河北兴隆平泉地区花岗岩类地球化学特征

本文通过大量实际资料,对兴隆平泉地区花岗岩类岩石化学、部分金属元素、微量元素及稀土元素分布等进行分析,主要论述了该区与成矿有关的两类岩石即花岗岩-花岗斑岩类及花岗闪长岩类岩石的地球化学特征,指出两类岩石在地球化学特征上的差异不仅与岩性有关,而且主要与成矿物质来源有关。

Geochemical Features of the Granites in Pingquan District, Xinglong, Hebei

Based on large amounts of data, this paper makes an analysis of the petrochemistry, ngnferrous metals, trace-element and the REE distribution of the granites in Pingquan district of Xinglong. This study deals mainly with the geochemical characteristics of two types of rocks related to minerahzation in this district, i. e., granite-granite porphyry and granodiorite. The paper points out that the geochemical difference between these two types of rocks is mainly related to the origin of their rockforming materials, beside their different petrological characters.
