| 摘 要： | 以二长花岗岩类为主体的锡田岩体，分布在南岭花岗岩套北部边缘，形成时代为燕山早期。岩石具有高硅、富碱以及W，Sn，Mo，Bi，Cu和U，Th丰度高的特点。与湘南地区的骑田岭、香花岭等含Sn花岗岩体特征有相似之处，具有找W，Sn矿的较好潜力。岩石地球化学综合研究表明，其具有典型的后造山(post-orogenic。)作用形成的“A型花岗岩”类岩石的地球化学特征，从而显示锡田岩体形成时该区处于陆壳开始拉张裂陷的构造背景。

| Abstract: | The Xitian granite pluton located in the northern margin of Nanling erogenic belt is mainly composed of monzogranite which was formed during early Yanshanian period and are characterized by high in silicon and rich in alkali with high contents of tungsten, tin, molybdenum, bismuth, copper, uranium and thorium. The Xitian granite pluton lithochemically resembles the tin-bearing Qitianling and Xianghualing plutons in southern Hunan and shows excellent potential tungsten-tin mineralization. Geochemically, the Xitian granite pluton shows the characteristics of typical post-orogenic A-type granite and might be formed in a intraplate extensional setting. |
