Jul 25, 2017· Potassium Feldspar minerals are renowned for their intriguing opalescence. Moonstone, which is a perthite of sodium and potassium aluminosilicate, is characterized by an attractive silvery or bluish iridescence.

Jun 25, 2018· Sand comes from many locations, sources, and environments. Sand forms when rocks break down from weathering and eroding over thousands and even millions of years. Rocks take time to decompose, especially quartz (silica) and feldspar.

Large quartz (gray) crystals in alkali feldspar pegmatite. Nyelv, Norway. Width of view 50 cm. St. Peter Sandstone from the Ordovician Period is composed of almost pure and wellrounded quartz grains. Sand from this formation is widely used for fracking purposes. Width of view 20 mm.

What is common to all the feldspars is the same arrangement of atoms, a framework arrangement, and one basic chemical recipe, a silicate (silicon plus oxygen) recipe. Quartz is another framework silicate, consisting only of oxygen and silicon, but feldspar has various other metals partly replacing the silicon.

Polycrystalline quartz of sand size, especially if more than five individual crystals are present, is a better indicator of a metamorphic source. Milky quartz is not very common in sandstones, but when it does occur it is likely an indicator that the quartz was derived from a pegmatite or vein quartz.

Quartz sand is also added to molten metals so that it bonds with impurities which then can be easily removed. Quartz sand is also used in beaches, baseball arenas, golf courses, volleyball courts, as well as children's sand boxes and also employed for traction purposes in rail tracks and mines.

Apr 25, 2017· Feldspar is the principle ground mineral of granite, monzonite and syenite. It makes up approximately 60percent of these igneous rocks and gives granite its porphyritic texture (a mix of large grains with intersticial smaller grains). Feldspars are further divided into two types.
