低熟煤中孢粉与可溶有机质的关系

根据孢粉分析和可溶有机质抽提后得到的数据,采用数理统计的方法分析了煤中的孢粉体与可溶有机质关系.结果表明：蕨类孢子含量与氯仿沥青“A”和非烃正相关,与饱和烃、芳烃则显著负相关,而裸子植物花粉则反之.这种情况说明尽管所有生物先质都有生烃作用,但对可溶烃贡献差别较大.而蕨类孢子和裸子植物花粉相比,可能对低熟-未熟油,特别是含非烃较高的低熟油有某种更为密切的联系.后者则可能与成熟-高成熟煤中才能释放出来的烃类物质更为密切.

Relationship Between Sporopollen and Soluble Organic Matters in the Low-Rank Coals

According to the data obtained from analysis of sporopollen and the soluble organism,the relationship between sporopollen and soluble organism was studied by mathematical statistics.The results show that the content of fern spore positively,but gymnospermae pollen negatively correlated to bituminous "A" and resin,which also indicate that,although all the former organism do have the ability of hydrocarbon generation,there are obviously differences of the contribution to the soluble hydrocarbon.Compared with gymnospermae pollen,the fern spore has a more closer relationship with soluble organism in the low-rank source rocks from the coal-bearing strata.However,the gymnospermae has a relatively closer relationship with hydrocarbon that was not generated in the source rocks from the coal-bearing strata.
