Abstract

Bodies of rodingite rocks have been discovered in the Jurassic serpentinized ultrabasic rocks in the 'Rzanovo nickel mine. Electronic microanalysis and microscopic analyses of rodingites determined the presence of garnet (hydroglossular-hibschite), diopside, chlorite, iron hornblende, actinolite, vesuvian, pumpellyite and prehnite. Rodingites display gradual transition to associating gabbropegmatites indicating similar chemical composition, the only difference is that rodingites are enriched in CaO, and poor in MgO and FeO. The pumpellyite + actinolite + chlorite assambJage and the structural-textural characteristics are indicators that rodingites were affected by regional metamoIphism in conditions of pumpelite + actinolite assemblage at temperatures from 250 to 300°C and pressures of 2.5 to 3 kb.
