A remarkably large number of minerals (I've heard estimates as high as 2/3 of all mineral forms) are produced via microbiological activity, e.g. selective oxidation, precipitation, etc. A famous example is the natural uranium reactor Oklo from 2 billion years ago (Congo), formed most likely by microbial precipitation of uranium from seepage water. Today people are investigating the use of microbial uranium precipitation to clean up mine tailings, accident sites, waste leakage etc. from the nuclear sector: https://www.sciencedirect.com/science/article/abs/pii/S03043... |
