  • Feldspar - Wikipedia

    Feldspars are a group of rock-forming tectosilicate minerals that make up about 41% of the Earth's continental crust by weight. Feldspars crystallize from magma as both intrusive and extrusive igneous rocks and are also present in many types of metamorphic rock. Rock formed almost entirely of calcic plagioclase feldspar is known as anorthosite. Feldspars are also found in many types of sedimentary

  • Hematite - Wikipedia

    Hematite, also spelled as haematite, is a common iron oxide with a formula of Fe 2 O 3 and is widespread in rocks and soils. Hematite crystals belong to the rhombohedral lattice system which is designated the alpha polymorph of Fe 2 O 3.It has the same crystal structure as corundum (Al 2 O 3) and ilmenite (FeTiO 3), with which it forms a complete solid solution at temperatures above 950 °C

  • Feldspar Distinctions, Characteristics & Identification

    10-08-2019· Alkali feldspar (also called potassium feldspar or K-feldspar) has a color range from white to brick-red, and it's typically opaque. Many rocks have both feldspars, like granite. Cases like that are helpful for learning to tell the feldspars apart. The differences can be subtle and confusing.

  • Hematite and K-feldspar dissolution rates in an

    Hematite reaction rates range from 2.94x10-14 to 6.69x10-13, several orders of magnitude faster than those for K-feldspar. Calculated mineral dissolution rates are used to build a simple model including mineral dissolution-precipitation, advective-diffusive transport and trace metal adsorption.
