地史上由生物死亡后变成的各种有机物质会遭到各种地质作用的改造,尤其是热液活动、岩浆侵入、放射性元素蜕变以及构造变动等地质因素所引起的热能,会使矿床中(主岩中)的有机物出现成熟异常现象。通过对某些层控矿床中有机物质的研究,可以解释成矿物质的来源、沉淀富集机理、含矿热液运移路线和主岩的沉积环境,并且可以指示矿体的大致分布范围,指导找矿勘探。
In the history, all kinds of organic substances that have been changed from living creatures to death will be transformed by various geological processes. In particular, the thermal energy caused by geologic factors such as hydrothermal activities, magma intrusion, radioactive element metamorphism and structural alterations will cause the mineral deposits (Host rock) organic matter mature abnormal phenomenon. Through the study of organic matter in some stratabound ore deposits, the origin of ore-forming materials, sedimentary enrichment mechanism, migration path of ore-bearing hydrothermal fluids and sedimentary environment of host rock can be explained, and the general distribution of ore bodies can be indicated. Guidance exploration prospecting.
