How are basalt and granite diffrerent in their origin texture and mineral composition How are the similar?

Basalt is extrusive, formed from cooling lava, and has a fine-grained texture with minerals like pyroxene and plagioclase feldspar. Granite is intrusive, formed from cooling magma underground, and has a coarse-grained texture with minerals like quartz, feldspar, and mica. Both are igneous rocks, but basalt is dark-colored and dense, while granite is light-colored and less dense.


What type of rock would result from the metamorphism of granite?

The metamorphism of granite would likely result in the formation of gneiss, a coarse-grained foliated rock with distinct bands of minerals. The high temperature and pressure during metamorphism would cause the minerals in the granite to recrystallize and align, giving gneiss its characteristic banded appearance.


If a mass of granite is in contact with a layer of sandstone that contains small pieces of the granite which rock is older?

The granite would be older because it had to form first in order for the sandstone to contain pieces of it. The sandstone would have formed later on top of the granite layer.


What is the density of granite chippings?

Granite chippings are granite aggregates that are primarily composed of feldspar and used as paving material. The density of granite chippings is 166.5 lbs / ft3 .


Is granite homogenous or heterogenous?

Granite is a heterogeneous material, meaning it is composed of a variety of different minerals that are visible to the naked eye. This gives granite its characteristic speckled appearance.
