Some of the most primitive organisms close to the base of the phylogenetic tree are thermophilic microbes.
The assumption that volcanic rocks served as habitats for the early microbial life was not unexpected. Consequently, it is possible to say, that volcanogenic rocks are not the obstacle for finding traces of life in them. So, well preserved pillow-lavas, that are the main component of Arkhaean and Early Paleoproterozoic greenstone belts, could be the most perspective for searching of traces of ancient life on the Earth. Our studies confirmed that basaltic glass of the Early Precambrian submarine eruptions was inhabited by microbes in a similar way as it had been done for volcanic glass of modern eruptions. * Paleontological Institute of Russian Academy of Sciences, 117997 Profsoyusnaya 123, Moscow, Russia ** Institute of Geology of Ore deposits, Petrography, Mineralogy, and Geochemistry of Russian Academy of Sciences, 119017 Staromonetny 35, Moscow, Russia Microbial complexes from volcanogenic rocks both ancient ( Early Paleoproterozoic (2.41 GA) basalt pillow-lavas with inclusions of volcanic glass from Karelia) and recent (fresh volcanic glass from pillow-lavas of underwater Middle-Atlantic Ridge were revealed, studied and compared.
