摘要
本文通过微量元素、硫同位素、氧同位素及矿物流体包裹体研究等方法首次对宁夏海原西华山地区金矿化的地球化学特征进行了探讨，提出了地层、构造及岩浆活动三者联合控矿的成因认识。这一认识无疑对宁夏为数不多的有色金属矿化区之一──宁夏海原西华山地区的金矿的找矿预测具有实际意义。
in this paper, the geochemical characteristics of the gold mineralization in Xihua mountains,Haiyuan, Ningxia Autonomous Region are discussed for the first time accordillg to the microelements, sulfur and oxygen isotopes and the fluid inclusions. It is suggested that the strata, the tectonism and the rnagmatism control the gold mineralization together. This conclusion is of practical significance in predicting and prospecting the gold deposits in this district.
