Distribution and Formation: Basalt is the most common rock type found in oceanic crust, where it forms the ocean floor and mid-ocean ridges. It is also found in continental crust, where it forms the majority of the Earth's continental crust.
Columnar basalt is a type of igneous rock formed from the cooling and solidification of lava flows. As the lava cools, it contracts and cracks, often forming closely packed polygonal columns, typically hexagonal. These columns can be massive, reaching heights of tens of meters.
Basalt, a marvelous rock formed from volcanic activity, holds a significant place in the geologic landscape and human history. Its fascinating properties, wide-ranging applications, and profound natural beauty make it a subject worth exploring.
Basalt is a dark-colored, fine-grained, igneous rock composed mainly of plagioclase and pyroxene minerals. It most commonly forms as an extrusive rock, such as a lava flow, but can also form in small intrusive bodies, such as an igneous dike or a thin sill. It …
Basalt is defined as a fine-grained, dark-colored igneous rock composed mainly of plagioclase and pyroxene minerals, with or without olivine. It is formed from the rapid cooling of basaltic lava exposed at or very near the surface of the Earth (extrusive or volcanic rock).
Basalt is a dark-colored, fine-grained, igneous rock composed mainly of plagioclase and pyroxene minerals. It most commonly forms as an extrusive rock, such as a lava flow, but can also form in small intrusive bodies, such as an …
Basalt, extrusive igneous (volcanic) rock that is low in silica content, dark in color, and comparatively rich in iron and magnesium. Basalts may be broadly classified on a chemical and petrographic basis into two main groups: the tholeiitic and the alkali basalts. Learn more about basalt in this article.

Basalt is a hard, fine-grained, dark-colored volcanic or extrusive rock. It has primarily calcium-rich plagioclase and augite. Also, it may have minor amounts of other minerals like quartz, olivine, foids, alkali feldspar, biotite, and amphibole. This rock is undoubtedly popular, only rivaled by granite.
A basalt column is a pillar of rock formed from hardened lava in the aftermath of a volcanic eruption. A basalt column takes thousands of years, sometimes millions, to form. This article describes the process of lava turning to basalt columns.

Basalt is a type of volcanic rock that is formed from the solidification of molten lava. It is an igneous rock, meaning it is formed through the cooling and solidification of magma or lava. Basalt is one of the most common rock types on Earth, and it can be found in various locations around the world, both on land and under the ocean floor.
Basalt is a common volcanic rock formed from the rapid cooling of basaltic lava exposed at or very near the surface of our planet. Jointed basalt columns, as the most famous and most beautiful basalt formations, exists on many places on earth.
Columnar basalt is a type of igneous rock formed from the cooling and solidification of lava flows. As the lava cools, it contracts and cracks, often forming closely packed polygonal columns, typically hexagonal. These columns can …
Basalt is a widespread rock type that occurs in many parts of the world. It is associated with volcanic activity and can be found in various geologic settings, both on land and under the ocean floor. Here are some of the major occurrences and distributions of basalt globally: 1. Oceanic …
