Olivine basalt from Oahu -

Olivine is denser than most other minerals in basalt and it is also one of the first to start crystallizing. Hence, it often sinks, if it has room to do so, and forms basalts that are abnormally enriched in olivine in the lower part of lava flows for example.

About Basalt Fiber – Basalt America

Basalt Rebar is a derivative from the most abundant rock on earth: basalt. Thousands of fibers are compressed, and wound spirally into a structural reinforcement rod. Deep within the planet, massive plates have been churning for billions of years, creating minerals which we commonly call rocks.

Basalt - Wikipedia

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.
