STUDY ON ORE-FORMING GEOCHEMISTRY OF COPPER-GOLD-SILVER-POLYMETAL METALLOGENIC ZONE IN PUCHENG-SANDU’AO, FUJIAN

本文校系统地研究了成矿元素及微星元素．稀土元素和铅、硫、氢、氧同位素等成矿地球化学特征．研究结果表明，研究区内成矿物质来源是多方面的；成矿过程中的介质水在成矿主要阶段是大气降水与再平衡岩浆水的混会，在成矿晚期则主要来自大气降水；成矿是多阶段的，可依据各阶段的矿化程度来确定今后应侧重的矿种．

ore-forming geochemistry characters of metallogenic and trace elements, REE and lead, sul-fur, hydrogen and oxygen isotope are Studied in rather detuils. The results of studies above showthat ore-forming materials are from many sources in discussed area, and that the water medium inore-forming process is the mixture of atmospheric water and magmatic water in main metallogenicStuge and is chiefly the atmospheric water in the late stage, and that ore sort further wil1 be empha-sised depending on the minerallization degree of certain stages in the area.
