Descripción
The finding of peperite breccias on Marambio Island allows to confirm the existence of at least two different pulses in the instrusion of basaltic dykes within the James Ross Island Volcanic Group. Two important bodies of peperites were recognized at Filo Negro and Geoantar hill. They were formed by the intrusion of basaltic dykes in the unconsolidated Paleogene sediments of Sobral Formation. The breccias are composed of vesicular glassy fragments, and volcanic and sedimentary lithic constituents in a sand matrix. The intrusions were probably emplaced at very shallow depth and are possibly related to a younger volcanic pulse, dated at 1.3 Ma. © 1997 Asociaciôn Geolôgica Argentina.
