The second data column lists this number as a percentage of all minerals listed with Tungsten. The first data column contains the total number of minerals listed with Tungsten and the element listed for that row. Note that unlike other sections on this page this includes non-essential elements. This table compares the known valid mineral species listed listed with Tungsten and the other elements listed based on the official IMA formula. L07 MinorĮlement association of Tungsten in the Mineral World W porphyry: Stockworks of scheelite and/or wolframite in quartz veins and veinlets in felsic intrusive rocks and associated rocks. Ore body shapes are stratiform, tabular and lens-like.

Usually in rocks that were originally an impure limestone that were intruded by granitic rocks.

I12* W skarns: Consists primarily of scheelite in contact metamorphic rocks. Major W veins: Consists of wolframite bearing quartz veins in igneous rocks, primarily granites. W 4+ is enriched in Ca-Al-rich inclusions in meteorites relative to the composition of the solar system.Ītom mole fraction relative to Si=1 (% uncertainty) Wikipedia WebElements Los Alamos National Laboratory Theodore Gray's Ĥ7 valid species containing essential Tungsten Fausto Elhuyar Juan José Elhuyar and Fausto Elhuyarįrom the Swedish and Danish: "tung sten" - "heavy stone"
