塔里木板块主要构造期周缘边界性质分析

Analysis of the Boundary Properties of the Tarim Block during the Main Tectonic Period

塔里木板块经历了复杂的构造-沉积演化过程,周缘地质条件复杂。通过对塔里木板块周缘盆-山块体边界、大断裂及构造事件等调研,结合前人对区域构造演化研究的认识,进一步明确了塔里木板块主要构造期周缘边界类型、性质及区域应力场等地质特征。

The Tarim block has experienced a complex tectonic-sedimentary evolution process,and its periphery geological conditions are complex.Based on the investigation of basin-mountain block boundary,major faults and tectonic events in the periphery of the Tarim block,combined with the previous understanding of regional tectonic evolution,the geological characteristics such as the types,properties and regional stress field of the periphery of the Tarim block during the main tectonic period are further defined.
