Basalt Diorite And Granite

There the basaltic magma mixes with granitic magmas or melts granitic rock as it ascends through the continental plate.

Basalt diorite and granite.

Diorites may be associated with either granite or gabbro intrusions into which they may subtly merge. These rocks include andesite basalt dacite obsidian pumice rhyolite scoria and tuff. This produces a melt that is intermediate in composition between basalt and granite. Examples of intrusive igneous rocks are diabase diorite gabbro granite pegmatite and peridotite.

It usually occurs as large intrusions dikes and sills within continental crust. The chemical composition of diorite is intermediate between that of mafic gabbro and felsic granite. These often form above a convergent plate boundary where an oceanic plate subducts beneath a continental plate. Diorite forms if this type of melt crystallizes below the surface.

Diorite is an intrusive igneous rock composed principally of the silicate minerals plagioclase feldspar biotite hornblende and or pyroxene. Diorite is the name used for a group of coarse grained igneous rocks with a composition between that of granite and basalt. This magma cools and crystallizes before reaching the earth s surface resulting in the formation of diorite deposits. Unlike granite which has pink flecks throughout diorite is characterized by its black white and gray mottled look.

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. Information about production of diorite. Diorite is also a type of igneous rock and is similar in composition to granite and basalt although not identical.

Diorite is an intrusive igneous rock. Granite is available in black grey orange pink white colors whereas diorite is available in black brown light to dark grey white colors. Properties of rock is another aspect for granite vs diorite. Basalt forms when lava reaches the earth s surface near an active volcano.

Diorite is known for being coarse in texture and is known for its ability to assist with drainage and erosion. Extrusive igneous rocks erupt onto the surface where they cool quickly to form small crystals. Appearance of granite is veined or pebbled and that of diorite is shiny. The plagioclase in.

Basaltic magma in its composition melts the granite bed diorite produces granitic magma. If granitic magma or rocks are present there the mixing of basaltic and granitic magmas are taking place under the continental crust plate. These are usually formed in the arc regions of the upper volcanoes that charm the plates. It is distinguished from gabbro on the basis of the composition of the plagioclase species.

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. Hardness of granite and diorite is 6 7.
