Basalt - Minnesota Geological Survey
Shown here is an example of amygdaloidal basalt. The grey-brown basalt is riddled with vesicles, or holes, created when gas was trapped within the lava flow as it cooled. The cavities have since been filled by minerals to form zeolites or agates (light colored nodules in the above picture).

Basalt: Pillow basalt is also produced by some subglacial volcanic eruptions. Basalt: Ancient Precambrian basalts are usually only found in fold and thrust belts, and are often heavily metamorphosed. These are known as greenstone belts, because low-grade metamorphism of basalt produces chlorite, actinolite, epidote and other green minerals. Basalt

basalt | Definition, Properties, & Facts | Britannica
Minerals of the feldspathoid group occur in a large number of basaltic rocks belonging to the alkali group; nepheline, analcime, and leucite are the commonest, but haüynite is occasionally present. If nepheline entirely replaces feldspar, the rock is known as nepheline-basalt; if the replacement is only partial, the term nepheline-basanite is used. . Similarly, there are analcime- and leucite ...

Chromite crystals in olivine in a primitive basalt. Chromite is dark-brown to opaque at full thin section thickness. Chromite is a spinel-type mineral, like magnetite, and has an extensive solid solution in the magnetite composition direction. Cr-Mg-Al-rich chromites are realtively transparent, and can be dark-brown at full thin section thickness.

The upper part of the mantle consists of the rock peridotite, which is even more mafic than basalt, so much more so that it's called ultramafic.Where the Earth's plates are pulled apart, at the mid-ocean ridges, the release of pressure on the peridotite makes it start to melt—the exact composition of the melt depends on many details, but in general it cools and separates into the minerals ...

Basalte — Wikipédia
Le basalte est une roche magmatique volcanique issue d'un magma refroidi rapidement et caractérisée par sa composition minéralogique : plagioclases (50 %), de pyroxènes (25 à 40 %), d'olivine (10 à 25 %), et de 2 à 3 % de magnétite.Sur Terre, il a une origine volcanique et est un des constituants principaux de la croûte océanique.Sur la Lune, elle constitue la surface des mers lunaires.
