Discovery and significance of scheelite orebodies in the Zhaishang gold deposit, southern Gansu

Abstrate：Located in the western part of the Min-Li metallogenetic belt, wetern Qinling Mountains, the Zhaishang gold deposit is a recently discovered large Carlin-type disseminated gold deposit. Examination of ores by optical microscope, EPMA and ICP-MS from the the deposit, has revealed a scheelite enrichment. On the basis of chemical-analytical data, several independent scheelite orebodies are located. It belong to Au-Sb-W deposit association of gold-scheelite-stibnite. In some ways, it can be compared with the Manaoke gold deposit in Sichuan with respect to geological setting, host lithology, mineralization style, mineral assemblages, geochemical association and metallogenic processes involved. Since in the Devonian and Triassic strata in the triangular border region of Sichuan， Gansu and Shaanxi provinces， as so-called golder trangle， coith many gold deposits or occurrences similar to the Zhaishang deposit，it is obviously of great importance to evaluate the value of tungsten and other elements in these gold deposits.
