Microbes In Basalt Thrive On A Mixed Diet Of Toxic Wastes
BERKELEY, CA — Seventy-five meters beneath the surface of a site in Idaho where radioactive waste has been stored for more than 40 years, microorganisms living in the pores and crevices of dry basaltic rock are able to reduce a toxic form of chromium to a much less toxic form -- and they do so faster in the presence of volatile organic wastes.اقرأ أكثر

15 Types of Ocean Stones - Characteristics ...
Gabbro stone is a dark stone that is similar to Basalt. The formation of Gabbro stone happens when a magma cools down under the Earth's surface. Thus, it also makes up the component of the ocean crust. The Gabbro stone composes most of the crust in mid-ocean ridges. Gabbro stone is made up of nickel, cobalt, silver, gold, platinum, chromium ...اقرأ أكثر
