Coronite

In the context of the upper slice of the Sobrado unit, the presence of high-P granoblastic granulites and the low Na contents of clinopyroxene in the coronites indicate that the latter represent arrested stages during transformation to granulite.

Four stages in the evolution of the Allalin gabbro can be recognized: […] 2. Coronites, with olivine or its pseudomorphs surrounded by garnet rims. Plagioclase in these rocks is pseudomorphed by jadeite-bearing assemblages.
