    Published 2022-05-01
    “…These processes may have influenced not only the geochemical environment of, e.g., early Mars and other planets, but also the peculiar prebiotic chemistry on early Earth. Here, we present a synergistic experimental and computational investigation of the intermediates of chemical reactions of the formamide-based synthesis of canonical and non-canonical nucleobases by thermochemistry in hot hydrothermal crater environments. …”

    HEAT FLOW DENSITY DISTRIBUTION MAP OF THE FOUNDATION ROOF IN THE EASTERN PART OF THE TOMSK REGION by Valery I. Isaev, Galina Lobova, Anna S. Merenkova, Elizaveta N. Osipova, Stanislav G. Kuzmenkov, Alexander N. Fomin

    Published 2022-04-01
    “…Determining the value of the heat flow density from the roof of the foundation is complicated by taking into account many processes occurring both in the bowels and on the surface of the Earth. Therefore, an integral approach was used in the calculations, allowing these processes to be taken into account with the help of conjugated structural-tectonic reconstructions. …”
