Abstract—

The Koklan W–Mo deposit in Transuralia is confined to the eponymous Middle Permian leucogranitic pluton, which intrudes a sequence of the Lower Paleozoic crystalline schists with lenses of ultramafic rocks, marbles, and skarns. The economic stockwork W–Mo mineralization spans both outer and inner contacts of the pluton and is related to greisenization. The economic subdivision of ores is based on host rocks. The ores of granite and schist types (88.7% in total) are dominant in contrast to strongly subordinate ultramafic and skarn types. Molybdenum is mostly contained in molybdenite and, rarely, in scheelite. Tungsten is mainly related to scheelite; wolframite is extremely rare. The Mo and W contents of ores and rocks show no correlation. The major ore minerals are pyrite, molybdenite, and scheelite; subordinate minerals include chalcopyrite, pyrrhotite, and magnetite, and rare minerals are arsenopyrite, gersdorffite, nickeline, pentlandite, tetrahedrite, bornite, galena, native bismuth, bismuthinite, Bi sulfosalts, and uraninite.

Koklan W-Mo 矿床，Transuralia：矿物学-地球化学分区

摘要-

Transuralia 的 Koklan W-Mo 矿床仅限于同名的中二叠纪淡色花岗岩体，该岩体侵入了一系列下古生界结晶片岩，具有超镁铁质岩、大理岩和矽卡岩的透镜体。经济网状 W-Mo 矿化跨越岩体的外部和内部接触，与灰化有关。矿石的经济细分以主岩为基础。花岗岩和片岩类型的矿石（总共 88.7%）占主导地位，而超镁铁质和矽卡岩类型则处于次要地位。钼主要包含在辉钼矿中，很少包含在白钨矿中。钨主要与白钨矿有关；黑钨矿极为罕见。矿石与岩石的钼、钨含量无相关性。矿石矿物主要有黄铁矿、辉钼矿和白钨矿；次要矿物包括黄铜矿、
