摘要
湖南锡矿山超大型锑矿床是世界上已知最大的锑矿床,本文对该矿床矿区内唯一的岩浆活动显示——煌斑岩脉进行了较系统研究,研究表明该岩脉为幔源成因,结晶分异程度较低,其微量元素、稀土元素特征均表明锑矿床所在壳体的上地幔部分曾发生过广泛地幔交代作用,存在锑元素的富集。
The Xikuangshan stibnite ore deposit is the largest antimony deposit in t he world.A research has been carried out on the l amprophyre which occurred in the east part of the ore district and the research results sh ow that the lamprophyre is of mantle o rigin and its degree of crystallization is low.Moreover,the characteristics of the trace ele ments and REE indicate that the upper mantle of the crustobody in which the superlarge antimony deposit occurs has ex-perienced a pervasive mantle metaso matism,and has been enriched by antimony element.
