Microtomographic Study of Gabbro-Diabase Structural
Transformations of the porous space structure for gabbro-diabase under compressive loads is studied. Quantitative assessment of respective structural parameters for the pore space is ensured through the application of X-ray computer microtomography, enabling visualization of the internal three-dimensional structure of each sample and a Le gabbro est un type de roche ignée intrusive à gros grains et de couleur foncée, généralement composée de feldspath plagioclase riche en calcium, de pyroxène et parfois d'olivine. Sa composition est similaire au basalte, qui est son équivalent extrusif.

Diabase an overview ScienceDirect Topics
The Nipissing Diabase is approximately the same age as the Ungava magmatic event (2219+ −1 Ma), and may be related to the Senneterre dyke swarm (2216+ /−8/4 Ma) ( Fig. 2.13 A; Ernst, 2014 ). The rock types are typically gabbroic, but the magmatic event has historically been named based on the less-common development of finer-grained diabase.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)..

It is an intrusive rock, which means it forms from molten magma that cools and solidifies beneath the Earth's surface.

The difference between basalt, diabase, and gabbro is in their grain size which was determined by their cooling rates.

Neoproterozoic concentric intrusive complex of gabbro-diorite
The KGDC represents a large post-collisional layered gabbro-diorite complex covering about 100 km 2. It has an elliptical shape striking NW-SE and tilting to the north with the lower layers (olivine gabbro and gabbronorite) exposed to the south and the upper layers (hornblende gabbro, anorthosite and diorites) exposed to the north.The diabase is typically fine-grained having chilled margin. The main ingredients of dolerite and diabase are mafic lath-shaped plagioclase of about 60% (labradorite, and rarely bytownite) set in a finer matrix of clinopyroxene (typically 20%–30% augite) and ± olivine (up to 10% in olivine diabase), magnetite, and ilmenite (Fig. 5.21).Anorthosite an overview ScienceDirect Topics
