指出，现今大量的地球化学资料证实，烃类在很大程度上是由天然的CO、CO2、H2在全球无机合成带的地质演化过程中形成的。
It is approved from a great number of geochemical data that hydrocarbons could be formed from co, CO2 and H2 in global inorganic synthetic zones by geologic evolution process to a great extent.
从无机地球化学角度看，研究段内自下而上水体逐渐变淡，酸性有所增强，酸性环境有利于有机质的成熟演化。
From inorganic geochemistry, the study results in this paper show that, the information water in the studied interval becomes fresh and its acidity becomes a little strong from the lower to the upper.
