It is the most plentiful mineral in Earth's surface. It is comprised of one part silicon and two parts oxygen. Its chemical classification is Silicate.]]> 2020-10-06 16:21:56 UTC https://padlet.com/jlsjackson85/tlg2bf0dqq01326o/wish/807381896 Rock Types and Where Quartz Occurs. jlsjackson85 https://padlet.com/jlsjackson85/tlg2bf0dqq01326o/wish/807459009 Quartz is present within igneous, metamorphic and sedimentary rock and is abundant all over the world . Its strength and resistence to weathering make it a dominant mineral of mountaintops and has a commanding presence in beach, river and desert sand.]]> 2020-10-06 16:39:00 UTC https://padlet.com/jlsjackson85/tlg2bf0dqq01326o/wish/807459009 Formation Environment and Process. jlsjackson85 https://padlet.com/jlsjackson85/tlg2bf0dqq01326o/wish/807517920 Quartz can form in different rock types as magma cools, the silicon dioxide crystallizes - slow cooling often generatets larger crystals. Quartz can also form in silica-rich waters in a very similar way but only with high temperature and high pressure. Once the temperature or pressure drops, quartz crystals form.]]> 2020-10-06 16:51:45 UTC https://padlet.com/jlsjackson85/tlg2bf0dqq01326o/wish/807517920 Reference List. jlsjackson85 https://padlet.com/jlsjackson85/tlg2bf0dqq01326o/wish/807628648 Quartz – A ubiquitous mineral with an enormous number of uses.

Quartz crystals can be used to make amazingly accurate time-keeping instruments and equipment that can transmit radio and television signals with stable frequencies. Quartz is used to make crystal oscillators for watches, clocks, radios, electronic meters and GPS equipment.]]> 2020-10-06 17:30:53 UTC https://padlet.com/jlsjackson85/tlg2bf0dqq01326o/wish/807702784 jlsjackson85 https://padlet.com/jlsjackson85/tlg2bf0dqq01326o/wish/807736705 Watch using a crystal oscillator.]]> 2020-10-06 17:38:18 UTC https://padlet.com/jlsjackson85/tlg2bf0dqq01326o/wish/807736705 Industrial and Commercial Uses. jlsjackson85 https://padlet.com/jlsjackson85/tlg2bf0dqq01326o/wish/807747080 Sand with high quartz content is used as a filler in the manufacturing of rubber, paints and putties, and can also be used for traction in railroad mining industries. ]]> 2020-10-06 17:40:36 UTC https://padlet.com/jlsjackson85/tlg2bf0dqq01326o/wish/807747080 Geographic Location. jlsjackson85 https://padlet.com/jlsjackson85/tlg2bf0dqq01326o/wish/807864095 Quartz is heavily abundant in the Earth’s crust and occurs in nearly all igneous, metamorphic and sedimentary rocks. It can also concentrate itself within sandstone and other detrital rocks. Quartz is found globally but is typically mined in the United states (Arkansas mainly) and Brazil. ]]> 2020-10-06 18:06:27 UTC https://padlet.com/jlsjackson85/tlg2bf0dqq01326o/wish/807864095
