峡江地区推、滑覆构造特征及成因机制探讨

摘要

This paper comprehesirely studys reqional investigation material of Xingan sheme group (1:50 000)inGanzhong Xiajiang area, puts forward the opinion that the stratun of the devonian peviod is external nappeand slidestructure in the area for the firnt time, considers that Indosinian the devonian system nappeanded from sw to NE,then ex-tended and slided to SE in Yanshan Period. The paper presents dominately the character of nappeand slide structure,analizes initially mechanism of cause of formation, which all based on detailed outside firsthand material.%通过对赣中峡江地区1：5万新干图幅区调资料的综合研究，在该区首次提出了泥盆纪地层为外来推、滑覆体的观点，认为印支期泥盆系是由SW向NE推覆，燕山期再向sE伸展滑脱。以详实的野外第一性资料，着重阐述了推、滑覆构造特征，初步分析了其成因机制。
