive magmatism accounts for 3.94% (Tongkuangyu) and the marine volcanism accounts for 3.59% The time evolution of copper deposits in China is shown in table 3-6. Table 3-6 shows that the time evolution of various mineralization is different. The most important mineralization is copper ore related to intermediate acid intrusive magmatism. This kind of deposit reached the climax in Mesozoic, and there was strong mineralization in Cenozoic and late Paleozoic. Further to the old age, the mineralization was very weak. The copper deposits related to marine volcanism are most intense in Late Paleozoic, Paleoproterozoic and early Paleozoic, and weak in other ages. The most important copper deposits related to marine basin sedimentation are Mesoproterozoic, followed by Neoproterozoic. The copper deposits related to basic ultrabasic magmatism are most important in the early Paleozoic, because the Jinchuan copper nickel deposit belongs to this age, followed by the late Paleozoic. Related to continental volcanism, only the Mesozoic copper deposits formed a climate in the east of China. Although there are many late Paleozoic continental volcanic activities in the northwest of China, none of them formed a very climatic copper deposit. Copper deposits related to the sedimentation of continental basins are concentrated in the Mesozoic and Cenozoic in southern China
