| 摘 要： | 为了探讨赣南淘锡坑岩体与本区钨矿床的成因联系，对淘锡坑岩体进行了系统的地球化学分析.分析结果表明，淘锡坑岩体具有高Si、富Al、低Ti的特征，同时，岩体强烈亏损Eu、Ba、Sr等微量元素，富集Th、U等元素，岩体整体显示出与A型花岗岩相似的地球化学特征.这些地球化学特征暗示淘锡坑岩体整体具有良好的钨成矿性，是比较典型的富钨花岗岩，表明淘锡坑岩体对本区钨矿床的形成起了重要作用.

| Abstract: | Geochemical analyses are carried out on the Taoxikeng granite which is closely related to the economically important Taoxikeng tungsten deposit in Southern Jiangxi Province, South China. The results show that the Taoxikeng granites are characterized by high silicon and aluminum contents and low titanium content. The granites show strong depletion of Eu, Sr and Ba, and enrichment of Th and U. These geochemical characteristics resemble to those of A-type granite, showing well mineralization of tungsten. Combined with the regional data, the authors propose that granitic magmatism played an important role during tungsten mineralization, which provides ore-forming material source for the mineralization and further leads to the formation of Taoxikeng tungsten deposit. |
