Article
Fine-fibrous kerites of the Volyn region represent mummified remains of cyanobacterial mats that functioned in the thermal geyser spring. Alienation of mat from the substrate and its burial in a dry cavity of the self-sealed biogenic-geyser siliceous structure, where mummification of microorganisms occurred owing to the hydrocarbon component under...
Article
The possible environments of carbon hondrites accumulation were discussed. The hydrothermal factors exerted substantial influence on mineral composition of carbon hondrites. It was reported that hydrothermal jells participated in mats organisms lithification.
Article
The source of carbon of Early Archean graphites of Nimnyr suite of Aldan shield was cyanobacterial mat. In the region of its development there existed eucariots of diatoms type. It confirms the earlier supposition that eucariots were as ancient gropu of microorganisms as procariots. A well developed microbiota Early Archean means that there was no...
Article
Ultrathin sectioning and cryofracture of fibrous kerite, sampled from 1.8-1.75 billion year old Volyn sediments (Ukraine), revealed in bacteria-like bodies the presence of structures similar to sheath, cell wall, periplasm, cytoplasm, septum, membranes, intramembrane particles, poly-beta-hydroxybutyrate inclusions. On the strength of these data and...
Article
For the last few years there have been a lot of publications in geological literature on the problem of formation of morphologically unique fine fibrous kerites, found in one of the objects of kamera pegmatites of Volyn (1800 - 1750 mln. years). According to the opinion of all researchers who deal with them, they are an excellent example of a bioge...
Article
The article deals with paleomicrobiological analyses of litified remnants of microbial organisms from carbon hondrites of Murchison, Efremovka and Alliende meteorites as well as general analyses of mineral composition of carbon meteorites. On the basis of this analyses the assumption is made that the cyanobacterial community (mat) from hydrothermal...

Article
Comparative analysis of bacteriomorphic structures in the Murchison and Efremovka meteorites and ancient high-carbon black and oil shales showed that they are analogous to modern microorganisms and their lithified remains in modern halophilic and thermophilic cyanobacterial communities (mats).
Article
Model objects showing biomorphic structures that normally occur in extraterrestrial bodies are discussed. Biomorphic bodies observed in meteorites are described.

The study of the fossilization processes of modern cyanobacteria provides insights needed to recognize bacterial microfossils. The fossilization of cyanobacteria is discussed and images of recent and fossil bacteria and cyanobacteria from the Early Proterozoic to Neogene carbonaceous rocks (kerites, shungites, and black shales) and phosphorites are...

The McKay et all. detection of chemical biomarkers and possible microfossils in an ancient meteorite from Mars (ALH84001) stimulated research in several areas of importance to the newly emerging field of Astrobiology. Their report resulted in a search for additional evidence of microfossils in ancient terrestrial rocks and meteorites. These studies...

High resolution SEM and ESEM investigations carried out independently in Russia and the United States have revealed the presence of numerous posible biogenic microstructures in the Murchison and Efremovka carbonaceous chondrites. Careful in-situ examinations of freshly fractured meteorite surfaces have shown these microstructures to be embedded wit...
Article
Scanning electron microscopy of the mineral matrix of the carbonaceous chondrites Murchison and Efremovka revealed remnants of filiform and coccoid cyanobacteria similar to those that were constituents of the Precambrian and Phanerozoic cyanobacterial mats, which formed high-carbon marine biolithogenetic rocks. It also revealed remnants of microorg...
Article
The Tomtor ore body is a newly discovered unusually rich type of complex scandium-rare-earth-yttrium-niobium ore. There are a wide range of views regarding the origin of this ore body, due to the unusual scale of rare-earth-element concentration and the relatively limited extent of its study. The most recent study carried out on this ore body indic...

... In this case, the accumulation of REE occurred in some kind of shallow lake basin, where cyanobacterial mats gradually increased the REE concentrations from the water draining from the surrounding land. Thirdly, these element-specific microbes often accumulate, for example, Fe, Mn and S [15,16]. Biomarkers of different molecular structures are of relevance for geochemical and geobiological investigations of sedimentary and metamorphic rocks [12,[17][18][19][20][21]. ...
... Genetic, geobiological and fossil evidence indicates that prokaryotic and eukaryotic organisms had colonized Earth during the great bombardment period when hundreds of thousands of meteors, asteroids and comets were slamming into this planet; a time of cosmic turmoil that would have nearly erased almost all evidence of earlier life, but which likely delivered life-bearing debris that was deposited on Earth (Joseph 2000;. Over a dozen meteors--some of which are older than this solar system--have been discovered to contain the fossilized remnants of various organisms including algae and cyanobacteria (Claus & Nagy 1961;Hoover 2011;McKay, et al., 1996McKay, et al., , 1996Pflug 1984;Nagy et al. 1961Nagy et al. , 1963aRozanov & Hoover 2003;Zhmur & Gerasimenko 1999;Zhmur et al. 1997). ...
... Псевдоморфози по мікроорганізмах в метеоритах. В останні роки у зв'язку з освоєнням нової техніки з високими роздільними можливостями зріс інтерес до результатів біологічних досліджень астроматеріалів [9,11,17,43]). Основним джерелом біологічної інформації є метеорити, які відносяться до класу вуглистих хондритів [19]. ...

... While biomorphic structures have been previously found in meteorites (Hoover et al., 1998;Gillet et al., 2000), including meteorites collected from hot deserts (Lee et al., 2012(Lee et al., , 2017Tait et al., 2017b), these studies were mostly concerned with putative ''nanobacteria,'' or modern endolithic eukaryotes contaminating internal surfaces of voids or cracks (Toporski and Steele, 2007). This study will investigate organisms that are entombed within, or that have burrowed within, the secondary mineral phases of meteorites, offering the best chance of preservation for fossils and organics. ...
... The ancient fossils (of different nature inclusive of aged more than 3 bln years), including bacterial, are merely morphologic structures (pseudomorphs). In some cases their nature may be even abiogenous [12]. ...

Since the mid-1990s, different fossilized bacteria and protists were found in the Orgueil meteorite using micropaleontological studies (Gerasimenko et al., 1999;Hoover, 2006aHoover, , 2006bHoover and Rozanov, 2005;Hoover et al., 1998Hoover et al., , 2004Hoover et al., , 2008Hoover et al., , 2018Rozanov, 1996Rozanov, , 2009Zhmur et al., 1997). ...
