What are all the different types of igneous rocks?
The main types of igneous rocks are basalt, granite, andesite, rhyolite, and obsidian. Basalt is fine-grained and forms from rapidly cooling lava, while granite is coarse-grained and forms from slow cooling magma. Andesite and rhyolite fall in between these two in terms of grain size, with obsidian being a volcanic glass with no crystals.
What are the four kinds of igneous rock?
Igneous rocks are usually classified first by their color index. The color index is separated into four categories. Felsic rocks are the lightest and are composed of mostly quartz and potassium feldspar. Intermediate rocks are the second lightest and are made up of mostly plagioclase feldspar, pyroxene, amphibole, and biotite. Mafic rocks are made up of plagioclase feldspar, pyroxene, and amphibole. Ultramafic is made up of mostly olivine, with pyroxene and amphibole.
What is the main mineral type that the oceanic plates are made of?
mostly made of basalt.
Most common volcanic rock?
Basalt is the most common volcanic rock. It is a dark-colored, fine-grained volcanic rock that is found in many volcanic settings around the world. Basalt forms from the rapid cooling of magma on the Earth's surface.
What are the 3 elements are the oceanic crust made of?
The oceanic crust is made out of mostly basalt.
Which igneous minerals are found in gabbro and basalt?
Gabbro and basalt primarily contain the same igneous minerals, with the main difference being their texture and formation. Both typically feature plagioclase feldspar and pyroxene as their dominant minerals. Gabbro, being coarse-grained, often includes additional minerals like olivine and amphibole, while basalt is fine-grained and may contain smaller amounts of these minerals. Overall, both rocks are rich in mafic minerals due to their basaltic composition.
