摘要
华北聚煤区南部以盖层构造差异和聚煤作用的'南型北相'性质而有别于华北主体。秦岭-大别山造山带和双沟推覆带-郯庐断裂带,是控制煤田构造格局形成和发展的两大区域构造系统。按板块构造观点,研究区的构造演化可划分为3个阶段:(1)古陆壳板块演化——聚煤坳陷形成阶段;(2)板内挤压变形——煤田构造主要形变期;(3)伸展裂陷阶段——决定煤系现今赋存状况。
The southern part of North China coal-accumulation (NCC) is different from the main part of NCC in its distinct cover structures and the so called 'southern type but northern facies' characteristics of coal-accumulating process.The two regional tectonic systems controlling the formation and development of the tectonic framework of coalfields are Qinling-Dabie orogenic belt, Shuanggou nappe zone and Tancheng-lujiang fault zone.The tectonic evolution of the studied zone is divided into three stages as viewed from the plate tectonics. ( 1 ) the stage of evolution of palae-continental plates—the formation of subsidence of coal-accumulation; ( 2 )the interplate compression—the major deformation period of coalfields; ( 3 ) the extensional stage—resulting in the distribution of coal measures of today.
