Granite is felsic
Granite forms from silica-rich (felsic) magmas. Felsic magmas are thought to form by addition of heat or water vapor to rock of the lower crust, rather than by decompression of mantle rock, as is the case with basaltic magmas. It has also been suggested that some granites found at convergent boundaries … See more Granite is a coarse-grained (phaneritic) intrusive 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 cools and solidifies … See more Granitic rock is widely distributed throughout the continental crust. Much of it was intruded during the Precambrian age; it is the most abundant basement rock that underlies the … See more Physical weathering occurs on a large scale in the form of exfoliation joints, which are the result of granite's expanding and fracturing as pressure is relieved when overlying material … See more Granite and related marble industries are considered one of the oldest industries in the world, existing as far back as Ancient Egypt See more The word "granite" comes from the Latin granum, a grain, in reference to the coarse-grained structure of such a completely crystalline rock.

WebGranite is an example of a felsic intrusive rock, while gabbro and diabase are examples of mafic intrusive rocks. Sedimentary rocks are formed by the gradual consolidation of organic or inorganic solid fragments, carried by, suspended in, or dropped by wind, water, or ice and deposited horizontally in layers.

WebFeb 28, 2024 · Apatite Sr-Nd and zircon Hf-O isotopes are broadly used to trace magma sources and constrain magma evolution processes, further improving our understanding of the origin of granitoids. We present zircon U-Pb ages, whole-rock major and trace elements, and whole-rock Sr-Nd-Hf, zircon Hf-O, and apatite Sr-Nd isotopic data for the coarse … WebApr 12, 2024 · In the past, magmatic differentiation was thought not to produce resolvable Li isotopic fractionation based on studies of basaltic rocks. Overall, only sparse studies on Li isotopes of highly evolved granites have been reported, and thus possible isotope fractionation of Li isotopes during differentiation of felsic magma could have been …

Granite is an intrusive igneous rock composed primarily of feldspar, quartz, and smaller amounts of mica. It has a phaneritic texture, meaning that individual crystals can be seen with the naked eye. Because of its relatively high quartz and feldspar content, granite tends to be light in color (felsic). the north and south poles of the earth areIn geology, felsic is a modifier describing igneous rocks that are relatively rich in elements that form feldspar and quartz. It is contrasted with mafic rocks, which are relatively richer in magnesium and iron. Felsic refers to silicate minerals, magma, and rocks which are enriched in the lighter elements such as silicon, oxygen, aluminium, sodium, and potassium.
