Basalt Rock - Formation, Fun Fact, Properties, Uses ...

Basalt rock is mainly composed of pyroxene, olivine, and plagioclase and is the most common rock on the earth's surface. The texture of basalt rocks is coarsely porous as those holes are left by gas bubbles. The specimens of these rocks are mostly fine-grained, glassy and compact. A large part of the ocean floors is made from basalt rocks.

What Colour is basalt rock? - findanyanswer

2020-6-16 · What Colour is basalt rock? 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.
