Comparative Analysis on genesis of mineral deposit between Scandium anatase deposit in Qinglong Shazi and Laterite Gold Deposit in Western Guizhou

This paper makes a comparative analysis on genesis of mineral deposit between Scandium anatase and laterite gold deposit in Western Guizhou, the study shows that: 1) High-gold source rock of laterite gold ore in western Guizhou is formed at the initial period of strong eruption of basalt in Mount Emei at the top of Maokou limestone; 2) The high-gold source rock is remaining in micro depressions at the erosion surface of paleokarst and is exposed or near to the superficial zone through later tectonic change. 3) Scandium anatase deposit of Qinglong Shazi is formed through basaltic volcanic breccia, volcaniclastic rock and tuff dropping into the water of paleokarst micro depression. Basaltic matters immerse and disintegrate titanium in rock which forms to anatase in low temperature and pressure and alkalescence water. 4) Through quaternary long-time evolution, surrounding rock changes into red clay and anatase is stored steadily in normal temperature and pressure. 5) With differences in micro-phase paleogeographic environment, eruption of basalt in Mount Emei and falling of pyroclasts in different environments lead to the differences of mineral element combination and formation of ore deposits of different mine types.
