小秦岭西段拆离－变质杂岩核构造

DETACHMENT-METAMORPHIC COMPLEX CORE STRUCTURE CONFIGURATION

Xiaoginling Mt is located at the south margin of the North China Palaeo-continent consisting of 2 sub-tectonec units, ie. ,Taihua Anteklise and Jinduitai Synklise. The Taihua Anteklise is the metamorphic complex-outcroped area (without coverrock)as thermal domed short axis anticlinorium neighbouring acient regional mylonite on the north and south and border weihe fault depression (with Cenozoic sedimends) in the north and Jinduitai synklise in the south by normal faults. The synklise is subdivided into 3 structural association belts chaiacterized by detatchment association areas with extension sliping overlap. The distribution shows a detatchmen-tmetamorphic complex core structural configuration. Study of the structural model and the dynamic background will shed a new light to the integral tectonic style of Xiaoqinling Mt regional geology as well as Au-metallogeny in the area.
