Structural styles and their control effect on Jurassic coalfield in Xinjiang

Xinjiang region has abundant Jurassic coal resources,but its exploration and developing degree are much lower,so one systematic research on its coalfield structural distribution pattern and structural styles is necessary. Based on the tectonism dynamic characteristics of main coal basin,through the analysis and research on years of regional ge- ology and coalfield exploration data,this paper divided the coal-controlled tectonic in Xinjiang region into four struc- tural patterns:Compression,Extension,Torsion and Invertion. Based on this division,also according to the geometric and kinematic features of coal-controlled structural association,this paper divided the Xinjiang coal-controlled structure further into six subgroups and 18 patterns,in which,the Imbricated Thrust Structure,Nappe Detachment Structure, Fold Structure and Strike Slip Structure have main control actions on coal measures,seam preserving status and mining geological conditions.
