Alkali feldspar granite Wikipedia

Alkali feldspar granite, some varieties of which are called 'red granite', is a felsic igneous rock and a type of granite rich in the mineral potassium feldspar (K-spar). It is a dense rock with a phaneritic texture. The abundance of K-spar gives the rock a predominant pink to reddish hue; peppered with minor amounts of black minerals.

Alkalic Granite Florida State University

Though primarily composed of quartz and feldspars, granite also frequently contains small amounts of hornblende, micas, and other minerals. Moreover, the proportion of plagioclase to alkali feldspar may differ in granite samples, which is often utilized as the starting point for granite classifications.

Additional observations on the dissolution of alkali feldspars come from studies by Fenter et al. [100–102] and Teng et al. [103] of orthoclase dissolution on the (001) and (010) cleavage surfaces, which used atomic force microscopy and synchrotron X-ray reflectivity (Figure 7.3(a)).These studies found that the measured X-ray reflectivity did not decrease

Alkali Feldspar: Mineral information, data and localities.

A subgroup of the Feldspar Group, poor in calcium, and mostly rich in potassium.It is mostly used in petrology for the high temperature series from sanidine to high albite; the series is incomplete at low temperature, but normal albite, orthoclase and microcline are generally still included as alkali feldspars. Some workers (eg the Strunz classification) include barium feldspars (celsian and

Feldspar Wikipedia

In addition, peristerite is the name given to feldspar containing approximately equal amounts of intergrown alkali feldspar and plagioclase. Barium feldspars. Barium feldspars are also considered alkali feldspars. Barium feldspars form as the result of the substitution of barium for potassium in the mineral structure.

lar alkali-feldspar segregated from the porphyritic granite that typically occur in the vicinity of microgranular enclaves (Fig. 2c); this association suggests segregation of solid material within the mush, probably caused by the introduction of hotter magma. Felsic segregations (mostly alkali-feldspar accumulations) are also associated with

Granite Wikipedia

Granite (/ ˈ ɡ r æ n ɪ t /) is a coarse-grained igneous rock composed mostly of quartz, alkali feldspar, and plagioclase.It forms from magma with a high content of silica and alkali metal oxides that slowly solidifies underground.It is common in the Earth's continental crust, where it is found in various kinds of igneous intrusions.These range in size from dikes only a few inches across to

Perthite mineralogy Britannica

Perthite, any member of a class of alkali feldspars in which tiny crystals of sodium-rich feldspar (albite; NaAlSi 3 O 8) are intimately intergrown with, but distinct from, tiny crystals of potassium-rich feldspar (orthoclase or, less commonly, microcline; KAlSi 3 O 8).Slow cooling of a homogeneous, molten mixture of sodium and potassium feldspar induces instabilities and results in the

Feldspar mineral classification: This ternary diagram shows how feldspar minerals are classified on the basis of their chemical composition. The sequence of minerals along the left side of the triangle represents the solid solution series of the alkali feldspars. The sequence along the base is the solid solution series of the plagioclase feldspars.

Granite: Igneous Rock Pictures, Definition & More

Granite is a plutonic rock in which quartz makes up between 10 and 50 percent of the felsic components. Alkali feldspar accounts for 65 to 90 percent of the total feldspar content. Applying this definition requires the mineral identification and quantification abilities of a competent geologist.
