“…The determination of sample purity is a prerequisite when using marine chemical sediments such as carbonates as geochemical archives to reconstruct paleo-marine environments and redox conditions of the atmosphere-hydrosphere. The trace element and isotope composition of pristine carbonates can be altered by I) syn-or post-diagenetic fluid flow alteration (e.g., by meteoric/meltwater influx or basin-fluid overprint; Veizer, 1983;Jacobsen and Kaufman, 1999;Hohl et al, 2015a) or II) by leaching of non-carbonate phases within the bulk rock powders during chemical digestions (i.e., detrital aluminosilicates, phosphates and Fe-Mn oxides; e.g., Kamber and Webb, 2001;Viehmann et al, 2020). Both processes, which mask the pristine geochemical composition of carbonates, are discussed in detail below:…”

The study of hydrothermal travertines contributes to the understanding of the interaction between physico‐chemical processes and microbial mats in carbonate precipitation. Three active travertine sites were investigated in Central Italy to characterise the types of carbonate precipitates and the associated microbial mats at varying physico‐chemical parameters. Carbonate precipitated fabrics at the decimetre to millimetre‐scale and microbial mat composition vary with decreasing water temperature: (a) at relatively higher temperature (55–44°C) calcite and aragonite crystals precipitate on microbial mats of Chloroflexi and sulphur‐oxidizing microbes forming filamentous streamer fabrics with sparse cyanobacteria, (b) at intermediate temperature (44–40°C), rafts, coated gas bubbles and dendrites are associated with Spirulina cyanobacteria and other filamentous and rod‐shaped cyanobacteria, (c) low temperature (34–33°C) laminated crusts and oncoids forming in a terraced slope system are associated with diverse Oscillatoriales and Nostocales filamentous cyanobacteria, Spirulina and diatoms. At the microscale, carbonate precipitates are similar in the three sites consisting of prismatic calcite crystals organised in radial rosettes or fibrous aragonite spherulites (40–300 µm in diameter), overlying or embedded in Extracellular Polymeric Substances. Clotted peloidal micrite dominates at temperatures <40°C, also encrusting filamentous microbes. Carbonates are associated with gypsum crystals; extracellular polymeric substances are enriched in silicon, aluminium, magnesium, calcium, phosphorous and sulphur; authigenic aluminium‐silicates form aggregates on Extracellular Polymeric Substances. This study confirms that microbial communities in hydrothermal settings vary as a function of water temperature. Carbonate precipitates at the microscale are similar in the three settings, despite different microbial communities, suggesting that travertine precipitation, driven by carbon dioxide degassing, is influenced by biofilm extracellular polymeric substances acting as a substrate for crystal nucleation (Extracellular Polymeric Substances‐mediated mineralization) and affecting the resultant fabric types, independently from specific microbial community composition and metabolism.

The Middle Ordovician Majiagou marine carbonates in the Ordos Basin, China, are important natural gas exploration targets and potential gas source rocks. However, the hydrocarbon generation potential of marine carbonates is difficult to evaluate due to their old ages, high thermal maturities, and low total organic carbon (TOC) contents. The enrichments of organic matter deposited in the sedimentary period are of significance to the subsequent hydrocarbon generation process. Integrated petrology and geochemistry studies, including mineral and maceral contents, major and trace element contents, TOC, and organic carbon isotope signatures, were carried out on the Majiagou Formation. The detrital input, paleoproductivity, and preservation conditions of organic matter, which are essential control factors for the enrichment of organic matter, were discussed in detail. The results showed that sea level changes regulated the conditions for the enrichment of organic matter in the Majiagou sedimentary period. The third member of the Majiagou Formation (O2m3) resulted in high paleoproductivity (high Ba/Al, Cu/Al, and TOC values), terrigenous input (high Ti/Tiavergae shale and TCP/TOC values), and an anoxic (V/(V + Ni) > 0.6) and salty environment (high anhydrite contents) for the preservation of organic matter. Conversely, there is little organic matter input in the fourth member of the Majiagou Formation (O2m4) under the transgressive environment. Gypsum not only plays a potentially important role in the blooming of special organisms (halophilic archaea) but is also beneficial for the preservation of organic matter.
