摘要
Systematic ore mineralogy research shows that the Taiyangshan gold deposits ore minerals are mainly composed of pyrite, pyrrhotite, silver-bearing native gold, sphalerlite and chalcopyrite, etc. The wall-rock alterations include silicification, sericitization, kfeldsparization, graphitization and migmatization, etc. The ores have euhedralsubhedral-pseudomorphic crush texture, poikilitic texture, pressure texture, feint texture and offset texture, and have impregnated structure, vein structure and net vein structure. The geological characteristics are extremely similar to the Jiaojia gold deposit of typical altered tectonite-type gold in Shandong province. Consequently, the Taiyangshan gold deposit is a typical altered tectonite-type gold ore deposit.
