通常认为,石油和天然气完全是生物成因的。正因此,它们常被称为“化石燃料”。然而自1960年以来,一些科学家先后提出,某些碳氢化合物是具非生物成因的。今天,说明存在非生物成因有机物(主要是甲烷)的证据很多。 1.微包体岩石矿物流体包体研究提供了大量有关流体温度、压力及组成的数据。1974年,J.图雷在对认为形成于康拉德面和莫霍面之间的麻粒岩内的流体包体进行研究时发现,包体内均存在着含量达百分之几(微量—10%)的碳氢化合物,其中主要有甲
It is generally believed that oil and gas are completely biologically responsible. Because of this, they are often called “fossil fuels.” However, since 1960, some scientists have proposed that certain hydrocarbons are abiotic causes. Today, there is much evidence of the existence of abiotic organisms (mainly methane). 1. Microencapsulations Rock mineral-fluid inclusions studies provide a wealth of data on fluid temperature, pressure, and composition. In 1974, J. Toure studied fluid inclusions in granulites that are believed to be formed between the Conrad and Moho, and found that inclusions contained up to a few percent (trace-10 %) Of the hydrocarbons, mainly A
