โœฆ Synopsis

Coronas which have been developed between olivine and plagioelase in Preeambrian gabbroic rocks from Thessaloniki, Greece, have been studied. These consist commonly of (olivine), clinopyroxene, amphibole (plagioclase) and rarely of (olivine) orthopyroxene, clinopyroxene amphibole (plagioclase) assemblages.

The results of the electron-probe microanalysis of the above constituent minerals are presented.

The formation of these coronas by regional or thermal metamorphism is unlikely, but an origin by a two-way diffusion of material across the olivine and plagioclase interface is proposed.

Chemical composition of the phases occurring as corona structures in the Thessaloniki gabbros are subjected to algebraic method of treatment following Korzhinskii [13. The analysis reveals that the mineralogical reactions responsible for the growth of the corona structures were possibly allochemical
