本文对近年来一些书刊所提出的“海相成煤”观点发表了不同的意见。所谓海相应该理解为正常海或开放海也即浅海。但一些作者提出我国一些所谓属海相成煤的实例从他们分析的古地理环境看来并不是正常海而还是滨海环境,再对我国一些含石灰岩高的煤系进行沉积环境分析,发现它们主要的沉积环境也是滨海环境。浅海能否形成腐植煤是一个值得深入研究的问题,但从现在资料看,早古生代石煤可能是正常海形成的。
In this paper, we put forward different opinions on the viewpoint of “marine coal preparation” proposed by some books and periodicals in recent years. The so-called sea should be understood as a normal sea or open sea that is shallow sea. However, some authors propose that some so-called marine coal-forming examples in our country do not appear to be normal sea or coastal environment from the palaeogeographic environment they analyzed. Then we analyze the sedimentary environment of some coal-bearing limestone-rich coalfields in our country and find that they are mainly The sedimentary environment is also a coastal environment. Shallow sea can form humus is a problem worthy of further study, but from the current data, the Early Paleozoic coal may be normal sea formed.
