摘      要：The geotectonic units of Zhejiang Province include the Yangtze Plate in the northwest juxtaposed against the South China fold system in the southeast along the Jiangshan-Shaoxing *** South China fold system is further divided into the Chencai-Suichang uplift belt and the Wenzhou-Linhai geotectogene belt,whose boundary is the Yuyao-Lishui *** corresponding metallogenic belts are the Mo-Au(-Pb-Zn-Cu) metallogenic belt in northwest Zhejiang,the Chencai-Suichang Au-Ag-Pb-Zn-Mo metallogenic belt,and the coastal Ag-Pb-Zn-Mo-Au metallogenic *** main Mesozoic metal ore deposits include epithermal Au-Ag(Ag),hydrothermal vein-type Ag-Pb-Zn(Cu),and porphyry-skarntype Mo and vein-type Mo *** ore bodies are related to the Mesozoic volcanic-intrusive structure:the epithermal Au-Ag(Ag) deposits are represented by the Zhilingtou Au-Ag deposit and Houan Ag deposit and their veins are controlled by volcanic structure;the hydrothermal vein-type Ag-Pb-Zn deposits are represented by the Dalingkou Ag-Pb-Zn deposit and also controlled by volcanic structure;and the porphyry-skarn-type Mo deposits are represented by the Tongcun Mo deposit and the vein-type Mo deposits are represented by the Shipingchuan Mo deposit,all of which are related to granite porphyries. These metal ore deposits have close spatio-temporal relationships with each other;both the epithermal Au-Ag(Ag) deposits and the hydrothermal vein-type Ag-Pb-Zn deposits exhibit vertical zonations of the metallic elements and form a Mo-Pb-Zn-Au-Ag metallogenetic *** Jurassic-Cretaceous deposits may be products of tectonic -volcanic-intrusive magniatic activities during the westward subduction of the Pacific *** metallogenetic conditions and breakthroughs in the recent prospecting show that there is great resource potential for porphyry-type deposits(Mo,Cu) in Zhejiang Province.
