Geological characteristics and tectonic significance of ophiolite mélange in Ma'anshan area of the eastern Inner Mongolia

摘要:
二连浩特—贺根山蛇绿岩带是中亚造山带东部出露面积最大的晚古生代蛇绿岩带，曾被认为是华北板块和西伯利亚板块最后碰撞的缝合线位置，关于其构造属性仍存在争议。新识别出的内蒙古马鞍山地区蛇绿混杂岩位于兴蒙造山带东部，是二连浩特—贺根山蛇绿岩带的东延部分，这套蛇绿混杂岩的发现填补了二连浩特—贺根山—黑河缝合带中段的空白，为古亚洲洋构造域演化提供了新的证据。通过对马鞍山地区蛇绿混杂岩开展岩相学、地球化学、年代学研究，发现马鞍山地区蛇绿混杂岩由岩块和基质构成，其中岩块主要为蛇纹石化橄榄岩、橄榄岩、辉绿岩、玄武岩、高镁安山岩、安山岩、流纹岩，基质主要为浊积岩; 蛇纹石化橄榄岩具有俯冲带(supra-subduction zone，SSZ)型蛇绿岩特征，辉绿岩具有SSZ型构造背景成因特征，玄武岩具有富集型洋中脊玄武岩(enriched mid-ocean ridge basalt, E-MORB)和岛弧玄武岩特征, 指示其形成于弧后盆地环境。从马鞍山地区蛇绿混杂岩中获得的辉绿岩锆石U-Pb年龄为(344.4±1.4) Ma，与前人在贺根山地区蛇绿岩中获得的年龄相近，证实本区存在板块消减带(缝合带)，对厘定区域构造格架具有指导意义。
Abstract:Erlianhaote Hegenshan ophiolite belt is the largest exposed area of Late Paleozoic ophiolite in the eastern part of the Central Asian Orogenic Belt. It was once considered to be the suture zone of the last collision between the North China Craton and Siberian Plate, and there is still controversy in its tectonic attributes. The newly identified ophiolitic mélange in Ma'anshan area of Inner Mongolia is located in the eastern part of Xingmeng Orogenic Belt and is the eastern extension of the Erlianhaote-Hegenshan ophiolite belt. The discovery of the ophiolitic mélange fills the gap of the middle section of the Erlianhaote-Hegenshan-Heihe suture zone and provides new evidence for the evolution of Paleo-Asian Ocean tectonic domain. It was found that the mélange is composed of blocks and matrix through petrographic, geochemical and chronological studies of Ma'anshan ophiolitic mélange. The blocks are serpentinized peridotite, peridotite, diabase, basalt, high-magnesium andesite, andesite and rhyolite, and the matrix is mainly turbidite. The serpentinized peridotite has the characteristics of supra-subduction zone (SSZ) type ophiolite, and the diabase has the characteristics of SSZ tectonic background genesis. The basalt has the characteristics of (enriched mid-ocean ridge basult E-MORB) and island arc basalt, indicating that it was formed in a back-arc basin environment. The zircon U-Pb age (344.4±1.4) Ma of the diabase in Ma'anshan ophiolitic mélange is similar to the age obtained by previous researchers from Hegenshan ophiolite, confirming the existence of a subduction zone (suture zone) in this area, which is of great significance for the determination of the regional tectonic framework.
