Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar. These rocks are composed of many distinct minerals. The process of formation of rocks is different for various rocks. Rocks are quarried from many years for various purposes. You can check out Gabbro vs Diabase information and Gabbro vs Diabase ...

Examples of intrusive igneous rocks are: diabase, diorite, gabbro, granite, pegmatite, and peridotite. Extrusive igneous rocks erupt onto the surface, where they cool quickly to form small crystals. Some cool so quickly that they form an amorphous glass. These rocks include: andesite, basalt, dacite, obsidian, pumice, rhyolite, scoria, and tuff ...

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 fine-grained. Basalt is from a melt that cooled very rapidly- in other words, on the surface of the earth or in the ocean.

A stone of igneous origin, characterized by a rich granular structure and subtle shades. The geological age of the rock is more than 2.5 billion years, while the closest analogues of gabbro-diabase are less than 1.5 billion years old.

In the United States and Canada, the name " diabase " is used for a dark gray to black, fine-grained, intrusive igneous rock that has a composition similar to basalt and gabbro. The difference between basalt, diabase, and gabbro is in their grain size - which was determined by their cooling rates. Basalt: rapid cooling in a lava flow produced ...

The lithologic association of peridotite, gabbro, diabase, and plagiogranite is characteristic of ophiolites. Whole-rock compositions of NMC plagiogranite, gabbro, and diabase document that these have a suprasubduction zone tectonic affinity, similar to the CAO (Floyd et al., 2000; Yalınız et al., 2008) (Figs. 11A, 11B, 13A, and 13B).

Sills are 365 to 400 m (1,197-1,312 ft) thick. Dikes range in thickness from 3 to 10 m (10-33 ft) and are many kilometers long. Diabase dikes (Late Proterozoic) (Ratcliffe, 1987; Puffer and others, 1991) - Medium- to dark greenish-gray, aphanitic to fine-grained dikes that are dense and hard.

Conclusion. Overall, diabase and gabbro are very similar in composition and appearance, but there are some key differences. Diabase is generally found as dikes and sills, while gabbro is usually an intrusion into the Earth's crust. Additionally, diabase has higher specific gravity and harder mineral content than gabbro.

Sheeted diabase having the thickness of around 100 m generally covers the saussurite gabbro. A contact relation between the sheeted diabase and gabbro is illustrated in Figure 2. Chilled mar-ginal facies found within the sheeted diabase mass suggests that the diabase mass was formed by multiple intrusions.
