What is diorite rock?
Diorite is a coarse-grained intrusive igneous rock. It contains large interlocking randomly oriented crystals. It is a dark coloured rock usually medium to dark grey containing many mafic crystals. … Diorite formed deep within the Earth’s crust from cooling magma that never made it to the surface.

Is diorite an intrusive or extrusive rock?
Which minerals form the rocks diorite and andesite?
What metamorphic rock does diorite turn into?
Is diorite volcanic or plutonic?
Diorite is a plutonic igneous rock composed of coarse grains of plagioclase feldspar and less than 40 percent hornblende (see amphibole) and biotite (see mica) or more rarely pyroxene or olivine.
Is dolerite an igneous?
Dolerite is an igneous rock that is rock initially molten and injected as a fluid into older sedimentary rocks. The magma of quartz tholeiite composition was emplaced as a liquid which rose upwards through the basement rocks into older sedimentary rocks of the Parmeener Supergroup.
What type of igneous rock is granite?
Granite. Granite is an igneous rock composed of mostly two minerals: quartz and feldspar. It is an intrusive rock meaning that it crystallized from magma that cooled far below the earth’s surface.

Metamorphic Grade | Low Grade (Low P – Low T) |
Parent Rock | Shale or Mudstone |
What is granite and basalt?
Basalt is an igneous rock or volcanic rock that is produced by the rapid cooling of lava which is rich in magnesium and iron. It is formed at the surface where it will Barden from lava. Granite is a coarse- or medium-grained intrusive igneous rock with a felsic composition.

What is the silica content of diorite?
Compilations of many rock analyses show that rhyolite and granite are felsic with an average silica content of about 72 percent syenite diorite and monzonite are intermediate with an average silica content of 59 percent gabbro and basalt are mafic with an average silica content of 48 percent and peridotite is …
What type of igneous rock is andesite?
What type of rock is andesite?
Andesite most commonly denotes fine-grained usually porphyritic rocks in composition these correspond roughly to the intrusive igneous rock diorite and consist essentially of andesine (a plagioclase feldspar) and one or more ferromagnesian minerals such as pyroxene or biotite.

What is a plutonic rock?
intrusive rock also called plutonic rock igneous rock formed from magma forced into older rocks at depths within the Earth’s crust which then slowly solidifies below the Earth’s surface though it may later be exposed by erosion. Igneous intrusions form a variety of rock types. See also extrusive rock.
What type of stone is dolerite?
Dolerite is the name given to the medium-grained intrusive basic igneous rock commonly found in dykes and sills in North America and continental Europe it is often referred to as diabase but many authors restrict this term to altered dolerite.
