| 摘 要： | 利用XRD，XRF，ICP－MS，结合电子探针与显微镜镜下观察，查明了该矿石的矿物成分组成、化学成分组成及钼元素的赋存状态。矿物成分为黄铁矿、辉钼矿，脉石矿物为石英、长石，含有少量方解石、白云石。钼元素的赋存状态主要跟硫元素形成辉钼矿，与黄铁矿共生。两者以侵染状嵌布在石英、长石脉石矿物中。辉钼矿以独立矿物形式存在，有少量的钼华呈星点状分布在脉石矿物中。

| Abstract: | XRD, XRF, ICP-MS, was used and combined with electron probe microscope to identify the mineral composition of the ore composition, chemical composition and mode of occurrence of molybdenum. Minerals are pyrite, molybdenite, gangue minerals are quartz, feldspar, contain small amounts of calcite and dolomite. Molybdenum occurs with sulfur to form the main molybdenite, and pyrite. Whichever form disseminated infection in quartz, feldspar gangue minerals. Molybdenite mineral form an independent existence, there was a small amount of molybdite punctate distribution in the gangue minerals. |
