| 摘 要： | 近年来脉金矿床在成因模式研究方面，有岩浆成因模式，变质模式、地幔去气—麻粒岩化和连续成矿模式等。并着重从成矿流体、矿质来源、沉淀过程和构造背景方面，探讨了脉金产出的地球动力学背景，控矿构造特征，煌斑岩（脉）与金成矿时空关系等。指出我国主要产于花岗岩中的脉金矿床，其流体来源性质，花岗岩中构造对成矿的控制作用，花岗岩的地球动力学背景是值得注意的研究课题。并指出应谨慎对待同位素测年资料。

| Abstract: | Recently,several models have come forward in studies of geneses of vein gold deposits:the model of magmatic genesis,the model of metamorphic genesis,the theory of mantle dehydration-granulization,and the model of continous metallogeny.In terms of ore-forming fluids,matter,origin,precipitation process and structural setting,this paper investigats the geodynamics,structural ore-controling features and lamprophyre-gold relations.It is shown by the author that special attention should be paid to studies of the origin and nature of fluids,the control of structures over mineralization and the geodynamics of granites for the vein gold deposits in granites in China,and chronlogical data of isotopes should be treated with doubt. |
