湘西北下寒武统镍-钼多金属富集层镍与钼的赋存状态
STUDY ON NICKEL AND MOLYBDENUM MINERALS IN Ni-Mo SULFIDE LAYER OF THE LOWER CAMBRIAN BLACK ROCK SERIES,NORTHWESTERN HUNAN
【摘要】 对湘西北三岔、杆子坪镍-钼富集层中镍-钼矿石进行了电子探针研究,发现了镍黄铁矿、辉砷镍矿、方硫镍矿、针镍矿、紫硫镍矿与铁辉砷镍矿等镍的独立矿物与“碳硫钼矿”等含钼的矿物。研究表明,镍-钼富集层中镍主要赋存在上述含镍矿物及细粒胶状黄铁矿中;钼主要以“碳硫钼矿”的形式存在。
【Abstract】 In this paper,several nickel minerals such as pentlandite,gersdorffite,millerite,vaesite;violarite,Fe-bearing gersdorffite and a C-Mo-S mixed-layer phase(MoSC) have been detected from the Ni-Mo ore of the Sancha and Ganziping Ni-Mo sulfide layers,northwestern Hunan,on the basis of electron microprobe analyses.Moreover,it is the first time that violarite and Fe-bearing gersdorffite have been found from the Ni-Mo ores of this area.
