Geology of Quartz Deposits - Mineralogical Society of America

4. Most of the deposits in bedrock are quartz veins, or flat-lying blanket deposits of milky quartz roughly parallel to the enclosing sediments, or a combination of these two types. The clear crystal usually occurs in vugs or pockets and appears to have formed later than the bulk of the milky quartz. 5.

Preliminary Model of Porphyry Copper Deposits

Porphyry copper deposits form in continental magmatic arcs along convergent plate-margin boundaries or in island-arc environments. The deposits are associated with subduction-related volcanic centers, although in some examples, they are thought to be associated with postcollisional volcanism. Permissive magmatic-arc environments may be ...

Research area: Quartz beneficiation - NTNU

Quartz, one of the most common minerals, is found all over Norway, some as deposits of relatively pure quartz, but mostly associated with other rock forming minerals. Generally quartz has been mined from the mono mineral deposits, although some quartz has been a secondary product when making feldspar from pegmatite and granites.
