Tungsten, tung′sten, n. a rare metal, chiefly derived from wolfram, which is a tungstate of iron and manganese, and likewise found in scheelite, which is a tungstate of lime.—n.

Not only the Paymaster with its tons of mined ore, but the ten claims to the north, all showing good scheelite, which Death Valley Charley had located–he had held them down as well.

In these occurrences the tungsten mineral is almost invariably scheelite, and is associated with calcite, garnet, pyroxene, and other silicates.

He had known it contained scheelite the moment he picked up that white rock that Virginia had placed in her collection, but naturally he had not announced it from the house-tops.
