Pseudomorphoses of calcite after ikàite are stellar rosette-like spheroid crystal nodules or clusters of up to 10 cm in cross size. These units are considered by many researchers as an indicator of low temperatures in a sedimentation basin (around 0̊C) [1—3]. They have repeatedly been found in Mesozoic and Cenozoic deposits of Siberia and the Russian Far East [1, 4, 5].
