| 摘 要： | 双阳地区构造极为复杂，且有多期聚煤作用。上三叠统大酱缸组聚煤作用主要发生于古生界纬向断拗带之中，聚煤盆地类型以对冲断层谷式为主。下侏罗统太阳岭组聚煤作用是在纬向构造体系和新华夏构造体系的复合叠加环境下形成的，下白垩统的二道梁子组聚煤作用受控于双阳盆地轮廓的限制，两时期的聚煤盆地类型皆以开阔坳陷式为主。下白垩统的长岭组聚煤作用形成于金家屯组安山岩上的北东向断陷带之中，聚煤盆地类型以半地堑式为主。研究表明，双阳地区今后的找煤应突破双阳盆地周缘找煤的框架，物探、槽探相结合在南北向上寻找被第四系覆盖的大酱缸组煤系。

| Abstract: | The geological structure is very complicated and there is a multi-periodcoal-accumulating process in Shuangyang area. Coal-accumulating process of the upper Triassic Dajianggang Formation occurred mainly in the latitudinal fault-fold zonewbile the coal-accumulating process of the lower Jurassic Taiyangling Formation wastook place in a compound environment formed by the Latitudinal structural system andthe Neocathaysian structural system.The coal-accumulating process of the lowercretaceous Erdaoliangzi Formation was restricted within Shuangyang basin,in which thetwo period coal-accumulating process occurred in a basin belongs to a type of widedepression. The coal-accumulating process of the lower Cretaceous ChanglingFormation was formed in a half graben of the NE trending fault zone which posited on theJinJatun Formation andesite. The research results indicate that the future coalprospeeting should be around Dajianggang Formation in a region covered by Quatelnarysediments. |
