赣中安源煤系发育特征及构造条件分析

DEVELOPMENT AND TECTONIC SETTING OF THE ANYUAN COAL MEASURES IN CENTRAL JIANGXI

摘要: 本文通过赣中地区上三叠统安源煤系沉积特征研究以及安源煤系发育过程中所产生的一系列构造特征与区域断裂构造之间的关系分析,初步认为安源煤系的形成受区域构造运动的挤压影响,并沿两组斜交断裂带侧边产生的剪切拉张作用的结果。

Abstract: On the basis of the sedimentary features of the Upper Triassic Anyuan coal measures in combination with the relationship between syndepositional structures associated with the development of the Anyuan coal measures and regional faults,the authors suggest that the Anyuan coal measures were formed in the conditions of shear extension along two groups of diagonal faults influenced by the compression of regional tectonic movements.
