| Abstract: | GLORIA side-scan imagery from the northern North Fiji Basin reveals modern and relict sea-floor fabric. The South Pandora Ridge is marked by steep escarpments and small rift basins, but no recent volcanism. The northern and eastern limbs of the 16°58 S, 173°55E triple junction are marked by rift grabens flanked by steep escarpments, but little recent volcanism is apparent there. At present, there is no well-organized spreading system in the northern North Fiji Basin; extension and shearing are occurring within narrowly confined areas. It is uncertain how these areas relate to one another and fit into the regional tectonic framework. |
