contact us· Diorite is a plutonic rock that is between granite and gabbro in composition. It consists mostly of white plagioclase feldspar and black hornblende. Unlike granite, diorite has no or very little quartz or alkali feldspar. Unlike gabbro, diorite contains sodic—not calcic—plagioclase.

contact usDiorite. Diorite is a plutonic igneous rock with intermediate composition between mafic and felsic rocks. It is visibly crystalline and usually has a granular texture (composed of roughly equally sized crystals) although the appearance may vary widely. Its volcanic (fine-grained) analogue is andesite. Diorite (red) on the QAPF diagram.
contact us· The permeability of granite with a fine-grained mineral vein agrees well with that of the intact sample, whereas the permeability of granite possessing a macro-fracture filled with clay is lower than that of the macro-fractured sample. The decrease in the permeability is due to the filling of fine-grained minerals and clay in the macro-fracture.

Characteristics of rocks include texture, appearance, color, fracture, streak, hardness etc. Rhyolite vs Diorite characteristics assist us to distinguish and recognize rocks.

Chemical and x-ray analysis of granite and granodiorite can be used to "fingerprint" these rocks, telling their exact composition and where they may have formed. Where is It Located. Granodiorite, like diorite, is the result of fractional melting of a mafic parent rock above a subduction zone.

contact usGranodiorite Granodiorite is an intrusive rock, intermediate in composition between diorite and granite.Although often similar in appearance to diorite or granite, it has a higher quartz content than diorite, and a higher mafic mineral content than granite. It is commonly produced in volcanic arcs, and in mountain building where it emplaces as large batholiths in mountain roots.

Subordinate rock types are granite, fine-grained dioritoid, fine- grained granite, diorite to gabbro, fine-grained diorite to gabbro and pegmatite.
contact usThe minerals that are found in granite are primarily quartz, plagioclase feldspars, potassium or K-feldspars, hornblende and micas. Quartz is usually the last mineral to crystallize and fills in the extra space between the other minerals. Quartz''s hardness, lack of chemical reactivity and near lack of cleavage give granite a significant amount of its desirable durable properties.

contact usConsequently, plutonic rocks tend to have phaneritic texture with interlocking grains and little primary porosity. Plutonic rocks range in composition from felsic to mafic (for example, granite, diorite, and gabbro), which reflects the source of the magma and the timing of mineral crystallization.
contact us· Granite is an intrusive igneous rock, which means it crystallized from molten rock, called magma, miles underground. At these depths, magma is insulated by the rocks around it and cools very slowly, growing large interlocking crystals. Granite is often said to have a "salt-and-pepper" appearance: the lighter-colored minerals are quartz ...

In the solid solution series, the plagioclase refractive index varies from slightly lower than quartz to somewhat above it.
