What is the igneous rock that is dense and dark colored and forms from magma that is rich in iron and magnesium but poor in silica That has 8 letters?
The igneous rock you are referring to is basalt. It is a fine-grained, dense, and dark-colored rock that forms from low-silica magma rich in iron and magnesium.
This igneous rock is coarse-grained. The dark-colored mineral composing this rock is probably?
The dark-colored mineral in coarse-grained igneous rocks is likely to be biotite or hornblende. These minerals are commonly found in rocks like diorite, gabbro, and basalt.
Is dolostone a mineral or a rock?
Dolostone is a rock. Dolomite is the mineral often composing dolostone.
Why are mineral bands in metamorphic rocks light and dark colored?
Mineral bands in metamorphic rocks have light and dark colors due to differences in mineral composition and crystal structure. Light-colored bands may contain minerals like quartz and feldspar, which are commonly lighter in color, while dark-colored bands may have minerals like biotite or amphibole, which are darker in color. These variations result from the specific conditions of pressure, temperature, and chemical composition during the rock's formation.
What is a dark colored rock?
Mafic igneous rocks, like basalt, are dark colored and low in silica.
What type of rock makes up the dark spots on the Moon?
The dark spots on the Moon, known as lunar maria, are made up of basalt rock formed from ancient volcanic activity. Basalt is a dark-colored, fine-grained volcanic rock that is rich in iron and magnesium minerals.
How does the density of a light colored rock differ from the density of dark colored rock?
Normally, light colored igneous rocks are less dense compared to dark colored igneous rocks. This is because the light colored rocks have a less iron in them.
How does the density of a light colored igneous rock differ from that of a dark colored igneous rock?
Normally, light colored igneous rocks are less dense compared to dark colored igneous rocks. This is because the light colored rocks have a less iron in them.
Why are some igneous rock dark and other light?
The color of igneous rocks is determined by their mineral composition. Dark-colored igneous rocks, like basalt, contain minerals that are rich in iron and magnesium, which give them their dark appearance. Light-colored igneous rocks, like granite, tend to have higher concentrations of quartz and feldspar minerals, which are lighter in color. Overall, the mineral content and composition of the rock influence its color.

What is an intrusive igneous rock that is dark colored?
gabbro
What is a dark-colored low silica rock?
Mafic igneous rocks, like basalt, are dark colored and low in silica.
