Comparative Analysis on characteristics of Chemistry between Scandium Anatase Deposit in Qinglong Shazi and Laterite Gold Deposit in Western Guizhou, China

摘要

With scandium anatase deposit of Qinglong Shazi and three typical laterite gold deposit of Laowanchang, Baozidong and Shaguochang in western Guizhou as research objects, this paper makes a comparative analysis on characteristics of geochemistry between scandium anatase and gold deposit:1) The main oxides in the scandium anatase deposits and laterite gold deposits are similar, both of which include SiO_2, Al_2O_3 and Fe_2O_3 and its features are similar with that of laterite weathering crust in the contemporary age; 2) There are large differences of TiO_2 content in the scandium anatase deposits and laterite gold deposits with the TiO_2 content is much higher in the former one of 3.42-5.03%. 3) Both the scandium anatase deposits and laterite gold deposits have gone through the intense weathering and the complete oxidization; 4) Both the scandium anatase deposits and laterite gold deposits are argillaceous ore, while Laowanchang lateritic gold mines and Baozidong lateritic gold mines are featured with silty clay-based; 5) Baozidong's equals to 10.21-14.13 with the average value is 12.17; which indicates the enrichment of the light rare earth. This obviously reflects the differences of the ore-forming environments. 6) According to the analysis result of correlation of trace elements of scandium anatase deposits of Qinglong Shazi, it can be seen that related elements can obviously be divided into two groups with the correlation coefficient above 0.6: Au-Ag-As-Sb-Hg-Tl group and Sc-TiO_2-Cu-Fe-Mn group.
