Willman reported astrophyllite, biotite, molybdenite, and riebeckite associated with smoky quartz and microcline on Mount Kineo at North Cheyenne Canyon. |
At the Redskin mine, molybdenite is found in small cylindrical greisen pipes in the Redskin Granite. |
In the deposits of New South Wales they are found associated with molybdenite in quartz gangue, in pipe-like deposits in granite. |
At Azegour, Morocco, uraninite occurs in tactite with molybdenite, chalcopyrite, barite, pyrite, hematite, and garnet. |
When it rises through fractures in the surrounding solid rocks, these metals are precipitated, normally as the minerals chalcopyrite, bornite, and molybdenite. |
The researchers have revealed that molybdenite, or MoS2, is a very effective semiconductor. |
