本文对4块标样和4块现代生物及自然刻面作品的可溶有机物进行显微荧光光谱的测量分析表明:标样的荧光,随着苦环数的增多,λmax向长波移动;浮游植物、石孔莼等水生生物光谱峰在兰区,马尾范藻、柽柳叶等陆生植物光谱峰在红区;利用物质原始有机质的差异,用氯仿A的λmax与干酪极腐泥组关系图,可以进行生油岩类型的划分.

The microfluorometric analysis of soluble organic matter from four standard samples and four modern organism and natural section samples in this paper shows that heax moves towards the long-wave direction with the increase of aromatic ring numbers in the fluorescence of standard samples. The spectrum peaks of pIant plankton, Ulva and other hydrobios are in the blue area, and those of Sargassum and other genobenthos are in the red area. By meang of the correlation diagram of chloroform "A"λ Anax to kerogen sapropels combined with the difference of promal organic mater, the types of source rock can be classified.
