| Abstract: | The K-feldspar vein-type gold deposit fault zone tracing veins at south-north direction. in this report is controllea by a tenso-snear The industrial type of gold ores is of individual gold and the dominant gangue mineral is pink-colored K-feldspar. Minerals bearing gold is of pyritohedron pyrite and limonite, with which gold presents in native gold, enclosed gold, fissure-filling gold and intergranular gold. The ore-hunting indicator is of calcite-potassium feldspar veins containing pyritohedron pyrite. |
