摘要
采用岩相旋回法、标志层法和煤岩层组合特征等多种方法,对红阳煤田的岩煤层进行综合对比,认为该煤系沉积稳定,标志层明显,易于辨认及对比,岩性、岩相变化有一定规律可循,具有比较明显的旋回结构,煤层层位在旋回上有一定的分布规律,为一套海陆交互相滨海平原型沉积。
Through multiple methods of lithofacies cycle, marker beds and coal-rock association carried out strata and coal seam comprehensive correlation in Hongyang coalfield. Considered that the coal measures have stable deposition, distinct marker beds, easy to identify and correlate, lithological and lithofacies varying have regular patterns. The coal measures have obvious cycling structure; coal seam horizon has certain distribution pattern cyclically, thus a set of marine, terrestrial alternative littoral plain deposit.
