| Western Junggar mineralization is an important part of the Central Asian region, with a complex tectonic structure and evolution history. Qi ⅠHatu gold mine is the largest gold mine in Western Junggar region, prospecting and exploration in recent years has made significant progress: the discovery of new ore body at 500 ~ 900 m deep, and did not see the signs down pinch, show gold deep mining industry ore possibility exists, while recognizing that the distribution of the ore body controlled by faults.1. The main guide ore structure of gold mineralization is main fault of NE, the secondary fault of NE, EW and NW faults are the main ore controlling structures. The fault between Hatu and Anqi which is conducive to the preservation.2. The distribution characteristics of mining rock showed variation of sedimentary environment on the side: lack phase environment in the west; In the central region is interaction of continental and lack facies; The Middle East is mostly continental volcano dominated; East near the volcano, the main form of thick basalt-thin tuff formation.3. The whole group to the east tilt of L27 ore vein, the three main ore veins along the lateral trending direction from shallow to deep distribution for L27, L27-8 and L27-14. According to the known ore controlling faults and veins echelon distribution characteristics, there may be other veins along the deep of tilt direction, they will appear at the junction of Anqi fault and EW fault of control the L27 vein group distribution, and to expand.4. The EW trending faults group in the vicinity of the Anqi fault which gradually changed to the NEE, according to studies of zircons’ SHRIMP age of diabase show that the fault formation of these dikes and ore veins are not the same age, which the result of multi-stage activities of Anqi fault.5. The age of gold mineralization and Granite Emplacement ages are basically the same. Magmatic hydrothermal metal rich elements associated with granitic magma flow along the Anqi fracture. In the migration process, Hydrothermal and Lower Carboniferous volcanic-sedimentary occurs water-rock reaction, and extraction of metal ore-forming elements. According to the characteristics of the migration, the sketch map of the Hatu gold deposit metallogenic model is established. |
