WUDALIANCHI VOLCANIC ROCK DEPOSIT

1. Wudalianchi can buy local specialties as follows:
Wudalianchi mineral water (one of the world's three major cold spring mineral water, with unique health care function), xinlongquan Laojiao liquor, jiefubao volcano tonic stone (Magic foot rubbing stone), "volcanic red" trace quality egg (improving immunity), pure natural wild vegetables, China's only "mineral milk", and "natural milk" Xianchi brand volcanic mineral mud series skin care procts, Wang donkey dried tofu, etc. Wudalianchi specialty is composed of special mineral characteristics, with a strong role in health care.

2. Around Wudalianchi, there are 14 volcanic bodies and a series of volcanic mineral springs, which constitute a unique and typical volcanic landscape, so it is called "volcano museum". It is a famous volcano resort in China. Because of the river channel blocked by volcanic lava, five connected volcanic barrier lakes have been formed, so it is called "Wudalianchi"
volcanic stone (commonly known as pumice or porous basalt) is a kind of functional environmental protection material, which is a very precious porous stone formed by volcanic glass, minerals and bubbles after volcanic eruption. Volcanic stone contains dozens of minerals and trace elements such as sodium, magnesium, aluminum, silicon, calcium, titanium, manganese, iron, nickel, cobalt and molybdenum, which has far-infrared magnetic wave without radiation, After the relentless eruption of the volcano, after tens of thousands of years, human beings have found its value more and more.

3. There are professional sculptors who can carve blocks of volcanic rocks into flowerpots and rockery bonsai, and carve them into flowing water. It has a very good shape
volcanic stone is now in the foot massage shop in Shanghai and Guangzhou. It is used for health massage, that is, rubbing feet. It costs more than 20 yuan, but the cost is very low

4. My family is Wudalianchi. I don't think there is any radiation. Otherwise, we common people will get a lot of money if we live around here all day?? You mean stones with honeycomb holes? There's no radiation. Someone picked it up. And we have a scenic spot there is called the stone sea, a piece of volcanic rock, is left after the eruption

6. Wudalianchi Volcano Group in Heilongjiang Province is generally considered to be composed of 14 volcanoes. If Lianhua Mountain in the western part of the volcanic area is included, Wudalianchi volcano group should be composed of 15 volcanoes with a volcanic rock distribution area of more than 800 km2. Laoheishan and Huoshaoshan erupted less than 300 years ago from 1719 to 1721. They are the most exact active volcanoes with historical records, eruption time and location in China< There are 13 craters in the Holocene of Jingbohu volcano in Heilongjiang Province, all of which are compound volcanoes. It is speculated that the latest Holocene Volcanic Activity in Jingpohu may be around 1000 years. From the existing volcanic geological and chronological evidence, there is no objection to the Holocene Volcanic eruption in Jingpo Lake< The Tianchi volcano in Chang Mountain, Jilin Province, is the most complete Cenozoic composite volcano with multiple origins preserved in China, and its main peak, jiangjunfeng, is located in North Korea, with an altitude of 2749 M. The volcanic activity of Tianchi volcano has experienced three stages: shield formation (2.77-1.203 Ma, early Pleistocene), coning formation (1.12-0.04 Ma, middle late Pleistocene) and Holocene eruption. The magma composition of the three stages represents the evolution process from basaltic to trachyte to alkali fluid (Liu Ruoxin et al., 1998; Liu Ruoxin et al; Fan Qicheng et al., 1999). There are many eruptions in Chang Mountain Area in history;, The two eruptions of Tianchi volcano in 1668 and 1702 are credible (Cui Zhongxie et al., 1995). Based on volcanic geology and detailed 14C chronology, there have been at least two large-scale eruptions (1199 and about 5000 years ago) since Holocene. The eruption of Tianchi volcano in 1199-1201 is the largest eruption event in the world in 2000 years. At that time, the ejected ash fell as far as the sea of Japan and northern Japan< The Longgang Volcano Group in Jilin Province has more than 160 low volcanic cones, showing the characteristics of high-density and multi center explosive eruption. From the west of Jingyu County to the junction of Jingyu and Huinan, the low level crater (Maar), represented by Longwan, has become a major landscape of Longgang volcano group. Among them, Dalongwan and sanjiaolongwan have been developed into the only low level crater scenic spots with beautiful scenery in China. In the area surrounded by Longwan, a towering volcanic cone, Jinlongdingzi volcano, has sprung up. Longgang volcano is one of the few quaternary volcanoes with eruptive activity in modern China< The eruption of dayingshan volcano in 1609 was recorded by Xu Xiake. According to the characteristics of volcanic geology, geomorphology, magmatic evolution and hydrothermal activity, heikongshan, dayingshan and Maanshan are generally regarded as Holocene volcanoes. So far, there is no chronological evidence that the "mountain fire" of dayingshan volcano in 1609 recorded in Xu Xiake's travels was the cause of the eruption. According to Li Gengen's "records of lieyishan", there are many volcanoes in Tengchong. According to the records, there were many eruptions in Chenghua, Zhengde, Jiajing and Wanli years of Ming Dynasty (1465-1620 A.D.), which indicates that there were eruptions in Tengchong volcano area hundreds of years ago. Tengchong Volcanic Area is the most significant area of geothermal display in active volcanic area in China. For example, the water temperature in Rehai area is about 100 ℃. In recent years, the hydrothermal activity seems to be increasing, and there are many hydrothermal explosions. The existence of magmatic shock type earthquake in microseismic observation (Han Xinmin et al., 1996), seismic sounding profile and magnetotelluric sounding results all indicate the possible existence of magmatic chamber in crust (Liu Baocheng et al., 1986; Sun Jie et al., 1989; Bai Denghai et al., 1994; Whether all of these are brewing new eruption danger, we should pay special attention to the future activities of Tengchong volcano< The ashkule volcano group is located in the West Kunlun Mountain, about 120km south of Yutian County, Xinjiang, on the northwest margin of the Qinghai Tibet Plateau. It is composed of more than 10 main volcanoes and dozens of sub volcanoes, including Xishan, ashshan, Daheishan, wuluk, labyrinth, Yueya, yak, Heilong, MATI, Dongshan and shiaoshan. Most of these volcanoes were formed in Quaternary. The latest eruption was Ashe volcano on May 27, 1951 (Liu Jiaqi and Maimaiti Yiming, 1990). According to Xinjiang Daily on July 5, 1951, "a volcanic eruption occurred at 9:50 a.m. on May 27 in the area of dabanxigou, Kunlun, south of SUBASHI, Yutian County. The first explosion saw a loud bang on the top of a mountain, and then soot came out from the top of the mountain like a big column. Then it broke out three times in a row, only a few minutes apart each time. There was no loud noise, only smoke on the ash. In the next few days, I saw the volcano smoking again. This is also the first report on volcanic eruption since the founding of new China. According to the report and relevant investigation opinions, the volcanic eruption is explosive eruption, and there is no lava overflow. Since dozens of volcanoes here are well preserved, it has been 50 years since the eruption in 1951. In particular, there is no overflow of lava flow and there is no obvious geomorphological sign. Therefore, Deng Wanming (1989) questioned whether Ashan volcano (or No.1 volcano) was the volcano erupted on May 27, 1951. This has raised a big question mark for the latest active volcanoes in China, and it can be seen that it is not easy to determine the time and location of volcanic eruption recorded in history.
