西昆仑库斯拉甫一带侏罗纪断陷盆地演化及成煤环境分析
Evolution and Coal-forming Environment Analysis of Jurassic Rift Basin in Kusilafu Area,Western Kunlun
摘要
Abstract
Rift basin is expanded with nearly N S trending in Kusilafu area of Western Kunlun, which is controlled by regional Kusilafu Fault in the west.The coal of this rift basin is mainly produced in Yangye Formation and Shalitashi Formation of Jurassic Yeerqiang Group,showing the characteristics of multiple layers,thin layer and unstable elongation.Freshwater shelly beach and petrified wood stacked layers are also appeared in multiple layers,which show accumulation characteristics of coal plant’s different burial places.Coal-forming environment belongs to the-continental sedimentary environment of lacustrine and fluvial swamp.The stretching tectonic ac-tivity in Late Indo-China orogeny may be offer the impetus for the forming of coal-bearing rift ba-sin nearby Kusilafu area.关键词
