    Lithostratigraphic framework on the southern margin of the Su-Lu orogen

      摘要
    • 摘要: 系统总结了苏鲁造山带南缘区域地质调查工作所取得的进展,将东海杂岩分解为新太古代至古元古代东海岩群和变质侵入岩。东海岩群由毛北岩组、演马场岩组、武强山岩组、虎山岩组和摩天岭岩组构成;变质花岗质侵入岩分为早期面状侵入体和晚期点状侵入体,超基性岩包体分为北西许沟岩带和南东蒋庄-岗尚岩带,变质杂岩呈一系列北东向和近东西向构造岩块分布,超高压变质岩块划分为4个岩片,密集发育晋宁期韧性推覆剪切带,后期普遍为印支期滑脱韧性剪切带叠加,形成复杂的韧性剪切系统。

       

      Abstract: The authors systematically summarizes the recent progress in the regional survey on the southern margin of the Su-Lu orogen.The Donghai complex may be divided into the Neo-archean to Paleopro-terozoic Donghai Group-complex and metamorphosed intrusive rocks.The Donghai Group-complex con-sists of the Maobei,Yanmachang,Wuqiangshan,Hushan and Motianling Formation-complexes.The meta-granitic rocks may fall into early-stage areal intrusions and late-stage isolated intrusions.Ultrabasic inclusions in meta granitic rocks fall into the NW-trending Xugou rock belt and SE-trending Jiangzhang-Gangshang rock belt.The metamorphic complex occurs as a number of NE-and E-W-trending blocks.The ultra-high-pressure(UHP )metamorphic blocks may be divided into four rock slices.The dense ductile shear zones occurred in three stages and the late stage witnessed overlapping of Indosinian detachment ductile shear zones of formation of complex ductile shear systems.
