中文摘要：

通过对黑龙江省金厂金矿床内包裹体的研究,对比不同矿化程度岩石中包裹体特征,认识到矿化程度与岩浆-流体的演化程度有密切的关系。矿化主要为黄铁矿化,还见有黄铜矿、方铅矿、闪锌矿、毒砂等硫化物矿物,主要呈脉状、条带状及浸染状产出。矿化程度高的钻孔岩芯内,包裹体类型发育完整,流体包裹体、熔融包裹体、熔-流包裹体均有发现。进一步研究发现,矿化与岩浆的结晶分异作用、流体的沸腾作用及流体的混合作用关系密切。分异作用使成矿物质得到富集,沸腾与混合作用使矿质进一步富集并沉淀析出。

英文摘要：

Based on a study of fluid inclusions in the Jinchang gold deposits of Heilongjiang Province and a comparison of characteristics of inclusions in rocks with different mineralization intensities, the authors hold that the mineralization intensity is closely related to the evolution degree of magma and fluid. Mineralizations include mainly pyritization as well as some other sulfides such as chalcopyrite, sphalerite and arsenopyrite, assuming veinlike, banded and disseminated forms. Inclusions are well-developed ih highly-evolutionary rocks, composed of fluid inclusions, melt inclusions and melt-fluid inclusions. Further studies indicate that mineralization has intimate relationship with magmatic fractional crystallization, fluid boiling and fluid mixing. Fractional crystallization concentrated metallogenic elements, which precipitated under the conditions of boiling and fluid mixing.
