Scheelite Mineral Properties, Photos and Occurrence</h3>Crystal StructurePhysical PropertiesOriginApplicationsOccurrenceScheelite is a calcium tungstate mineral that is the dominant member of a solid solution series between tungstenrich scheelite (CaWO4) and rare molybdenumrich powellite (CaMoO4), a much less common variant. This solid solution explains why most scheelites contain certain amount of molybdenum in their structure. Scheelite crystallizes in the tetragonal system, often forming as tetragonal dipyramids which look like octahedrons. Additionally, it may be tabular, massive, granular or columnar, sometimes as grai
