本文以地洼学说为指导,从地球化学特征的研究入手,对花岗岩类小侵入体含矿性进行对比评价。 对比研究了郴县两个邻近岩体的地球化学特征,它们都是地洼花岗岩类小侵入体。著名的东坡矿田与千里山岩体有关,其矿化特征与各期次岩浆活动的关系,可作为湖南地洼花岗岩的典型。王仙岭岩体以前研究较差。千里山比王仙岭,硅碱质增加,Al_2O_3、铁镁总量和基性组分减少,矿化元素含量达到高峰,特别是锡、锌、铅、钇等。王仙岭则富钨、铋、砷、铍等,尤以硼、氧丰度为高。由于它们地化特征上的显著性差异,认为不属同一母体。王仙岭岩体较早,再加上侵入的围岩、构造位置及剥蚀程度等不同,其矿化特征和成矿远景也将相异。
In this paper, Diwa theory as a guide, starting from the study of geochemical characteristics of the granite-type small intrusions contain comparative evaluation. The geochemical characteristics of two adjacent rock masses in Chenxian are comparatively studied, all of which are small intrusion granites in Diwa. The famous Dongpo ore field is related to the Qianlishan rock mass. Its mineralization characteristics and the relationship between the magmatic activities of various phases can be regarded as typical of the Diwa granite in Hunan Province. Wang Xianling rock was poorly studied. In Qianlishan than Wangxianling, the contents of silicate increased, while the contents of Al 2 O 3, Fe and Mg reduced and the content of mineralized elements peaked, especially tin, zinc, lead and yttrium. Wang Xianling is rich in tungsten, bismuth, arsenic, beryllium, etc., especially boron, oxygen abundance is high. Because of their significant differences in geochemical characteristics, they are not considered as the same mother. Wang Xianling earlier rock mass, coupled with the invasion of the surrounding rock, tectonic location and degree of denudation, the mineralization characteristics and mineralization prospects will vary.
