The forward analysis of source rocks is defined as a method to estimate the amount of depositional organic matter or burial organic matter, and ulteriorly to estimate their original potential of hydrocarbon generation of source rocks by using the information of sedimentary environments, features of living biomass and physical chemistry in water medium through the geobiological analysis of geoecology, geomicrobiology, molecular geobiology and biogeochemistry. Quality and quantity of depositjonal organic matter can be calculated according to the productivity and preservation environrnents.

Sixty-nine years ago today, a ghost word was outed from its hiding place on page 771 of Webster's New International Dictionary, where it had spent five comfortable years. Dord started life on a slip of paper prepared by the lexicon's chemistry editor, who noted that "D or d" was an abbreviation for density. A serendipitous misinterpretation saw the entry being read as a single word, dord, and it was accordingly registered and printed up as a noun with the meaning "density." No proofreader caught the error, but five years later an editor noticed the word had no etymology and began the investigation that led to the word's being banished.
六十九年前的今天,一个谜一样的词被世人发现,这个词在韦伯斯特新国际字典的771页整整藏了5年Dord一词因为一张小纸片而开始了它的生涯,这张小纸片是由lexicon的化学主编准备的,他标注出了"D or d"是密度的缩写这条记录很偶然的被认为是一个完整的单词,dord之后它被作为一个名词收入词典并印刷出来,意思是"密度"所有的校对人员都没有发现这个错误,但是五年后,一名编辑注意到这个词没有词源,然后他开始溯源并最终将这个词从词典中去除
