Gabbro is a coarse-grained and usually dark-colored igneous rock.It is an intrusive rock. It means that it formed as magma cooled slowly in the crust. Igneous rocks with similar composition are basalt (extrusive equivalent of gabbro) and diabase (the same rock type could be named dolerite or microgabbro instead).. Gabbro with large augite phenocrysts embedded in white plagioclase.
Gabbro Diabase is a kind of black gabro quarried in Russian Federation. This stone is especially good for Exterior - Interior wall and floor applications, sills, stairs, countertops, mosaic, fountains, pool pavers and other design projects. It also called Gabro Diabase Granite,Gabbro Diabaz,Karelia Black Granite,in Russian:Габбро диабаз .
Diabase ( /ˈdaɪ.əbeɪs/) or dolerite or microgabbro is a mafic, holocrystalline, subvolcanic rock equivalent to volcanic basalt or plutonic gabbro. Diabase dikes and sills are typically shallow intrusive bodies and often exhibit fine grained to aphanitic chilled margins which may contain tachylite (d

Four diamond drill holes were drilled in October 2007 on the Arrow Property in the Pigeon River – Arrow River area of the Thunder Bay mining district. The target of this drilling program was magmatic Ni-Cu sulfide mineralization hosted in gabbroic dikes in the vicinity of the Crystal Lake Gabbro. Drill results are summarized below:
Diabase, also called Dolerite, fine- to medium-grained, dark gray to black intrusive igneous rock.It is extremely hard and tough and is commonly quarried for crushed stone, under the name of trap. Although not popular, it makes an excellent monumental stone and is one of the dark-coloured rocks commercially known as black granite.Diabase is widespread and occurs in dikes (tabular bodies ...
Gabbro (/ ˈɡæbroʊ /) is a phaneritic (coarse-grained), mafic intrusive igneous rock formed from the slow cooling of magnesium-rich and iron-rich magma into a holocrystalline mass deep beneath the Earth 's surface. Slow-cooling, coarse-grained gabbro is chemically equivalent to rapid-cooling, fine .

Diabase / ˈdaɪ. / or dolerite or microgabbro is a mafic, holocrystalline, subvolcanic rock equivalent to volcanic basalt or plutonic gabbro. Diabase dikes and sills are typically shallow intrusive bodies and often exhibit fine grained to aphanitic chilled margins which may contain tachylite (dark mafic glass).
In the United States, an intrusive rock whose main components are labradorite and pyroxene and that is characterized by ophitic texture. As originally applied by Brongniart in 1807, the term corresponded to what is now recognized as diorite.The word has come to mean a pre-Tertiary basalt in Germany, a decomposed basalt in England, and a dike-rock with ophitic texture in the United States and ...
Olivine-gabbro and olivine- norite are characterized by the presence of olivine. The olivine may give the rock a greenish color. Diabase. Diabase is of the same composition as gabbro, but the crystals of feldspar are long (lath-shaped), and they are set in the masses of pyroxene, giving the structure called ophitic. Olivine-diabase is common.
hypersthene-bearing gabbro and is the most common host to PGM sulphide mineralisation in Nipissing Diabase intrusives. Fine-grained to chilled gabbro, proximal to scattered outcroppings of quartzite (Huronian sediments), marks the northern gabbro-sediment contact along the northern part of the grid (Figure 3; see maps PSKOO-01 to 03).
Diabase ( /ˈdaɪ.əbeɪs/) or dolerite or microgabbro is a mafic, holocrystalline, subvolcanic rock equivalent to volcanic basalt or plutonic gabbro. Diabase dikes and sills are typically shallow intrusive bodies and often exhibit fine grained to aphanitic chilled margins which may contain tachylite (dark mafic glass). Diabase is the preferred name in North America, yet dolerite is the ...
Jan 01, 1985· Ores in diabase dikes or sills Most diabase, gabbro and diorite dikes and sills are compositionally uniform and carry an ordinary complement of accessory metallic minerals (Ti-magnetite, ilmenite) which is too low (1-5% by volume) to be of practical importance.
All about Diabase rocks. This is a name given to those varieties of what would otherwise be diorite and gabbro which are too fine-grained in character to enable one to tell whether the dark-colored mineral which they contain is hornblende or pyroxene without the use of a microscope.

Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar. Diabase is available in dark grey to black colors. The streak of a rock is the color of powder produced when it is dragged across an unweathered surface.

Dolerite and Diabase are both mafic igneous rocks having same mineralogical composition, but differ in formation. The colors are frequently dark gray, black and green. Dolerite is medium-grained (Fig. 4.19) intrusive equivalent of volcanic basalt or plutonic gabbro, and usually occurs as dykes (Fig. 4.20), sill and plugs.Dolerite is heavy with specific gravity ranging between 2.9 and 3.3.
diabase is good as buildings materials, the best stone with asphalt concrete as well as the adhesive powder in chemical industry. Thus in the quarrying industry, diabase processing is very popular. In diabase processing line, many mining machines are at demands, such as crushers, mills and so on.
