藏南卓木日–俗坡下带地质构造特征浅析

Analysis on the Geological Structure Characteristics of the Lower Zone of Zangnan Zhuo Wood Day

摘要: 本文主要研究西藏隆子县的卓木日–俗坡下一带，该带出露地层主要为上三叠统涅如组。构造样式主要表现为一系列复式倒转褶皱配套大量逆冲断层组成。断层由北向南逐渐增多，尤其在古堆–穷科当–隆子一带，雄曲两侧构造变形较为强烈，发育大量逆冲断层，断层多具分枝复合形象，构成一个断裂带，断裂带将地层分割成构造岩片。局部泥质含量高的软弱岩层发育强片理化带。该带内地层中的次级、小型褶皱变形极为普遍，变形程度总体由北向南逐渐增强；北部主要表现为斜歪褶皱，南部则出现大了尖棱、平卧褶皱等。

Abstract: This paper mainly studies the common slope area of Zhuo Wood Day-Vulgar Slope in Tibetan Longzi, the exposed stratum of which is mainly Upper Triassic Nirvana. The tectonic pattern of this area is mainly composed of a series of complex inverted folds supporting a large number of thrust faults. These faults gradually increase from north to south, especially in the ancient heap-poor subjects - Longzi area; the tectonic deformation on both sides of the male is stronger with the development of a large number of thrust faults. Faults have many branches and compound images, and then it constitutes a fault zone. This fault zone divides the formation into tectonic rocks . The local high mud content of soft rock is developed into competent schistositilization. The secondary and small folds in the strata are extremely common, The overall degree of deformation gradually increased from north to south; the northern part of the main performance for the oblique crooked fold, while the south is the sharp edges, recumbent fold and so on.
