	abstract = {Continental rifting of the Tisza microplate started during the Late Jurassic and resulted in phreatic eruptions, peperite, and the construction of a volcanic edifice in the Early Cretaceous in the Mecsek Mountains (South Hungary). In the SE direction from the volcanic edifice at Zengővárkony, a shallow marine (depth 100–200 m) carbonate sediment hosted a vent environment, and iron ore deposition occurred at the end of the Valanginian to early Hauterivian, hosting a diverse, endemic fauna of approximately 60 species. The detailed mineralogical analysis of the transport conduits included Fe oxides (ferrihydrite, goethite, hematite, and magnetite), quartz, mixed carbonate, pyrite, feldspar, Fe-bearing clay minerals, apatite, sulfates (barite, gypsum, and jarosite), and native sulfur. Filamentous, microbially mediated microtextures with inner sequented, necklace-like spheric forms (diameter of 1 μm) and bacterial laminae are also observed inside decapod crustacean coprolites (Palaxius tetraochetarius) and in the rock matrix. This complex ecological and mineralogical analysis provided direct evidence for the presence of bacteria in fossil sediment-hosted vent (SHV) environments on the one hand and for the intimate connection between bacteria and decapod crustaceans in hydrothermal environments 135 Ma before. This observation completes the fossil food chain of chemosynthesis-based ecosystems, from primary producers to the top carnivores reported for the first time from this locality.},

	abstract = {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.},

	abstract = {By using space probe data we could find traces of the presence of Martian life from several sides. 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.},
