摘　　要：黑钨矿和白钨矿是钨矿床中重要载钨矿物。本文对较为罕见的钨锰矿和钼钨矿开展原位激光拉曼光谱测试分析,旨在探讨Mn元素和Mo元素对黑钨矿及白钨矿结构的影响。结果显示:钨锰矿出现882cm^(-1)、773cm^(-1)、696cm^(-1)、695cm^(-1)、544cm^(-1)、540cm^(-1)、394cm^(-1)、323cm^(-1)、325cm^(-1)、256cm^(-1)、204cm^(-1)、202cm^(-1)以及126cm^(-1)的拉曼活性峰,且位于540cm^(-1)、544cm^(-1)的峰是该钨锰矿所特有,推测其可能为识别钨锰矿的特征峰,特征峰的出现可能与该矿物中较高Mn含量有关。普通白钨矿拉曼谱峰位于112cm^(-1)、207cm^(-1)、328cm^(-1)、366cm^(-1)、397cm^(-1)、429cm^(-1)、637cm^(-1)、692cm^(-1)、795cm^(-1)、834cm^(-1)、906cm^(-1)、1108cm^(-1)与1185cm^(-1)处;钼钨矿的拉曼谱峰位于1183cm^(-1)、1110cm^(-1)、913cm^(-1)、878cm^(-1)、839cm^(-1)、792cm^(-1)、692cm^(-1)、636cm^(-1)、392cm^(-1)、324cm^(-1)、202cm^(-1)以及106cm^(-1)处。1108cm^(-1)与1113cm^(-1)处的峰可能为识别钼钨矿的主要特征峰,Mo元素的加入也可能会使得白钨矿中部分拉曼位移发生偏移。Wolframite and scheelite are important tungsten-carrying minerals in tungsten deposits.In this paper,in-situ laser Raman spectra analysis was carried out to study the effects of Mn and Mo elements on the structure of wolframite and scheelite.The results show:Tungsten-manganese ore appears in Raman activity peak of 882 cm1,773 cm^(-1),696 cm^(-1),695 cm^(-1),544 cm^(-1),540 cm^(-1),394 cm^(-1),323 cm^(-1),325 cm^(-1),256 cm^(-1),204 cm^(-1),202 cm^(-1) and 126cm^(-1).Among them,the peaks at 540 cm^(-1) and 544 cm^(-1) are unique to the tungsten-manganese ore,and it is speculated that they may be the characteristic peaks to identify the tungsten-manganese ore,and the appearance of the characteristic peaks may be related to the high Mn content in the mineral.The Raman spectra of ordinary scheelite are 112 cm^(-1),207 cm^(-1),328 cm^(-1),366 cm^(-1),397 cm^(-1),429 cm^(-1),637 cm^(-1),692 cm^(-1),795 cm^(-1),834 cm1,906 cm^(-1),1108 cm^(-1) and 1185 cm^(-1);The Raman spectra of Mo-scheelite are 1183 cm^(-1),1110 cm^(-1),913 cm^(-1),878 cm^(-1),839 cm^(-1),792 cm^(-1),692 cm^(-1),636 cm^(-1),392 cm^(-1),324 cm^(-1),202 cm^(-1) and 106 cm^(-1).Among them,the peaks at 1108 cm^(-1) and 1113 cm^(-1) may be the main characteristic peaks for identifying molybdenum-tungsten ore,and the addition of Mo element may also shift partial Raman displacement in the scheite.
