Abstract

Abstract

Xiejiagou gold deposit, discovered in 2002, is located in the southwest of Zhaoyuan City, Shandong Province.The detailed study of macroscopic and microscopic perspectives of ores in Xiejiagou gold deposit reveals two types of gold-bearing ores: primary ores and oxidized ores.The primary ores, classified as pyritization and sericitization-silication granite, chalcopyritization-pyritization and sericitization-silication granite, multi-sulfide and sericitization-silication granite, and chalcopyrite-pyrite quartz vein, are located at different positions in the brittle-ducility shear-zone, reflecting 2 periods and 5 stages of metallization process.The gold occurred mainly in gold inclusion, between minerals and in cracks.The average gold fineness is 859.96 in gold inclusion, 843.83 between minerals, and 833.08 in cracks, respectively, indicating that the gold mineralization occurred in the middle and deep layers and that the temperature of mineralization decreased gradually from the gold inclusion, between minerals and in crack.
