The crystallisation-deformation relationships and mineral parageneses observed in the schists, gneisses, and metabasites of the ChMC allowed us to advance the tectono-metamorphic evolution during the HP-LT subduction--related metamorphism and later retrogression to greenschists-facies conditions.
Their distribution has been controlled by a combination of factors such as temperature, pressure, hot aqueous fluid circulation and rock's chemical composition (Walker, 1960) A study of the Beinn Edra Group lavas by King (1977) revealed the occurrence of similar parageneses of zeolites to those of the analcime-natrolite zone defined by Walker (1960).
Parageneses consist of clinopyroxene, plagioclase, ti-magnetite and of scarce occurences of pseudomorphosed olivine.
