赣中峡江地区推滑覆构造特征及成因机制

通过对赣中峡江地区1：5万新干图组区域地质调查资料的综合研究。作者首次在该区提出了泥盆纪地层为外来体的观点，认为是印支晚期-燕山早期泥盆系由NW向SE推覆，燕山晚期再向SE伸展滑脱。江西北部和南部均有EW，NNE推，滑覆构造存在的报道，资料较多，但对赣中很少见有报道，此次峡江地区推，滑覆构造的发现和确定。对认识赣南与赣北NNE向推，滑覆构造的联系乃至全区整体认识，在地质构造上有着重要的意义，本文以详实的野外第一性资料，着重阐述了其推，滑覆构造特征，并分析了成因机制。

Features and genetic mechanism of thrust nappe and sliding nappe structures in the Xiajiang area, central Jiangxi

Abstract: According to an integrated study of the data of regional survey of the 1:50000 Xingan Map Series in the Xiajiang area, central Jiangxi, the authors for the first time propose the view that the Devonian strata in the area are an allochthon and hold that the Devonian was thrust from NW to SE in the late Indosinian to early Yanshanian and then again underwent extension and detachment to the SE in the late Yanshanian stage. There are many reports about the existence of thrust nappe and sliding nappe structures in northern and southern Jiangxi but few reports have been read that they exist in central Jiangxi. The discovery and determination of thrust nappe and sliding nappe structures in the Xiajiang area this time have great tectonic significance for the understanding the relation of the NNE-trending thrust nappe and sliding nappe structures between southern and northern Jiangxi and even the understanding of the whole. This paper mainly deals with the characteristics of the thrust nappe and sliding nappe structures with detailed field first-hand data and preliminarily analyzes their genetic mechanism.
