广西贺州福安银多金属矿两类石英脉地质地球化学特征对比研究
Contrastive study on geological and geochemical characteristics of two types of quartz veins in Fu’an silver polymetallic deposit, Guangxi
摘要
Abstract
According to 1:2000 geologica1 survey and the tectono-geochemical prospecting work in the study area,the authors summed up the mineral composition, occurrence, morphology , size and occurring location of two types of quartz veins. The statistical analysis of trace element parameters show thatⅠ- type quartz vein are rich in iron group elements such as Cu, Pb, Zn, W, Mn, Mo, Sn, Ag, Co, As, Sb, Bi, Au andⅡ-type quartz veins are rich in iron group elements such as Cr, Ni, V, Ti. Cluster analysis and correspondence analysis show thatⅠ-type quartz vein is close to the ore-forming process and a multi-stage mineralization; Ⅱ-type quartz vein have some degree of post-mineralization event superimposed. REE analysis show that lower total REE content and differen-tiation is weak inⅠ-type quartz vein, indicating that formed in the deep source of hydrothermal magmatic;Ⅱ-Type quartz vein characteristics with LREE, suggesting that which from the surrounding rock belong to tectonic bedding foliation.关键词
