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.
