中文摘要:本文以新田岭钙矽卡岩型自钨矿床为例，通过硫、碳、氢、氧稳定同位素研究所获得的成矿信息，探讨了矽卡岩白钨矿床的成因和物质来源。矿区氢氧同位素组成表明成矿溶液属以岩浆水为主的混合岩浆水，后期变为大气降水；碳主要来源于地层碳，混有岩浆碳；硫源为深源硫与地层硫的混合。稳定同位素结合地质年代学研究，表明该矿床系与燕山早期黑云母花岗岩有关的接触交代型矿床，钨主要来源于大陆地壳重熔化岗岩浆热液。
Abstract:The information of metallization obtained from sulfur, carbon, hydrogen and oxygen isotopic studies of minerals and rocks from the ore district in combination with the geologic investigation indicates the contact metasomatic origin of the deposit, provides grounds for petrogenic and ore-forming material sources, and gives interpretation on formation process and evolution of the deposit in the light of geology and geochemistry. The δD values of water in fluid inclusions of quartz in metallogenic period range from -43 to-5 5‰. δ18O values of scheelite from 3.6 to 7‰, δ18O values of quartz from 11.4 to 14.3‰, and calculatedδ18OH2O values from 4.7 to 7‰, suggesting an origin of magmatic water mixed with meteoric water. Theδ13C values of calcite in metallogenic period vary from -3.5 to -6.8‰, and δ18O from 10.4 to 11.5‰, showing the domination of strata-derived carbon mixed with some magmatic carbon. The sulfur source as indicated by isotopic study seems to be a mixture of magmatic and strata sulfur. The quartz-magnetite pair gives a metallogenic temperature of some 698℃, while the quartz-scheelite pair shows 322-344℃.On the basis of these data, combined with geologic study, it is believed that this deposit is a skarn type scheelite one associated with early Yanshazaian biotite granite, with tungsten derived from and concentrated in hydrothermial solutions of granitic magma formed by remelting of the continental crrut.
