When the grains have deposited into a sedimentary bed, over time, they will just be grains of minerals. If there are other forms of igneous rock nearby and they erode into the same bed, over the same period, noone will be able to distinguish a gabbro portion from another host rock portion.
From the ancient language to modern Italian, the name migrated to the "gabbro" transcription. Often the name is used as gabbro diabase, which indicates the origin of the stone as a crystallinegranular igneous rock. The age of the breed is about 4 billion years, the beginning of their formation belongs to the most ancient the Archean period.
On Attu Island, diabase and gabbro that intrude map unit Tba have yielded K/Ar wholerock ages of ± and ± Ma (DeLong and McDowell, 1975). On Amlia Island, gabbro has yielded a K/Ar age of ± Ma (McLean and others, 1983). Drewes and others (1961) mapped a gabbro body they inferred was a border facies of the granitic Shaler ...
Gabbrodiabase is one of the varieties of natural stone. The characteristic black coloration with small colored patches distinguishes this mineral from other species. The special density of gabbrodiabase creates great difficulties in attempts to split a stone block. The processing of the material is a very laborious process, requiring the use ...
The gabbro sites are located approximately in the middle of the north ern segment, whereas the peridotite site is located near the offset of the northern and southern spreading segments at 23°21'N. Diabase dikes were encountered crosscutting the peridotite in Holes 920B and 920D and crosscutting the gabbro section in Holes 92IB and 92IC.

Diabase or Dolerite. Diabase or dolerite 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 differ from gabbros chiefly in ...
The Turinge gabbrodiabase is located in the boundary between the Transscandinavian Igneous Belt (TIB) and the Central Svecofennian province ( Fig. 1 ). The Ma TIB generally follows the western and southwestern margins of the Ma crust formed during the Svecofennian orogenic belts ( Fig. 1) ( Högdahl et al., 2004 ).

Gabbrodiabase (the outdated name gabbrodolerite) is a fullcrystalline finegrained volcanic rock, chemically and in mineral composition close to basalt. Diabase is characterized by a relatively low content of silica (4552%). Dolerite is dark gray or greenish black in color. The structure is diabase (ophitic); formed by randomly arranged ...

Diabase is actually a variety of gabbro which consists mainly of labradorite feldspar, augite, magnetite, and olivine. The grain size of diabase is on the smaller side. Diabase and gabbro have the same general mineral composition as basalt, but they have a larger grain size. Basalt is identical to diabase and gabbro, but is very finegrained.
What makes a rock "basic" is not its Ph, but its level of silica content 4555% silica makes a rock basic. Basalt, gabbro, diabase, and phonolite are all igneous rocks, produced in volcanic conditions. Basalt and phonolite are formed in actual eruptions, while gabbro and diabase with their larger grain sizes are formed by cooling more ...

A diabase is a kind of basic intrusive igneous rock with low silica content and high iron content. It belongs to the coarsegrained or finegrained gabbro family. The diabase is dark gray or black, with a natural luster. The main ores are magnetite, ilmenite, chromite, and sulfides such as pyrrhotite and chalcopyrite.

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). Diabase normally has a fine, but visible texture of euhedral lathshaped plagioclase ...
Gabbro is also called norite Plutonic equivalent to basalt Diabase (or dolerite) is a fine grained gabbro containing granular pyroxene and randomly oriented laths of plagioclase, formed by faster cooling in dikes and sills. A variety of Diabase is the slightly metamorphic basalt in the Alps. Classification Class Broader Terms Narrower Terms

Gabbro igneous rock, which also known as "Diabase", but it has small difference because of a bit different relations between mineral elements. The color is black, but sometimes it can have a bit darkgreen color, which depends on deposit. Because of its mineral properties and mechanical characteristics, gabbro is almost the same as black granite. ...
