摘要
The alteration zone is located in contact position between the lower part of the Late Proterozoic Qb Diaoyutai Formation quartz sandstone and the Late Archean metamorphic monzonitic granite, showing the fault contact relationship with the underlying metamorphic monzonitic granite, the gradational contact relationship with the quartz sandstone. The alteration zone appear intermittently, 10~mas-microsoft-com:office:smarttags" />20 m wide, 200~800 m long strike NE 50°~60°. The alteration mineral is mainly silicified quartz, a little baritization, sericitize, pyritization, chip analysis grade Au: 0.3x10-6. Its bearing strata, alteration mineral combination are similar to the large gold deposit, Jinying gold mine. By the comparative analysis, it is considered that the study area has the geological conditions of Jinying type gold mine, and better exploration prospects.
