沉积岩石中广泛分布有一定数量的有机质,它们与许多重要的沉积矿产在成因上有着密切的联系。有机体进入沉积物之后,在沉积岩成岩作用的过程中发生了一系列的变化,即有机质演化。有机质演化影响到一些沉积矿产,如石油、天然气、煤、煤成烃类以及某些层控金属矿床的形成与勘探评价。作者试图根据我所有机地球化学与沉积地球化学研究室近年来部分研究结果与兄弟单位的资料,从有机质演化观点出发探讨这些沉积矿产的成因。全文拟分两部份,本文着重讨论石油与天然气的成因与评价,特别是与我国
The sedimentary rocks are widely distributed with a certain amount of organic matter, which is closely related to the genesis of many important sedimentary minerals. After the organisms enter the sediments, a series of changes occur in the diagenesis of sedimentary rocks, that is, the evolution of organic matter. The evolution of organic matter affects the formation and exploration evaluation of some sedimentary minerals such as oil, natural gas, coal, hydrocarbonaceous hydrocarbons and some stratiform metallogenic deposits. The author attempts to explore the causes of these sedimentary mineral deposits from the perspective of the evolution of organic matter based on the data from some of our research results in recent years in all of the geochemical and sedimentary geochemistry laboratories of our institute. The full text is divided into two parts, this article focuses on the causes and evaluation of oil and natural gas, especially with our country
