摘要
Abstract
This paper used inductively coupled plasma mass spectrometry (ICP-MS)to determine the concen-tration of rare earth elements (REE)and the composition of ore and surrounding rocks of Pb-Zn deposit from Xiaba,Guangxi Province,and discussed the geochemical characteristics and the source of ore-forming fluid of the deposit. The results show that the total rare earth content is quite low,ranging from 0.5 1 ×10 -6 to 36.53 × 10 -6,while LREE/HREE is about 3.06 to 6.05.In different types of ore body,the content and distribution patterns of REE vary in a quite wide range,and negative anomaly for Ce and both positive and negative anomaly for Eu are presented in the samples. Combined with the REE parameters and geological features of the ore,it can be deduced that the metallogenic fluid source of Xiaba deposit is a hybrid of ore-bearing brine and deep cir-cling underground water under special physical-chemical condition.关键词
