Basalt is known for its dark color, typically ranging from black to dark gray, and its fine-grained texture. It is composed mostly of minerals such as pyroxene, plagioclase feldspar, and sometimes olivine. Basalt can have a range of compositions, but it is typically rich in iron and magnesium, and low in silica. Vesicular and Amygdaloidal Textures 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 has a composition similar to gabbro.

Figure 4.1.1 4.1. 1: Granite is a classic coarse-grained (phaneritic) intrusive igneous rock. The different colors are unique minerals. The black colors are likely two or three different minerals. If magma cools slowly, deep within the crust, the resulting rock is called intrusive or plutonic. A seamless stone texture with a basalt surface. The image represents a physical area of 2200 x 1730 mm (86.6 x 68.1 inches) in total. Basalt is a distinctive, dark natural stone used commonly within architecture and construction. While historically used as a crushed aggregate material in roads, concrete, and railways, basalt has also become. Basalt is an extrusive igneous rock composed primarily of plagioclase feldspar and large amounts of mafic minerals like pyroxene. It has an aphanitic texture, meaning its interlocking crystals cannot be seen by the naked eye. It is usually dark gray, black, or dark greenish, and is often vesicular or porphyritic. Basalt is mainly made of two minerals: Plagioclase feldspar and pyroxene . Basalt has several textural varieties such as glassy, massive, porphyritic, vesicular, scoriaceous.
Black Basalt 3/8″ ANS Materials
Basalt's texture is fine-grained due to its rapid cooling at or near the Earth's surface, resulting in an aphanitic texture where individual mineral grains are not visible to the naked eye. Basalt Basalt ( UK: / ˈbæsɔːlt, - əlt /; [1] US: / bəˈsɔːlt, ˈbeɪsɔːlt /) [2] is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low- viscosity lava rich in magnesium and iron ( mafic lava) exposed at or very near the surface of a rocky planet or moon. More than 90% of all volcanic rock on Earth is basalt.

Vesicular volcanic rocks: Vesicular is the adjective used to modify the name of any fine-grained igneous (volcanic) rock which has vesicles (holes from gas bubbles), making a cinder-like or clinker-like appearance. Example: Vesicular basalt. Scoria: Basalt with over 50% vesicles. It looks like cinders.
Black Basalt Honed Distributor
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. Yes, Italys Pietra Lavica Basalt can be used in landscaping. Pietra Lavica Basalt is a volcanic stone that is known for its durability and natural beauty. Its dark color and unique texture make it a popular choice for various landscaping applications such as paving, wall cladding, decorative features, and outdoor furniture.

Basalt is usually grey to black in colour, but rapidly weathers to brown or rust-red due to oxidation of its mafic (iron-rich) minerals into hematite and other iron oxides and hydroxides. Although usually characterized as "dark", basaltic rocks exhibit a wide range of shading due to regional geochemical processes.
