| 摘 要： | 通过显微镜鉴定、电子探针（EPMA）及X射线粉晶衍射法等方法,首次对温泉钼矿的矿物组合、矿石类型、矿石结构构造和钼的赋存状态进行了研究。结果表明,矿石矿物为中温热液成因,并受温泉斑岩体的控制;钼矿物主要为辉钼矿。辉钼矿的多型为2H型（六方晶系）,为自形—半自形,呈细小鳞片状、片状、板条状分布于岩石中;辉钼矿的粒度主要集中在0.08-0.16 mm粒级范围,占总量的51.65%;黄铁矿中钼含量较高,且形成越早钼含量越高。 |
| 关 键 词： | 西秦岭 温泉钼矿床 辉钼矿 矿物特征 赋存状态 |

| Abstract: | In this paper, mineral association, ore type, ore texture, ore structure and occurrence states of the Wenquan Molybdenum deposit in Wushan Gansu have been analyzed for the first time by methods such as microscopic identification, electron probe( EPMA), X - diffraction crystal powder analysis and so on. Ore mineral controlled by Wenquan porphyritic rockbody is originated from mesothermal hydrothermal. Essential minerals are 2H-type molybdenite (hexagonal system) and idiomorphic-subhedral with shapes of scale-like, flake-like, and lath-like. Molybdenite with granularity from +0.08mm to 0.16mm occupies 51.65% of the total molybdenite. Pyrite has high content of molybdenum, the sooner of its formation time, the higher of its molybdenum content. |
