摘要
通过研究分步用HCl和HF除去含泥灰岩中碳酸盐矿物和泥质矿物之后所释放出来的有机质,发现这些与矿物结合的有机质和自由态有机质,在组成和分布上都有所区別。各类生物标志物的分布变化情况表明,不同矿物对有机质演化所起的作用不同,不同系列的有机化合物受矿物的影响也不一致。
The bitumen fractions obtained by stepwis extraction in conjunction with stepwise dissolution of carbonate and subsequently silicate minerals separated from limestone samples were examined, revealing differences between mineral-bound organic matter and free organic matter both in composition and in distribution. Variations in the distribution of biomarkers in the bitumen fractions provide strong evidence suggesting that the effects of carbonate minerals on the evolution of organic matter are differen from those of silicate minerals and that different mineral matrices would exert different effects on the evolution of organic matter of different types.
