What are the associated rocks and their textures?
Magmatic fluids coming from the intrusive rock may also take part in the metamorphic reactions.
What are 2 textures of metamorphic rock?
The two textures of metamorphic rocks are the Foliate and Non-foliate textures.
What kind of texture can a chemically formed rock have?
All sorts as all rocks have their own textures and are all formed from chemical compounds, but the primarily chemically-formed ones are the igneous rocks and associated minerals.
What is the difference between contact metamorphosis and regional metamorphosis?
Contact metamorphosis occurs when pre-existing rocks are altered primarily due to the heat from nearby molten magma or lava, resulting in localized changes. In contrast, regional metamorphosis affects larger areas of rocks due to high pressures and temperatures, often associated with tectonic processes such as mountain building. While contact metamorphism typically produces more localized and specific mineral changes, regional metamorphism leads to widespread alterations and the formation of foliated textures in rocks.
Do metamorphic rocks have different kinds of textures?
True it does.
What results when rocks come in contact with molten rocks such as those in an igneous intrustion?
When rocks come in contact with molten rocks from an igneous intrusion, the surrounding rocks may undergo contact metamorphism, where their mineralogy and texture are altered due to the heat and chemical reactions with the intruding magma. This can result in the formation of new minerals and textures in the rocks near the intrusion boundary.
Do detrital sedimentary rocks have clastic textures?
Yes, detrital sedimentary rocks have clastic textures. Clastic textures are composed of fragments or grains derived from pre-existing rocks or minerals, which are then compacted and cemented together to form the new rock. Detrital sedimentary rocks, such as sandstone and shale, are formed through the deposition and lithification of these clastic particles.
What are the 4 textures and 4 compositions about igneous rocks?
in geology
Rocks subjected to intense heat when they are intruded by magma undergo a process called?
metamorphism, where the rocks are altered in mineral composition and texture due to high temperature and pressure. This process can result in the formation of new minerals and textures, ultimately leading to the creation of metamorphic rocks.
Which two igneous rocks have phaneritic textures?
Even in the most generalized classification, more than two igneous rocks have phaneritic textures. In that generalized classification, they are granite, diorite, gabbro, and peridotite.
What are some common textures in igneous rocks?
hard rough and not smooth
What best describes intrusive rocks?
Intrusive rocks are igneous rocks that form beneath the Earth's surface from the cooling and solidification of magma. They often have coarse-grained textures due to slower cooling, and examples include diorite, granite, and gabbro. Intrusive rocks are typically associated with plutonic formations and can be exposed at the Earth's surface through uplifting and erosion.
