Ⅱ 蒙古古生代一種新的構造格架

O.Tomurtogoo

(Institute of Geology,Mongolian Academy of Sciences)

摘要蒙古古生代的北方超(級)地塊由多種類型的增生地體組成,它是西伯利亞南部褶皺帶的一部分。南方超(級)地塊是古特提斯洋向北方(中朝古大陸邊緣)多次前進中形成的,它屬於中朝克拉通北緣褶皺帶的一部分。兩者之間的構造線應為勞亞與岡瓦納古大陸塊的基底縫合線的一部分。

關鍵詞構造格架北方超(級)地塊南方超(級)地塊蒙古

蒙古古生代構成了亞洲內部造山帶[1,17],即所謂的阿爾泰造山帶[25]內一個幾乎完整的剖面,位於西伯利亞和中朝克拉通之間。本文作者利用地體拼貼的觀點,分析了蒙古古生代總體構造分帶性,這一觀點主要是由美國和加拿大學者提出並發展起來的[3,6,10]

正如地體分析所表示的那樣,蒙古地區的褶皺基底可劃分成北方和南方超(級)地塊,其邊界沿著新近建立起來的蒙古中部構造線延伸。這些超(級)地塊可進一步劃分成若干年齡不同和類型不同的地體(圖1)。

蒙古古生代的北方超(級)地塊的特點是:明顯地拼貼格局,廣泛地推覆構造,和多種多樣地復合地體。一般而言,從北向南時代由老變新。

這些超(級)地塊中的重要部分是圖瓦-蒙古超(級)地體,它是一個典型的微大陸構造[4,5,12,14,24,26],其基底非常不均勻。最近,發現了4個里菲期地體,從西向東組成復合推覆褶皺構造,它們是:(1)Ulaantaigyn被動大陸邊緣地體,它由已知的Sangilen前寒武紀「中間地塊」的東翼所代表,該地塊被中—上里菲期碳酸鹽所覆蓋,並與其變質基底分離。(2)Shishged-Dariv洋殼地體,它形成了兩個由相同類型的變質雜岩組成的外來體構造。(3)Khugein-Gol增生楔地體,包括廣泛分布的具藍片岩透鏡體的輝綠岩-綠片岩雜岩[15]。(4)巨大的Darkhad-Zavkhan-Orkhon安第斯型活動大陸邊緣地體,包括「早前寒武紀的變質核部」和「灰色」英雲閃長片麻岩、不同類型的上殼岩層雜岩(長石片麻岩-角閃岩-石英大理岩等)年齡分別為(2645±45)Ma、2370~1830Ma,約1700Ma的斜長岩侵入體[4,9,31]、以及外部巨型褶皺帶廣泛分布的中—晚里菲期變火山岩-變沉積雜岩和放射性年齡為1300~752Ma的眾多不同類型的花崗岩類侵入體[5,14,18]。合並後雜岩將上面提到的4個地體連接成一個超(級)地體,這些合並後的雜岩是由震旦紀到早寒武世(包括阿姆加階)海進系列含磷的淺海陸源碳酸鹽沉積物組成,其底部含有哈薩克型的類冰磧物[1,5,14]

湖區、Uvs Nuur和Eg-Uuri島弧地體從西側和東北側逆沖到圖瓦-蒙古超(級)地體之上。三個島弧地體形成所謂的湖區-Dda組合地體,該組合地體有獨特的推覆構造和時代為(695±25)Ma(Sm-Nd法)的特羅多斯型蛇綠岩,但是,更重要的是其成分上含有玻安岩熔岩、高鈦亞鹼性和鈣鹼性系列的熔岩、砂屑石灰岩、凝灰質濁積岩和放射性年齡為480Ma的I型花崗岩類[7,8,12,14,16,17,26,27,30]。蛇綠岩的性質和湖區-Dda組合地體的島弧雜岩清楚地指明這是一條超級俯沖帶。

北方超(級)地塊:1—超(級)地體;2—變質地體;3—島弧地體;4—洋殼地體;5~7—濁積岩地體南方超(級)地塊:8—增生柱地體;9—大陸邊緣地體;10—洋殼地體;11—硅鋁質島弧地體;12—硅鎂質島弧地體

主要的構造線:Ⅰ—Khangay剪切帶;Ⅱ—蒙古中部構造線

超(級)地體:1,2—圖瓦-蒙古大陸邊緣地體(1—北方部分;2—南方部分),包括Ulaantaigyn(1.1)和Darkhad-Zavkhan-Orkhon(1.3+2.2)大陸邊緣地體,Shishged-Dariv洋殼地體(1.2+2.1)和Khugein-Gol增生楔地體(1.3)

組合地體:4~6—湖區-Dda組合地體(包括4—Uvs Nuur地體;5—Eg-Uuri地體;6湖區地體),8,9—Khovd-Kharaa組合地體(包括8—Khord地體;9—Zag-Kharaa地體)

簡單地體:3—東Ehubsugul地體;7—巴彥洪古爾地體;10—蒙古阿爾泰地體;11—Khangay-Khentey地體;12—Duch-Gol地體;13—南阿爾泰-Ereehdava地體(斷線是Ikhbogd-Kerulen縫合線);14—外阿爾泰地體;15—Ajbogd地體;16—戈壁地體;17—戈壁-天山-Nuketdavaa地體;18—Zamin Und地體;19—Toto山地體;20—Solonkher地體

對湖區-Dda組合地體的北部,侵位到東Khnbsugul變質地體中,區域構造上位於西伯利亞克拉通南部褶皺邊緣內的Khamardaban克拉通地體的西南端。該地體是由具寬廣的花崗岩穹窿構造和早前寒武紀—志留紀帶狀變質雜岩組成[27]

在圖瓦-蒙古超地體的東緣有一個狹長的、外來的巴彥洪古爾洋殼地體,該地體由巨厚的單質蛇紋混雜岩帶組成,呈巨大的塊狀,為蛇綠岩剖面出露的部分[7,14]。蛇綠岩是由年齡在569Ma(Sm-Nd法)的輝長岩、席狀岩牆雜岩和含有海相地層的E型和T型洋中脊玄武岩枕狀熔岩組成。海相地層中含有早寒武世化石[7,18]

南方超(級)地體的南部,是由一系列下、中古生代濁積岩地體組成的[1,11,12,16,17.29]。特別是Khovd-Kharaa組合地體出現的露頭主要是由寒武紀-奧陶紀單成分火山質濁積岩和下伏具破碎的蛇綠岩的俯沖混雜岩組成,這清楚地表明它們是增生楔的一部分。那時,相同時代的具有混雜蛇綠岩和厚層亞長石砂岩質復理石的蒙古阿爾泰濁積岩地體可能是一個被埋藏的洋中脊。在濁積岩地體的南部體系中有一個獨立的構造,即Khangay-Khentey地體,其特點是由巨厚的志留紀—泥盆紀和早、中石炭世外來濁積岩組成。最近發現,該地體是一小洋盆的碎片,因為它在晚志留世—泥盆紀沉積的Adaatsag-Onon濁積扇整合地蓋於具有席狀岩牆系列和N型洋中脊玄武岩的枕狀熔岩之上[14]

上面介紹的北方超(級)地塊中,所有的地體都被不同類型的疊覆雜岩所覆蓋。主要的成分是古生代中期火山成因的陸源沉積(不包括Khangay-Khentey地體)和含不同類型磨拉石的晚古生代陸源火山岩[2,11,12,16,17,26,29]

蒙古古生代的南方超(級)地塊與北方超(級)地塊相比有完全不同的構造。前者表現出線性構造對稱的特點以及由大陸邊緣加長的地體有規則地交替(在剖面上),並具有相似的或狹形的地體組成了古洋殼雜岩。

由南阿爾泰-Ereendavaa,戈壁-天山-Nu-Ketdavaa和Toto山大陸邊緣地體組成的這些一級構造都具有相當單一的早加里東的褶皺基底,這些基底中含有不同時代的雜岩。因此,可以認為這些地體通常是一個單獨褶皺區的組成部分。在這一褶皺基底之上,新元古代碳酸鹽-片岩雜岩佔主導地位,它位於下伏的前寒武紀早期多次變質的雜岩和「灰色」片麻岩之上[1,4,12]。前面提到的雜岩在許多性質與在中期克拉通北緣充填在「古地塹」中的渣爾泰群和白雲鄂博群的變質雜岩相同[19,20]。這些地體的基底之上的剖面是震旦紀—早寒武世陸棚碳酸鹽沉積,其上部含有古杯海綿化石。只有在南阿爾泰-Ereendavaa地體基底上的Ikhbogd-Kerulen縫合帶內,上部的陸棚碳酸鹽被相同年齡的蛇綠岩突然地置換,它類似於中朝克拉通北部的鄂爾多斯縫合帶中的蛇綠混雜岩[1,12,14,19,20]。以上描述的大陸邊緣地體中的早加里東基底被中寒武世的S型花崗岩類侵入體所穿切[1,12]

大陸邊緣地體覆蓋的沉積物包括中奧陶世到早石炭世的陸棚碳酸鹽-陸源岩,它們的下部層位的某些部分被單成分的濁積岩所替代,而剖面其它地段被志留系—泥盆系堤礁或泥盆系—早石炭世火山成因的磨拉石建造所取代[1,12,17,23,26,27,29]。偶爾,晚寒武世—早奧陶世裂谷成因的火山-復理石雜岩出現在沉積蓋層中,這些雜岩含有大陸拉斑玄武岩成分的變質基性岩。

此外,在大陸邊緣地體中還有晚古生代至早三疊世不同類型疊置的雜岩,它們主要是由陸源火山岩和大陸或海岸磨拉石組成[1,2,12]

南方超(級)地塊中,二級地體是以古海洋縫合線的形式存在的[13,14,23,27,29],它們的特點是推覆構造和多種類型的火山沉積雜岩發育,並伴隨有含薄層蛇紋大理岩-放射蟲岩層的利古里亞(Ligurian)型蛇綠岩,蛇紋大理岩-放射蟲岩層位於基性玄武熔岩的上部單元。這些雜岩的時代范圍是變化的,外阿爾泰洋殼地體,Ajbogd、戈壁和Dzamin Uud島弧地體時代為志留紀—早石炭世,最南部Solonkher島弧地體為中石炭世—晚二疊世。與後者年齡相似的還有Duch-Gol增生楔地體,它的位置正相反,位於超地塊的北緣。典型的泥盆紀—早三疊世俯沖混雜岩出現在這個地體中,該地體主要是由復理石與綠片岩變質岩和可能是泥盆紀的殘留蛇綠岩混雜而成[17]。更重要的是Solonker地體和Duch-Gol地體的晚古生代雜岩中伴隨有不同的動物群,前者通常是典型的特提斯動物群,而後者主要是北方動物群[1,17,23]

蒙古古生代地體拼貼的形式可用下面的地球動力學模式加以解釋(圖2)。

構造格架圖中的阿拉伯數字表明了洋盆、增生楔和縫合帶的形成位置:①,③,④古亞洲洋洋盆(①阿爾泰-Khentey洋盆;③Shishged洋盆;④Dda洋盆);②古太平洋的Khangay-Khentey洋盆;⑤,⑥—具大洋型地殼的消減槽(⑤Ikh Boyd-Kherlen消減槽;⑥戈壁-阿爾泰消減槽)和古特提斯洋的洋盆(⑦外阿爾泰洋盆;⑧南蒙古洋盆;⑨內蒙古洋盆)

在古元古代,整個蒙古地區古生代地質體是瑞典-芬蘭型活動帶的一部分。開始,這條帶極有可能具有西太平洋型的現代大地動力學系統,但是後來,由於格林維爾構造作用而固結(concolidated),最終變成了超級泛大陸的一部分。

在里菲期—早奧陶世,發現蒙古古生代超(級)地塊以圖瓦-蒙古微大陸形式存在於古亞洲洋內,它的周圍是洋盆。然而,古生代南方超(級)地塊成為中朝大陸的戈壁邊緣的一部分。由於古特提斯洋向華夏古陸不斷前進,北方超(級)地塊受到破壞作用的影響。在這些事件中,古亞洲洋中的古蒙古部分可看作是大陸增生系統中的一個差異侵蝕盆地。它們中的大多數在早奧陶世終結並焊接在西伯利亞克拉通上,最後轉變成廣闊的亞洲北部加里東大陸。

在中奧陶世和三疊紀侵入作用開始的時間內,北亞大陸在其南部被古亞洲洋的蒙古-鄂霍次克(Khangay-Khentey)小洋盆所包圍。中朝大陸的戈壁邊緣逐漸向西伯利亞運動,並在古特提斯的前進作用中遭受破壞,由於「威爾遜旋迴」而再次「焊接」。

到中三疊世,北亞板塊與中朝板塊斜向碰撞,導致了蒙古-鄂霍次克洋盆Khangay-Khtutey部分的完全消失,最終導致了蒙古古生代聯合大陸殼的形成。

對蒙古古生代地體構造的分析可得出如下結論:

(1)蒙古古生代的北方超(級)地塊是一個古生代的推覆-褶皺區。它是由形成於加里東古亞洲洋(加里東地體系統)和古太平洋的華力西蒙古-鄂霍次克洋盆(Khangay-Khentey地體)中多種類型的增生地體所組成。在亞洲內部造山帶的區域構造中,蒙古古生代的北方超(級)地塊是包圍西伯利亞克拉通的南部褶皺帶的中亞古生代褶皺帶的一部分[17]

(2)蒙古古生代的南方超(級)地體是一個碰撞型的華力西褶皺帶,它是在古特提斯洋向北方(現代方向)中朝古大陸邊緣多次前進中形成的。該事件隨著早、中、晚古生代「威爾遜旋迴」的產生。在亞洲內部造山帶的區域構造上,蒙古古生代的南方超(級)地塊屬於中朝克拉通北緣褶皺帶的額爾齊斯-興安褶皺帶[28]

(3)蒙古的線性邊界可劃分成上面提到的亞洲內部造山帶的增生和碰撞褶皺帶,稱之為蒙古中部構造線。該構造線是一條向西延續的已知的蒙古-鄂霍次克構造線[17],並一直進入中亞的內部地區,它代表了亞洲北部古大陸與中朝古大陸斜向碰撞的痕跡。因而,蒙古中部構造線是勞亞與岡瓦納古大陸塊的基底縫合線的一部分。
