青藏高原东缘梯度带可溶岩地层特征

CHARACTERISTICS OF THE KARST STRATA IN THE GRADIENT ZONE OF THE EASTERN MARGIN OF THE QINGHAI-TIBET PLATEAU

青藏高原东缘梯度带地形复杂,以往岩溶研究程度低,发育特征与规律认识不足。本文通过收集地层、构造等区域地质资料,从研究区基本地质背景出发,论述了研究区从志留系到侏罗系出露的主要可溶性地层的分布、岩石成分和结构特征,为岩溶研究提供基础资料。

The terrain of the gradient zone in the eastern margin of the Qinghai-Tibet Plateau is complex, while the previous research regarding to the understanding of the development characteristics and patterns are insufficient. In this paper, starting from the basic geological background of the study area, the distribution, rock composition and structural characteristics of the main soluble strata exposed from Silurian to Jurassic are discussed by collecting regional geological information such as stratigraphic and structural factors, aiming to provide fundamental data for karst research.
