Formation

Formation

Diabase forms when molten igneous rock is squeezed up into a vertical crack in other rocks, the crack is usually forced apart and the molten rock cools in the space to form a tabular igneous intrusion cutting across the surrounding rocks and is known as a dike.
Gabbro, a mafic rock, forms due to cooling and crystallization of magma underneath Earth's surface.

Diabase vs Gabbro Information

Earth’s outer layer is covered by rocks and these rocks have different physical and chemical properties. As two rocks are not same, it’s fun to compare them. You can also know more about Diabase and Gabbro Reserves. Diabase is a fine-grained igneous rock which is composed mostly of pyroxene and feldspar. Gabbro is an intrusive igneous rock which is chemically equivalent to plutonic Basalt. 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 Diabase vs Gabbro information and Diabase vs Gabbro characteristics in the upcoming sections.

Diabase vs Gabbro Characteristics
