摘　　要：造成热水成矿流体大规模迁移的机理有地壳的伸展、挤压、旋转伸展与旋转挤压。盆地中同生断裂是热水成矿流体迁移和传输的通道，沉积盆地是其沉淀和定位的场所，盆地的反转是矿床保存的条件。Largescale migrating mechanisms of oreforming hydrothermal fluids,include extension,compression,rotational extension and rotational compression at the earth crust.Synsedimentary faults in the sedimentary basin are passages of migrating and transfering for oreforming hydrothermal fluid, while the sedimentary basin is the place for precipitation and location of oreforming hydrothermal fluids.Deposits are well covered by reversing of the sedimentary basin.The characterization of geodynamics of the sedimentary Basin in Zashan,is also studied in the paper.
