煤系划分和时代归属,地质构造运动是一个重要因素,同时也应兼顾其它方面因素。对粤东地区东吴运动表现的认识,以及以此为主导而引起沉积、地球化学、古生物组合诸特征的差异和沉积环境上的变化,可将粤东二叠纪煤系分为兴梅组和龙潭组,并分别归属早、晚二叠世。整个二叠系沉积特征反映了一个构造运动所导致的完整的沉积旋回,反映了当时总的海水进退规程及构造运动对成煤作用的影响。了解这些,对今后结合古构造制约下的古地理、古气候条件来研究煤系及聚煤带的生成、迁移和分布规律,进而探讨煤系的沉积模式将是有益的。
Coal classification and the era belongs to the geological tectonic movement is an important factor, but also should take into account other factors. Based on the understanding of the performance of Soochow movement in eastern Guangdong and the changes of sedimentary, geochemical and paleontological features and the changes in sedimentary environment led by it, the Permian coal measures in eastern Guangdong Province can be divided into Xingmei Formation And Longtan Formation, and belong to early and late Permian. The sedimentary characteristics of the whole Permian reflect the complete sedimentary cycles caused by a tectonic movement, reflecting the then seawater rules and the effect of tectonic movement on coal formation. With these understandings, it is beneficial to study the formation, migration and distribution of coal measures and coal measures in the future with the paleogeography and palaeoclimatic conditions under ancient constraints.
