On the ore-forming conditions and ore-forming model of the superlarge multimetal deposit in Shizhuyuan

Eight favorable ore-forming conditions for the Shizhuyuan W-multimetal deposit are proposed. They are: (i) the geochemistry background special enriching the volatile and W and Sn ore-forming elements; (ii) the existence of melt-fluid system very rich in volatile and ore-forming elements; (iii) supply of sufficient ore-forming material and volatile multi-source; (iv) the infiltration and convection water source and driving force partly supplied by the Jurassic reservoir basin; (v) favorable tectonic conditions; (vi) ore-bearing greisen and vein superimposed in the pre-existing skarn rocks; (vii) favorable ore-transport and ore-concentration strata condition; (viii) there were a set of favorable ore-forming structures in Shizuyuan area; (ix) the orebody has good ore-reserve condition. Finally, ore-forming models are proposed. The paper is one of the achievements on the research related to the Climbing Project “The basic related to searching for the superlarge deposits supported by the State Science and Technology Commission. This research is also granted by the National Natural Science Foundation of China (Grant No. 49572134).
