“…Some researchers have suggested that seafloor manganese nodules form, at least in part, through such biochemical processes (Lysyuk 2008;Blöthe et al 2015). Microbes have also been invoked in the precipitation of gold (Au; Reith et al 2006Reith et al , 2009Johnston et al 2013;Sanyal and Shuster 2021), copper carbonate (Li and Gadd 2017) (Carpentier et al 2003), and polymorphs of sulfur (Douglas and Yang 2002;Gleeson et al 2011;Cron et al 2019).…”

A systematic survey of 57 different paragenetic modes distributed among 5659 mineral species reveals patterns in the diversity and distribution of minerals related to their evolving formational environments. The earliest minerals in stellar, nebular, asteroid, and primitive Earth contexts were dominated by relatively abundant chemical elements, notably H, C, O, Mg, Al, Si, S, Ca, Ti, Cr, and Fe. Significant mineral diversification subsequently occurred via two main processes, first through gradual selection and concentration of rarer elements by fluid-rock interactions (for example, in hydrothermal metal deposits, complex granite pegmatites, and agpaitic rocks), and then through nearsurface biologically-mediated oxidation and weathering.We find that 3349 mineral species (59.2 %) are known from only one paragenetic context, whereas another 1372 species (24.2 %) are associated with two paragenetic modes. Among the most genetically varied minerals are pyrite, albite, hornblende, corundum, magnetite, calcite, hematite, rutile, and baryte, each with 15 or more known modes of formation. Among the most common paragenetic modes of minerals are near-surface This is the peer-reviewed, final accepted version for American Mineralogist, published by the Mineralogical Society of America.The published version is subject to change.
