| 摘 要： | 成煤原始物质的堆积方式分为2大类型:原地堆积——腐植煤的原始物质聚集在泥炭沼泽中植物自身繁殖的地方;异地堆积——腐植煤的原始物质是从相邻地区或大陆更远的一些地段,经过搬运,聚集在淡水盆地、泻湖、三角洲、湖泊之中.从煤与底板岩石的关系、煤物质的纯度、化石的完整程度等方面,分析了成煤物质的堆积条件,认为在煤层形成过程中,原地堆积方式起主导作用.

| Abstract: | There are two types of coal formation: a) local land accumulation in which the original substance of rotten plant material congregates in a peat bog where plants are growing; b) distant land accumulation in which the original substance, which is from nearby areas or somewhere distant, of rotten plant coal congregates in a fresh water basin, lagoon, delta or lake through movements. Coal formation conditions are interpreted through the study of the relationship between coal and footwall rocks and the quality of coal and fossil integrity. The conclusion is that local land accumulation is the dominant process in coalbed formation. |
