中文摘要：

为揭示赣南荡坪钨矿的成矿流体特征及矿床成因,采用流体包裹体组合的研究方法,利用红外显微镜、冷热台和激光拉曼等测试手段,对黑钨矿和与其共生的石英中流体包裹体进行了系统的岩相学观察、显微测温及成分分析。结果表明,与黑钨矿形成相关的流体为中高温、中低盐度的NaCl-H_2O流体体系,与石英中流体包裹体相比,黑钨矿中包裹体的总体均一温度及盐度较高,分布范围狭窄,表明黑钨矿与共生石英中的流体包裹体形成的p-t-x条件不同。成矿流体在演化过程中的冷却作用是本矿床黑钨矿沉淀成矿的主要因素。

英文摘要：

In order to reveal characteristics of the ore-forming fluid and genesis of the Dangping quartz-type tungsten deposit in southern Jiangxi,this study has adopted the concept of Fluid Inclusion Assemblage（ FIA） and performed systematically detailed petrographic observation,microthermometry and component analysis of fluid inclusions in wolframite and intergrown quartz in quartz veins by using infrared microscope,cooling-heating stage and laser Raman spectroscopy. We found that the fluid in association with the tungsten mineralization is a Na Cl-H2 O fluid with medium to high homogenization temperatures and medium to low salinities. Compared to the fluid inclusions in quartz,those in wolframite have relatively high homogenization temperatures and salinities varying in very narrow range. It shows that the P-T- X conditions for the formation of wolframite are different to that of the intergrown quartz. In addition,it is proposed that that the cooling of fluids is mainly caused the precipitation of tungsten in the evolution process of the ore-forming fluid.
