AB - The role of biogenicity in the mineral world is larger than many might assume. Biological processes and physical and chemical processes interact both at the Earth’s surface and far underground, leading to the formation of banded iron and manganese deposits, among others. Microbial mats can form giant sedimentary ore deposits, which include enrichment of further elements. This article reviews the ways in which microbially-mediated processes contribute to mineralization, the importance of mineralized microbial textural features, and the methods that must be used to obtain high-resolution datasets. If the chosen methodology and/or the size dimension of investigation is not appropriate, then it is not possible to recognize that a system is microbially mediated, and the conclusion will be incomplete. We call attention to variable authigenic mineralization as the result of complex mineralization of cells and extracellular polymeric substances in the starving basins, which form giant ore deposits together with ore-forming minerals. Microbial mats and other biosignatures can serve as indicators of environmental reconstruction in ore formations. We suggest tests and analyses that will allow the potential role of biomineralization to be properly investigated for a more comprehensive view of formation processes and their implications.

These include not only observations of Opportunity, Spirit and Curiosity, but also interpretations of Martian surface geological changes observed by imaging Martian orbiters, and probable life traces found in meteorites, too. When we put Martian terraformation into perspective today, we must already take into account all the biosignatures of the ancient Martian life. There are several organizational levels of biology where signatures of early life on Earth has been observed. In this paper our first approach is to collect and interprete the biosignatures arranged according to the system governed by structural hierarchy of organizational levels of living beings. Although it is difficult to realize the joint existence of several observations at different levels of hierarchy (isotopes, molecules, minerals, microscopic texture) only those data systems give strong evidence of early life, which result from mutually embedded hierarchical structures together. Over terrestrial data, Martian space probe’s datasets about the Martian rocks and surface, the analyses of weathering and mineral transformations of Martian and chondritic meteorites are tools and promisful observational possibilities of early Martian terraformation. On the first place the terrestrial rocks were studied where texture-transformation characteristics of microbial constituents, especially iron bacteria are existing biosignatures on several organizational levels. We found Martian and chondritic meteoritic microtextural counterparts to these terrestrial parallels, illustrating what life forms may have been present in Mars’ past. We have taken this detour from the Martian meteorites to the parallel microbial features of the chondritic meteorites because we believe, that the Martian terraformation may have started very early even on the incoming solar system collisional (meteoritical) debris, originating from earlier (previous to Sun) stellar planetary systems. © 2022 Scrivener Publishing LLC.

High-resolution optical- and cathodoluminescence microscopy, as well as Raman and FTIR spectroscopy show that the lower Mn-1 is ferruginous, while the upper Mn-1 consists mainly of 30-75 vol% braunite, < 0.5% aegirine, 3-15% quartz, 5-10% feldspar, and 1-5% clay minerals, including apatite, chlorite, and organic matter. Here, we model the control of this ore mineralogy by homogeneous oxidation and microbial processes. Layers Mn-2 and Mn-3 contain kremydilite, as a characteristic ore structure, with 77-95 vol% cryptomelane, 0-23% hollandite, 9-19% braunite, 7-21% hematite, and 0-5% pores filled with clay minerals and organic matter. These are present within a micro-nodule matrix composed of cryptomelane and hematite in varying proportions. The first syngenetic products of microbial enzymatic oxidation were, on the Fe side, ferrihydrite and lepidocrocite, and on the Mn side, vernadite, todorokite, birnessite, and manganite. These formed under obligatory oxic (Mn) and suboxic (Fe) conditions and close to neutral pH. We describe the genesis of Urucum via complex diagenetic processes, which include the decomposition and mineralization of cellular- and extracellular-polymeric substances from Fe and Mn bacteria and cyanobacteria. The kremydilite forms in successive stages of oxidation of organic matter mediated by microbes, which generate pores and produce methane and CO2/H-2 bubbles. They are a unique type of diagenetic structure formed by heterotrophic cell colonies randomly activated in the microbialite milieu following burial in suboxic neutral/alkaline conditions, side-by-side with the lithification and stabilization of the mineral assemblages.Significance statement The Neoproterozoic Urucum manganese deposit (Brazil) is a similar to 600 Mt microbially-mediated sedimentary Mn ore. Proto-ore formation via sedimentation and diagenesis occurred under suboxicoxic-oxic and semi-neutral pH conditions in the Ediacaran ocean, wherein microbial Mn(II) oxidation ensued from the fine-grained accumulation of Mn oxides and organic matter. Oxic conditions that facilitated enzymatic Mn oxidation and overwhelmed microbial Fe oxidation appears as a sharp contact between manganese and iron beds. The Urucum deposit arose from a complex suite of diagenetic processes, including decomposition and mineralization of microbially-derived organic matter involving extracellular polymeric substances. Kremydilite - a new type of diagenetic concentric Mn mineral structure formed by randomly activated heterotrophic cell colonies that generated pores in the microbialite sediment after burial, coincident with lithification.
