2. Quartz monzonite - Wikipedia

   en.wikipedia.org/wiki/Quartz_monzonite

   Quartz monzonite. Quartz monzonite is an intrusive, felsic, igneous rock that has an approximately equal proportion of orthoclase and plagioclase feldspars. It is typically a light colored phaneritic (coarse-grained) to porphyritic granitic rock. The plagioclase is typically intermediate to sodic in composition, andesine to oligoclase.

   Countertop. A stainless steel countertop. A countertop, also counter top, counter, benchtop, worktop ( British English) or kitchen bench ( Australian or New Zealand English ), bunker ( Scottish English) is a raised, firm, flat, and horizontal surface. They are built for work in kitchens or other food preparation areas, bathrooms or lavatories ...

4. Engineered stone - Wikipedia

   en.wikipedia.org/wiki/Engineered_stone

   Engineered stone is a composite material made of crushed stone bound together by an adhesive to create a solid surface. The adhesive is most commonly polymer resin, with some newer versions using cement mix. This category includes engineered quartz (SiO 2 ), polymer concrete and engineered marble stone. [ 1]

5. Crystal habit - Wikipedia

   en.wikipedia.org/wiki/Crystal_habit

   Crystal habit. In mineralogy, crystal habit is the characteristic external shape of an individual crystal or aggregate of crystals. The habit of a crystal is dependent on its crystallographic form and growth conditions, which generally creates irregularities due to limited space in the crystallizing medium (commonly in rocks ). [ 1][ 2]

6. Quartz reef mining - Wikipedia

   en.wikipedia.org/wiki/Quartz_reef_mining

   Quartz reef mining. Quartz reef mining is a type of gold mining in "reefs" ( veins [ 1]) of quartz . Quartz is one of the most common minerals in the Earth's crust, and most quartz veins do not carry gold, but those that have gold are avidly hunted by prospectors. In the shallow, oxidized zones of quartz reef deposits, the gold occurs in its ...

7. Quartz inversion - Wikipedia

   en.wikipedia.org/wiki/Quartz_inversion

   The room-temperature form of quartz, α-quartz, undergoes a reversible change in crystal structure at 573 °C to form β-quartz. This phenomenon is called an inversion, and for the α to β quartz inversion is accompanied by a linear expansion of 0.45%. This inversion can lead to cracking of ceramic ware if cooling occurs too quickly through ...
