Basalt is rich in iron and magnesium and is mainly composed of olivine, pyroxene, and plagioclase. Most specimens are compact, fine-grained, and glassy. They can also be porphyritic, with phenocrysts of olivine, augite, or plagioclase. Holes left by gas bubbles can give basalt a coarsely porous texture. Group – volcanic. So, a rock that looks like Swiss cheese has a vesicular texture. Vesicles range in shape from spherical to elongated and in size from ~1mm to more than 1 cm. Basalts are most commonly vesicular. The drop in pressure that a magma experiences as it flows from underground to the Earth's surface allows water and gases in the lava to form bubbles.Description.

Vesicular texture -- basalt scoria: This is an extrusive igneous rock that chilled very quickly, so that the bubbles (vesicles) formed by escaping gas were preserved. Glassy texture -- obsidian: This is an extrusive igneous rock in which a viscous high-silica magma cooled so rapidly that no crystals had a chance to formOlivine Basalt Porphyry. Porphyry is a term that refers to the texture of a rock, rather than its chemical or mineralogical composition. Indeed, porphyries are generally defined as igneous rocks that feature large, prominent crystals embedded in a finer groundmass matrix. Porphyries are formed through two different phases of solidification.This coarse grained texture can be labeled porphyric or a mixture of large and finer grained crystals, which are very large crystals. The time required for the liquid rock to cool will determine the texture. On the other hand, the basalt is an extrusive magmatic rock. The surface is much closer to the surface of the earth and therefore the ...Abstract. Komatiites and variolitic basalts are widespread in Archean volcanic sequences.

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.In thin section the rock is a coarse grained basalt, with a framework of plagioclase laths 1-3 mm long that have been extensively altered to clays. Pyroxene is much less altered and exhibits a poikillitic texture (a large grain containing smaller grains of another species).Average chemical composition of basalt determined by 3594 chemical analyses of basaltic rocks.
