Thermoelectricity Characteristics of Pyrite from Xincheng Gold Deposit,Eastern Shandong
摘要
Abstract
Xincheng gold deposit, located in the Jiaojia gold field of Eastern Shandong, is a super-large altered cataclastic rock type gold deposit. Pyrite is recognized as the most important gold-bearing mineral in this deposit. Combined with thermoelectricity characteristics of pyrite from different depths and exploration lines of Xincheng gold deposit, the spatial distribution regularities of thermoelectric conductive type of pyrite, the mineralization temperature and the denudation rate of ore body are discussed in this paper, and we proposed the prospective ore area in the deeper areas. Research shows, compared to N-type (less than 30% ), the thermoelectric conductive type of pyrite of Xincheng gold deposit is mainly P-type (70. 20% ) , whose thermoelectric coefficient is 180 to 320 μV · ℃-1 and - 180 to - 80 μV ·℃-1 respectively; the variation trend of thermoelectric conductive type is P→N from shallow to deep areas; mineralizing temperature centers on 180 to 340 ℃ , which indicates that it is a mesothermal deposit; denudation rate of ore body is 49. 98%. Combined with the field geological study and the data in this paper, three ore prospective areas are proposed: depth below - 630 m from 149 to 157 and from 181 to 193 exploration lines, and depth below -730 m from 161 to 179 exploration lines.关键词
