Abstract
-
Describes a complex association of pyroclastic, hyaloclastic and resedimented, texturally immature volcaniclastic facies associated with shallow intrusions, lavas and minor limestone, non-volcanic siliciclastics and ignimbrite. Primary igneous rocks indicate a predominantly mafic-intermediate parentage. Quench-fragmented hyaloclastite breccias are widespread and abundant. Shallow marine conditions for much of the succession are indicated by fossil assemblages and intercalated limestone and epiclastic sandstone and conglomerate facies. -from Authors
