摘要
雪峰古陆是华南重要的金成矿区带之一．该区金矿的成矿物质来源一直是一个颇有争议的问题。在野外系统调研的基础上．笔者从稀土元素、微量元素以及同位素（Pb、S、Sr）地球化学角度，探讨了湘西南金矿床的成矿物质来源。研究表明，该区金矿的成矿物质主要来自赋矿围岩而非中基性脉岩，即赋矿地层为金的矿源层。
The Xuefeng ancient land is an important gold-producer in South China. However. up to now, no agreement has been reached on the metallogenic material source of gold deposits in thisarea. Based on systematical field investigations and REE, minor elements and isotope geochemistry, the gold deposits in southwestern Hunan are comprehensively studied. It can be revealedthat the ore-forming materials mainly come from the wall rocks rather than from the intermediatebasic dykes, j. e. .the ore-hosting strata is gold sourced.
