| 英文摘要 | The Yemaquan gold deposit is located in Yemaquan block of eastern Junggar. The dominant strata within the area are Silurian low-grade metamorphic carbonaceous clastic rocks. Orebodies occur in fractured and altered diorite-porphyry dyke and its sheared contact wallrocks. The dominant alterations related to gold mineralization are silicification, sericitization and arsenopyrite-pyritization. Data on REE, fluid inclusion and isotopes show that the Yemaquan gold deposit is genetically associated with diorite magmatism. The ore-forming fluid mainly originates from the magma differentiation, which released gold-bearing fluid phase, when the diorite magma digested pyrite-bearing carbonaceous wallrock. U-Pb concordant ages of 252.5 +/- 1.8Ma and 254.5 +/- 0.9Ma from zircon of gold mineralized diorite-porphyry are corresponding with the last tectonic-magmatic-mineralization stage of post-collision in the northern part of Xinjiang. Similar gold deposits are widely distributed in the Junggar and its adjacent area. These deposits possess transitive characteristics between structurally-controlled gold deposits and intrusion-associated type. Thus, they may classified to be a new (sub-) type of gold deposits: structurally-controlled-altered-dyke type. |
