Ground ice in the sedimentary rocks and kimberlites of Yakutia, Russia

The formation of cement (pore) and intrusive ice in the frozen rocks of the central part of the Yakutian diamond-bearing province is considered. Cement ice is best developed in the sedimentary rocks and kimberlite pipes. Intrusive ice is formed only in areas of considerable tectonic disturbance. The geochemistry of the ground ice is the result of cryogenic processes that cause salt differentiation during water freezing, together with natural solute concentration and cryogenic mineral formation.
