| 摘 要： | 佳木斯地块西缘金矿带的形成受左行走滑断裂带和深部流体控制，壳-幔作用和地球动力体制转换是成矿物质活化→运移→聚集→成矿的基本动力学保障，构造应力场转换是其重要表现形式。深切地幔牡丹江岩石圈断裂的活动发生了深熔作用，使成矿物质得以活化、运移的重要驱动力，是成岩成矿作用发生的根本原因之一。地幔流体通过壳-幔相互作用形成了含矿流体，为流体成矿作用提供了矿源，并沿深断裂运移到更高的层位，在物理化学条件发生改变时沉积成矿。佳木斯地块西缘金矿带是受深断裂控制的，矿床之间是相互联系的，是在一个构造应力体制下完成它们的成矿作用的。北北东向和伴生的北西西向断裂，并有中生代浅成-超浅成岩体或脉岩侵位是今后找矿的方向。

| Abstract: | Auriferous belt in western margin of Kiamusze massif is controlled by strike-slip fault belt and deep fluid. Transfer between Crust-Mantle reaction and dynamic system is the basic dynamic guarantee of activation to transportation to congregation to mineralization, transfer of tectonic stress field is its important manifestation. Activity of Peony River lithosphere fault which cut mantle occur anatectic process. This process activated and trans-fered the mineralized material, became main driver of them. The process is one of the roots that lithogenesis and mineralization occurred. Fluid in mantle becomes ore-bearing fluid by Crust-Mantel reaction, which provides mineral source for fluid mineralization, and transfers to higher stratohorizon through deep fault. The fluid is mineralized by deposition when the physical-chemical condition changed. Auriferous belt at western margin of Kiamusze massif is controlled by deep rupture, depositions are correlative. The auriferous belt' s mineralization is finished under same tectonic stress system. N-N-E and N-W-W correlated with it directional rupture and Hypabyssal-Supe-rhypabyssal rock mass are the directions that ore-search for the future. |
