关于黔西南微细浸染型金矿床成因的一些初步认识

以黔西南金矿床与莫霍面隆起、深大断裂、岩浆岩体、航磁异常、重力异常、环形构造及地热场的时空对应关系为线索，讨论了深源流体参与金矿成矿的可能性。铅、硫、氢、氧同位素地球化学研究表明，成矿物质来源于深源流体及地层岩石。金矿床是上升热流体改造地层岩石的产物。

SOME ASPECTS OF UNDERSTANDING IN GENESIS OF THE FINE DISSEMINATED GOLD DEPOSITS IN SOUTHWESTERN GUIZHOU PROVINCE

According to the corresponding relations in time and space between gold deposits and some aspects like uplift of Moho,deep faults,magma intrusions,aeromagnetic anomaly, gravity anomaly, circular structure and geotherm fields, the possibility of gold mineralization participated by deep fluid has been discussed. Studies of Pb,S,H,O isotope geochemisty indicate that the mineralization resources were from deep source fluid and rocks of the strata.Gold deposits were resulted by the uplifting thermal fluid to reform the strata.
