How long does it take for quartz to form?

Answer 1

Actually, quartz is one of the last minerals to cool under the surface. Because of this, the quartz tends to fill in all of the empty spaces in the solidfying magma, causing it to often come out in flakes, or oddly shaped chunks. Not all igneous rocks cool slowly, and this factor is just dependent on whether or not the rock is intrusive (still under ground) or extrusive (above or near the surface). Because obviously if a rock is underground, with all of the hot magma, it is going to take thousands of years for it to cool completely. While the air of the atmosphere that humans live in is way cooler than underground, so obviously it is going to take less time to cool it. So in closing, it just depends where the quartz is at in the Earth's crust. But, if it is in the Earth's crust, it usually is one of the last minerals to cool, making quartz unique.

Answer 2

That depends on the rate of cooling, which depends on temperature. This also affects crystal size. Also note that relative to other minerals, Quartz cools first on average, hence the large crystals in Granite.

Answer 3

it depends on what type it is and the structure and the way you make it grow all crystals never have the same growing time line

Answer 4

It takes about two weeks I am pretty sure.
