Studies showed that there were two typical combinations of the facies in the filling sedimentary sequence of the epicontinental basin, wherein one was the depositional diastem developed between the facies, which was a discontinuous combination of the depositional facies with continuous time sequence, namely the exposed sediments, the tidal flat swamp and the peat swamp, and the shallow marine sediments appeared from bottom to top; and the other was the continuous sequence with gradually evolved sedimentary environment, in which it was a continuous process that the tidal flat swamp turned gradually into the peat swamp.
研究表明:陆表海盆地充填沉积序列中有两种较为典型的相组合,一是相与相间发育沉积间断面,为不连续沉积相组合,但在时间序列上是连续的,即自下而上依次为暴露沉积、潮坪沼泽及泥炭沼泽、浅海沉积;第二种序列是连续相序,盆地的环境演化是渐变的,潮坪沼泽化逐渐泥炭沼泽化是一个连续过程。

Because of a high groundwater level and a strong erosion action, the coal formed in a low peat swamp is great in gelatification index and in groundwa ter index, which are in a negative correlation to the ratio of clean coal recove ry. While for the high peat swamp, IG and IGW are small, corresponding to a high ratio of clean coal recovery.
低位泥炭沼泽由于潜水位较高,水流对泥炭沼泽表面的改造和冲刷作用较强,形成的煤层具有较高的凝胶化指数和地下水流动指数,并且与精煤产率呈负相关,煤中粘土矿物和黄铁矿难以洗选;高位泥炭沼泽形成的煤层具有较低的凝胶化指数和地下水流动指数,泥炭积累速度较快,其精煤的产率较高。

The research of marsh initiated in the 1960s in our country. However, the study of marsh sedimentation and environmental changes was relatively weak, even though we have done some preliminary works on an approach to the characteristics of sporepollen assemblage of peat in the Holocene and paleoenvironmwent, and formation mechanism and deposition kinetics of peatland since 1990s. But we are lacking in systematic research on gleying marsh, especially on recent short timescale and highresolution sedimentation records of environmental changes. There is a certain disparity in this field compared with lake sedimentation and environmental changes.
