中文摘要：

邓阜仙钨锡多金属矿床位于南岭多金属成矿带中段的一个重要石英脉型黑钨矿矿床。本文尝试采用与钨矿成矿关系密切的长石、石英开展了He—Ar与H-O同位素的研究，结果显示石英流体包裹体的3He/4He测定值为0．006～0．0244Ra，明显低于地壳值（0．01～0．05Ra）。成矿流体中40Ar/36Ar变化范围在303．3～867．8，高于饱和大气雨水。40Ar/36Ar值（295．5）。石英包裹体中，δ18O测试值变化于＋10．3‰-＋13．7‰之间，平均为＋12．4‰；石英中包裹体H2O的δD测试值变化于-72．9‰--100．1‰之间，平均为-89．28‰，表明成矿流体为岩浆水与大气降水的混合。两种不同的同位素体系均表明本区的成矿作用为邓阜仙岩体的期后热液受到了裂隙中大气降水的影响。

英文摘要：

Dengfuxian Sn-W polymetallic deposit is located in the middle of the multi-mineral belt in Nanling. The 3He/4He of the quartz fluid inclusions measured value is between 0.006 Ra and 0.0 244 Ra, below the earth＇s crust（0.01 - 0.05Ra） . The 40Ar/36Ar variation range of ore-forming fluid is between 303.3 and 867.8,shows the atmospheric precipitation hybrid. δ18O of the quartz fluid inclusions measured value is＋ 10.3‰ and ＋ 13.7‰ ;δD in the quartz fluid inclusions measured value is between-72.9‰and- 100.1‰, average value is -89.28‰ ,indi- cates that the ore-forming fluid is a mixture of magmatic water and meteoric water.
