徐沛煤田控煤构造特征及成因分析
|
摘要
徐沛煤田石炭—二叠纪成煤以来,经过多期次构造运动,对煤系的赋存产生较大影响。利用徐沛地区近年来最新的地震、钻探等勘查成果,运用板块构造学和地质力学的观点,对区内控煤构造特征及其演化进行了探讨。分析认为,本区的控煤构造在空间上呈现出一定的规律性:丰沛区以伸展型和平移走滑型控煤构造样式为主,九里山区和贾汪区以压缩型控煤构造样式为主;近东西向掀斜断块的形成是印支期挤压运动和喜马拉雅期拉张运动的结果,走向近南北的右旋平移走滑断裂形成于新近纪以来右旋压剪性活动,构造面向NW倾的褶皱-逆断层构造型式形成于印支期NW-SE挤压力的作用,构造面向SE倾的褶皱-逆断层构造型式则形成于燕山期SE-NW挤压力的作用。
Since Permo-Carboniferous coal-forming in the Xuzhou-Peixian coalfield,the succeeding multiple phases of tectonic movements have been largely impacting the occurence of coal measures.Based on up to date seismic prospecting and drilling data in the area,using plate tectonics,geomechanics viewpoints,the coal-controlling structural features and their evolution have been discussed.The analysis suggests that the coal-controlling structures in the area present a certain extent of spatial regularity: in the Fengxian-Peixian area are mainly extensional and strike-slip structures,while in the Jiulishan and Jiawang areas mainly compressional structures.The formation of near EW tilted fault blocks were resulted by the Indosinian compressional movement and the Himalayan extensional movement;near NS right-lateral strike-slip faults were formed during right-lateral compresso-shearing movement since the Neogene;NW dipped fold-reversed fault structural type was formed during Indosinian NW-SE compressional movement and SE dipped fold-reverse fault structural type during the Yanshanian SE-NW compressional movement.
