“…This was also recognised by Jones and Renaut (2010), who state that the tufa classification of Ford and Pedley (1996) accounts for tufa deposition predominantly in a cool, temperate climate and does not sufficiently consider other (e.g. tropical) climates (Carthew et al, 2003;Shiraishi et al, 2022). A global view of rock coast microbialite classification relies upon detailed description, study and comparison of sites around the globe.…”

Abstract. Microbialites are known from a range of terrestrial, freshwater, marine, and marginal settings with the applied descriptive terminology depending largely on the historical legacy derived from previous studies in similar environmental settings. This has led to a diversity of nomenclature and a lack of conformity in the terms used to describe and categorise microbialites. As the role of microbial mats and biofilms is increasingly recognised in the formation of tufa and terrestrial carbonates, deposits such as tufa microbialites bridge the spectrum of microbialites and terrestrial carbonate deposits. Groundwater spring-fed tufa microbialites in supratidal rock coast environments occur at the interface of terrestrial and marine domains and necessitatethe adoption of an integrative and systematic nomenclature approach. To date, their global distribution and complex relationships with pre-defined deposits have resulted in the application of a variety of descriptive terminologies, most frequently at the macro- and meso-scale. Here we review and consolidate the multi-scale library of terminologies for microbialites and present a new geomorphological scheme for their description and classification. This scheme has greater alignment with terrestrial carbonate nomenclature at the macroscale and with marine and lacustrine microbialites at the mesoscale. The proposed terminology can primarily be applied to tufa microbialites in spring-fed supratidal settings but may also be applied to other relevant environmental settings, terrestrial carbonates, microbial mats and other microbialites.

“…In extant cyanobacteria, carbonate precipitation is associated with the extracellular polymeric substances (EPS) and the sheath (Pentecost and Franke 2010;Shiraishi et al 2020Shiraishi et al , 2022a and is probably boosted by heterotrophic bacteria and their metabolic activity. Abiotic CaCO 3 precipitation is also of importance (Knorre and Krumbein 2000, Shiraishi et al 2022b).…”

“…This organo-matrix does not necessarily reflect living organisms but can represent decaying or lysed organic tissues and organic matter (Dupraz et al 2009). Organomineralization can be extrinsically caused by environmental changes, e.g., degassing of CO 2 , evaporation of H 2 O (Shiraishi et al 2022b) or intrinsically caused by Page 9 of 21 microbial metabolisms (Dupraz et al 2009;Shiraishi et al 2020Shiraishi et al , 2022a.…”

“…13a). In modern cyanobacteria, nucleation of CaCO 3 starts on or within the mucilaginous sheath (Pentecost and Riding 1986;Riding 1991;Shiraishi et al 2020Shiraishi et al , 2022a. In extant Rivularia periodica, calcification nucleates at the outer surface of the sheaths, too (Obenlüneschloss 1991).…”

“…Metabolically active cyanobacteria and heterotrophic bacteria, degradation of EPS leads to the release of Ca 2+ cations into the microenvironment (Paerl et al 2001;Dupraz et al 2009;Shiraishi et al 2020Shiraishi et al , 2022a. The oxidation of acidic groups results in the formation of CO 3 2ions (Dupraz et al 2009;Shiraishi et al 2020Shiraishi et al , 2022a. The subsequent binding of Ca 2+ cations to the CO 3 2− ions leads to the nucleation of CaCO 3 on the organo-matrix (Fig.…”

During the Middle Miocene, an extensive lake district existed along the southern margin of today’s Swabian Alb (Baden–Württemberg). Sediments include a wide range from marls to pure carbonates of lacustrine and palustrine origin that contain microbialites studied here. These sediments are part of the Obere Süßwassermolasse known as Silvana Beds. Macroscopically the studied microbialites show a distinctive layering with an alternation of whitish and tan-colored layers. Petrographic thin sections as well as SEM studies reveal a microstructure of the microbialites comprising an unbranched filament zone formed by erect and parallel calcified filaments as well as a zone of branching filaments forming shrubs of the Dichothrix morphotype. We define two patterns of mineralization for the studied microbialites: (1) shape-retentive mineralization: successive carbonate precipitation along the filament surface. (2) shape-obscuring mineralization: clusters of clotted micritic precipitates along and within the vicinity of micro-sparitic tubules that probably represent remains of the former cyanobacterial sheaths.
