The beds, rich in organic material from which hydrocarbons originated, are called source beds . 富含能够产生碳氢化合物的有机物质的地层叫做生油层。
Fluorescence is high in shallow immature samples and decreases in the main zone of oil generation . 浅处未成熟样品的荧光是高位，而主要生油带则降低。
These molecules usually have a sufficiently characteristic distribution to permit differentiation between individual source beds and crude oils . 通常这些分子具有特征分布足以鉴别各自的生油层和原油。
The basinal location of such build-ups places reservoirs in proximity to source beds, and so commonly forms hydrocarbon accumulations . 这种生物建造的盆地位置，使储集层贴近于生油层，因此往往形成烃类聚集。
Identification of source rocks by quick methods, and quantitative evaluation of their petroleum potential can be done either in the laboratory or on the well-site . 无论在实验室或井场都能用快速方法鉴别生油岩并对其生油能力作出定量估价。
