What are the types of feldspar?

There are broadly three main types of feldspars: calcium, sodium and potassium. They have the following general chemical formulas:KAlSi3O8 - NaAlSi3O8 - CaAl2Si2O8The endmember mineral states are known as K-Feldspar, Albite and Anorthite which are the potassium, sodium and calcium feldspars respectively.There can be a mix of calcium and sodium (more correctly termed solid solutions) in Feldspars between Albite and Anorthite which are known generally as Plagioclase feldspars.For more information please see the related question

Which mineral is most frequently found in both granitic continental crust and basaltic oceanic crust?

The mineral most frequently found in both granitic continental crust and basaltic oceanic crust is feldspar. Feldspar is a common mineral found in igneous rocks and is a major component of both types of crust due to its abundance and widespread distribution.


What is andesitic magma made of?

Andesitic magma is composed of a mixture of silica-rich minerals such as plagioclase feldspar and amphibole. It also contains smaller quantities of pyroxene, biotite, and quartz. Its intermediate composition gives it characteristics of both basaltic and rhyolitic magmas.


Where is feldspar found in NC?

Feldspar is found in North Carolina primarily in the Spruce Pine Mining District, which is located in the western part of the state. This area is known for producing high-quality feldspar, including both potassium feldspar and plagioclase feldspar. The feldspar from this region is used in various industries such as ceramics, glassmaking, and abrasives.


Compare and contrast granite and diorite?

Contrast: Granite consists mainly of quartz, feldspar, and ferromagnesian ("dark") minerals Diorite may be incorrectly called "granite". Diorite contains virtually no quartz, no muscovite, and no K-feldspar. It also contains a higher percentage of dark silicate minerals. Diorite has a salt and pepper appearance. Compare: Both granite and diorite are phaneritic (course-grained) rocks. Diorite is primarily sodium- rich plagioclase feldspar and amphibole, with lesser amounts of biotite. On other minor constituents of granite include muscovite and some dark silicates, particularly biotite and amphibole.


What type of feldspar contain either sodium or calcium?

Both sodium and calcium can occur with a variety of other metallic elements or silicon. Perhaps you would like to review the wikipedia article about feldspar.


How many different elements are in potassium and nitrate?

Potassium and nitrate both contain one type of element each. Potassium contains the element potassium (K) and nitrate contains the elements nitrogen (N) and oxygen (O).


Potassium sulphate and potassium sulphate both contain potassium and?

Well, first off, you list the same substance twice but potassium sulfate contains potassium, sulfur, and oxygen.


Compare the mineral composition of diorite with the mineral composition of andesite?

Both andesite and diorite are igneous rocks with an intermediate color index. Diorite; however, is intrusive and phaneritic, whereas andesite is aphanitic and extrusive. Andesite is said to be the extrusive equivalent of diorite. Diorite is made up of plagioclase feldspar and ferromagnesian mineral crystals, mainly amphibole. Contrarily, andesite may resemble rhyolite, meaning it presents a need for microscopic examination to see its mineral crystals. The two have a composition of plagioclase feldspar and amphibole, but it is much more difficult to detect in andesite.
