摘要
本文从地层岩性、岩相古地理、岩浆演化分异、包裹体测温、稳定同位素、物质来源和矿床定位机制、成岩成矿概念模式诸方面,论证了矿田系“层、相、位、源、障”等成矿有利条件有机结合的产物。
In terms of the lithologic characters of stratigraphic strata, facies and paleogeography of sedimentary rocks, the differentiation and evolu ion of magma, temperature measurement of inclusions in minerals, analysis of stable isotopes, sources of mineralization materials, mechanism of the deposit emplacement and the concept models of rock formation nd mineraliztion, etc., this paper concludes that Yaogangxian orefield is the common product of five factor: “stratigra hic strata, sedim ntary f cies, structural positions, sources of mineralization ma e ials, and geochemical barrier wh ch are the most favourable and intimat conditions for the formation of the deposit.
