Basalt Diorite And Granite

If granitic magma or rocks are present there the mixing of basaltic and granitic magmas are taking place under the continental crust plate.

Basalt diorite and granite. This produces a melt that is intermediate in composition between basalt and granite. Diorite results from the partial melting of a mafic rock above a subduction zone. These often form above a convergent plate boundary where an oceanic plate subducts beneath a continental plate. Unlike granite which has pink flecks throughout diorite is characterized by its black white and gray mottled look.

These rocks include andesite basalt dacite obsidian pumice rhyolite scoria and tuff. It is distinguished from gabbro on the basis of the composition of the plagioclase species. This magma cools and crystallizes before reaching the earth s surface resulting in the formation of diorite deposits. Diorite is known for being coarse in texture and is known for its ability to assist with drainage and erosion.

It usually occurs as large intrusions dikes and sills within continental crust. These are usually formed in the arc regions of the upper volcanoes that charm the plates. Diorite forms if this type of melt crystallizes below the surface. Basaltic magma in its composition melts the granite bed diorite produces granitic magma.

Appearance of granite is veined or pebbled and that of diorite is shiny. There the basaltic magma mixes with granitic magmas or melts granitic rock as it ascends through the continental plate. Diorite is the name used for a group of coarse grained igneous rocks with a composition between that of granite and basalt. Examples of intrusive igneous rocks are diabase diorite gabbro granite pegmatite and peridotite.

Diorite is a coarse grained intrusive igneous rock which contains large interlocking and randomly oriented crystals and forms when molten lava does not reach the earth s surface and cools down in the earth s crust. The plagioclase in. Granite is available in black grey orange pink white colors whereas diorite is available in black brown light to dark grey white colors. So when the partial melting of an oceanic plate takes place the resulting basaltic magma rises and intrudes on the rocky continental plate.

Some cool so quickly that they form an amorphous glass. Basalt forms when lava reaches the earth s surface near an active volcano. Diorite is an intrusive igneous rock composed principally of the silicate minerals plagioclase feldspar biotite hornblende and or pyroxene. Hardness of granite and diorite is 6 7.

Information about production of diorite. Diorites may be associated with either granite or gabbro intrusions into which they may subtly merge. Diorite is an intrusive igneous rock. Properties of rock is another aspect for granite vs diorite.

The chemical composition of diorite is intermediate between that of mafic gabbro and felsic granite. Extrusive igneous rocks erupt onto the surface where they cool quickly to form small crystals.
