La Cruz Formation is made up of olivinic basalts, diabases and 2-pyroxene andesites. The Grifo Alto Formation corresponds to andesitic intermediate rocks and ignimbrites with xenolites aof andesitic and granodoritic rocks. Cataclastic metamorfism has been recognaized in Delcias creek. Diabase dikes cross the sedimentary sequence. Hornfelses related to the Escazú stock belong to Peña Negra and La Cruz formations. |
