新疆精河县中泥盆世汗吉尕组硅质岩成因及环境分析
Genesis and Environmental Analysis of Siliceous Rocks from Middle Devonian Hanjiga Group in Jinghe County, Xinjiang
摘要
Abstract
The siliceous rocks of Middle Devonian Hanjiga Group are well developed in Jinghe County,Xinjiang.The research about the genesis of these siliceous rocks has important significant to analyze the sedimentary environment,basin structure,regional geological structure and regional dynamics evolution.Through carrying out 1 ∶ 50000 geological mapping,profile measurement,petrological and geochemical analysis,the distribution,origin and formation environment of Hanjiga siliceous rocks have been studied.The results show that these siliceous rocks were formed in the bathyal depositional environment with relatively weak hydrodynamic conditions,belonging to the siliceous rocks of volcanic causes mixed with turbidite formation.关键词
