有机烃在预测隐伏金矿床中的应用及其成因探索

在国内外许多热液矿床的成矿作用研究中都发现有烃类组分的存在，这一现象已越来越受到矿床学家的关注。有机质、有机烃与金属成矿作用之间存在着直接或者间接的成因关系。有机烃指标应用于金属矿产勘查和深部隐伏矿体的预测是一个尚处于试验阶段的新的研究领域，其基础理论还不十分成熟。本文从有机烃预测隐伏金矿床的应用实例着手，归纳出金矿体上有机烃异常特征和模式，并对异常来源以及异常模式成因进行探讨，结果表明有机烃异常特征和有机烃组分间相关特性能有效反映深部隐伏金矿体的赋存空间和成矿规模，为利用有机烃预测隐伏金矿寻求更坚实的理论基础。

Appl ication for Hydrocarbon in Prognosis Buried Gol d Deposits and Impl ication for Genesis

It had been more focused that the hydrocarbon was found in country rocks, minerals and their enclusions in many hydrothermal deposits. Hydrocarbon was the important product from organic matter during the development of fluid flow. It was just in a fore-research region that using hydrocarbon for mineral exploration or forecast on buried ore deposits, the basic theory of this kind research was only in the phase of experimentation and need to be improved. The research work based on a lot of gold deposits had been done. It was found that the anomalous model of hydrocarbon on gold deposits was contacted with immiscible fluid phase of fluid flow. Scatter plot maps of heavy--light hydrocarbon from different geological body in some gold deposits also give showing for the ore-forming background, metallogenic factors and epoch. These work were helpful for basic-theory researchs of application for hydrocarbon in prognosis buried gold deposits.
