Information on Alkali feldspar granite - world of stones

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.

The alkali‐feldspar granite directly intrudes into the surrounding volcanic strata. Zircon U–Pb ages of the Awusiqi andesites, rhyolites, and alkali‐feldspar granite are 431 ± 3 Ma, 428 ± 5 Ma, and 426 ± 6 Ma, respectively. These new age data imply for the existence of Silurian magmatism in the Saur area. The alkali‐feldspar granite and rhyolites with high silica and alkali contents ...

Feldspar Distinctions, Characteristics Identification

2019-08-10  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. That's because the chemical formulas for the feldspars blend smoothly into each other. Feldspar ...

Amazonitic alkali feldspar from the Tanakami Granitic

However, much more studies on pegmatite feldspars are required to clarify a variety of pegmatite en-vironments and their formation processes. Amazonites, which are widely known as a blue-green variety of alkali feldspar (microcline or orthoclase), mostly occur in pegmatites (Cech et al., 1971; Hofmeister and Rossman, 1983, 1985; Smith and Brown, 1988; Deer et al., 2001).

Feldspar - Wikipedia

Feldspars (K Al Si 3 O 8 – Na Al Si 3 O 8 – Ca Al 2 Si 2 O 8) 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 ...

Feldspar minerals make up over 50% of Earth's crust.

The plagioclase feldspars form a solid solution series between the end members of pure albite (NaAlSi 3 O 8) and pure anorthite (CaAl 2 Si 2 O 8). The alkali feldspars form a solid solution series between pure albite and potassium sanidine (KAlSi 3 O 8). A list of feldspar minerals with their chemical compositions can be seen in Table 1.

Granite (s.s.) is a plutonic rock with a simple felsic mineralogy of quartz + alkali feldspar + plagioclase, with more than 20% quartz and plagioclase representing 10 to 65 vol% of total feldspar. In addition to granite, intrusive rocks with over 20 vol% of quartz are commonly referred to as ^granitoids _, and they share many characteristics with granites s.s. Granitoids span typically silica ...
