| 摘 要： | 前人将唐巴勒-卡拉麦里缝合线置于伊吾县以南哈尔里克山塔水河一线。1993年巴瑞士等在伊吾西北大黑山发现超镁铁岩-镁铁岩洋壳残片,认为卡拉麦里蛇绿岩从伊吾西北大黑山一带向东延伸。2009年笔者参与伊吾县阿尔通盖一带1∶5万区域地质矿产调查工作,于伊吾县以北阿勒吞昆多一带发现阿勒吞昆多蛇绿混杂岩,该蛇绿岩中斜长花岗岩形成于早石炭世((351±6)Ma),大地构造为哈萨克斯坦-准噶尔板块及准噶尔微板块、唐巴勒-卡拉麦里古生代沟弧体系。在研究前人资料基础上,提出阿勒吞昆多蛇绿混杂岩为卡拉麦里蛇绿岩(属唐巴勒-卡拉麦里缝合线)向东延伸部分,唐巴勒-卡拉麦里缝合线(沟弧体系)西起唐巴勒,向东经达拉布特-卡拉麦里-塔克扎勒-大黑山至伊吾县阿勒吞昆多一带,可能延伸至蒙古境内。

| Abstract: | Predecessors took Tangbale-Kalamaili sutures in Tashui river,Haerlike mountain1],1993,Ba Ruishi was a professor from Nanjing University,when he worked in Yiwu,he found Montenegro ultramafic rocks-mafic rock fragments of oceanic crust in daheishan,southwest Yiwu,it is believed that kalamaili ophiolite should be extanded eastward from daheishan.2009,I had participated in 1∶50000 regional geological minerals survey,and found Aletunkunduo ophiolite mélange,plagiogranite in ophiolite melange was formed in the Early Carboniferous(351±6 Ma),in Kazakhstan-Zhungeer plate and Zhungeer micro-plates,Tangbale-Kalamaili.Based on lots of analysis and research,we proposed that the Aletunkunduo ophiolite melange is the eastward extension of Kalamaili ophiolite,Tangbale-Kalamaili suture line,through the Dalabute-Kalamaili-Takezhale-daheishan to Aletunkunduo,may be extended to Mongolia. |
