| 摘 要： | 本文根据《广西大瑶山西侧泥盆系铅锌黄铁矿床控矿条件及成矿预测研究》成果,按照沉积演化观点,将本区层控矿床成固类型划分为成岩矿床、成岩—后生矿床和后生矿床。成矿物质主要来源于赋矿地层下泥盆统及基底岩石,成矿溶液主要为大气降水经深循的渗流热卤水,成矿物质的聚集与成岩后生作用有关,矿床的形成可分为沉积、成岩、后生三个阶段,并建立了成矿模式。

| Abstract: | This paper is based on the reseach project The Controls and Minerogenetic Prognosis of Devonian Pb-Zn-Pyrite Deposits in Western Dayaoshan, Guangxi. According to the evolution of sedimentation, the strata-bound deposits in this area can be grouped into three genetic types, ie,, diagenetic deposit and diagenetic-epigenetic deposit, and epigenetic deposit. The ore-forming materials are mainly derived from the Sipai Stage (Lower Devonian) and the basement, whereas the ore-forming solutions are hot brine produced by meteoric water Circulating deep in the earth. The enrichment of the ore-forming materials are related to epigehetic processes. The ore deposits may have formed during three stages: deposition, diagenesis, and post-diagenesis. This paper also sets up a metallogenic model for ore deposits of this type. |
