WebApr 2, 2024 · According to the mineralogical composition, the Xu-3 Member can be divided into two petrological types, namely clayey fine-grained felsic sedimentary rocks and lime fine-grained felsic sedimentary rocks. The main mineral components are siliceous, clay, and carbonate minerals. WebThe mafic rocks also typically have a higher density than felsic rocks. The term roughly corresponds to the older basic rock class. Mafic lava, before cooling, has a low viscosity, in comparison with felsic lava, due to the …
WebMar 13, 2024 · Felsic magma has the highest silica content of all magma types, between 65-70%. As a result, felsic magma also has the highest gas content and viscosity, and lowest mean temperatures, between 650° and … WebMafic rocks contain minerals with less silica, but more iron and magnesium. Mafic rocks (and therefore ocean crust) are denser than the felsic rocks of continental crust. The crust floats on the mantle. Continental crust floats higher in the mantle than ocean crust because of the lower density of continental crust.
WebThe continental crust has an average density of 2.7 g/cm 3 and is composed primarily of felsic rock. Felsic rock is rich in light elements such as silicon, aluminum, oxygen, sodium, and potassium. The presence of these lighter elements is responsible for continental crust being slightly less dense than oceanic crust, which has an average ... WebQuestion 7. 30 seconds. Q.
