What are plutonic rocks examples?
Igneous rocks which cool and solidify deep in the earths crust are called plutonic rocks. Examples of plutonic rocks are granite, gabbro, and granodiorite.
What is plutonic rocks?
Definition of plutonic rock : an igneous rock (as granite) of holocrystalline granular texture regarded as having solidified at considerable depth below the surface.
What are some examples of volcanic rocks?
List Volcanic Rocks
- Rhyolite.
- Obsidian.
- Pitchstone.
- Pumice.
- Basalt or Trap.
- Andesite.
What are 2 examples of igneous rocks?
There are two basic types: 1) intrusive igneous rocks such as diorite, gabbro, granite and pegmatite that solidify below the Earth’s surface; and 2) extrusive igneous rocks such as andesite, basalt, obsidian, pumice, rhyolite and scoria that solidify on or above the Earth’s surface.
Is Basalt a plutonic rock?
When magma never reaches the surface and cools to form intrusions (dykes, sills etc) the resulting rocks are called plutonic. The basic classification is the same as for plutonic rocks: with increasing silica content, they include: basalt, andesites, dacites, rhyolite, pumice and obsidian.
Is granite a plutonic rock?
granite, coarse- or medium-grained intrusive igneous rock that is rich in quartz and feldspar; it is the most common plutonic rock of the Earth’s crust, forming by the cooling of magma (silicate melt) at depth.
What are the three types of plutonic rocks?
There are about a dozen major plutonic rock types and many more less common ones. In ascending order, four types include gabbro (dark in color, not much silica), diorite (an intermediate amount of silica), granite (68 percent silica), and pegmatite.
What are the 3 types of sedimentary rocks?
There are three different types of sedimentary rocks: clastic, organic (biological), and chemical. Clastic sedimentary rocks, like sandstone, form from clasts, or pieces of other rock.
What are two examples of felsic rock?
Common felsic minerals include quartz, muscovite, hornblende, orthoclase, and the sodium rich plagioclase feldspars. The most common felsic rock is granite. On the opposite side of the rock spectrum are the iron and magnesium rich mafic and ultramafic minerals and rocks.
What are examples of phaneritic rocks?
Andesite
What are some examples of clastic rocks?
The classic example of clastic rocks is sedimentary rocks. Sedimentary rocks are distinguished by being composed of sediments of varying sizes and composition, and they can be found all over the world.
What are the types of plutons?
The most common rock types in plutons are granite, granodiorite, tonalite, monzonite, and quartz diorite. Generally light colored, coarse-grained plutons of these compositions are referred to as granitoids .
