Granite is a light-colored igneous rock with grains large enough tobe visible with the unaided eye. It forms from the slow crystallization of magma below Earth's surface. Granite is composed mainly of quartz and feldspar with minor amounts of mica,
amphiboles, and other minerals.
The mineral-bodies of the two mineral deposits are mainly existed inthe contacting zone of granite-porphyry and adjoining rock.

In geology, felsic refers to igneous rocks that are relatively rich in elementsthat form feldspar and quartz.[1] It is contrasted with mafic rocks, which are relatively richer in magnesium and iron. It refers to thoserocks rich in silicateminerals, magma, and rocks which are enriched in the lighterelements such as silicon, oxygen, aluminium, sodium,and potassium.
Theyare usually light in color and have specificgravities less than 3.The most common felsic rock is granite.Common felsic minerals include quartz,muscovite, orthoclase,and the sodium-rich plagioclase feldspars. In terms of chemistry,felsic minerals and rocks are at the other end of the elemental spectrum fromthe mafic minerals and rocks.

gneiss 英 [naɪs] 美 [naɪs]
n.片麻岩
[例句]
Gneiss [naɪs] is called bastard granite.
片麻岩叫作粗花岗岩.
Gneiss is a high grade metamorphic rock, meaning that it has beensubjected to higher temperatures and pressures than schist. It is formed by themetamorphosis of granite, or sedimentary rock. Gneiss displays distinct foliation, representingalternating layers composed of different minerals.
Gneiss [naɪs] /ˈnaɪs/ is a common and widelydistributed type of rock formed by high-grade regional metamorphic processesfrom pre-existing formations that were originally either igneous ['ɪɡniəs] or sedimentaryrocks.

Granite is a common rock that contains at least 25% quartz and is sometimes used in construction because of its strength.
