The Lomaiviti Group is
among the geologicaly yungest in Fiji. The islands
formed less than 10 Million years ago through vulcanic
activity and resulting magma eruptions.
summary formation Lomaiviti Islands:
Ma (million years ago) there was a continious
melanesian arc including PNG, Solomons, Vanautu, Fiji
10 - 8 Ma
subduction that was SW orientated ie. the Pacific
plate was subducting under the indo-australian from
the NW-SW, switched direction ie. the indo-aus plate
then subducted under the Pacific.
8-4 Ma the New Hebridies
arc swung towards the SW and the Fijian platform was rotated
anticlockwise ~ 130°, during this period the fijian platform
was also extending and rotating along N-S and E-W orientated
strike slip faults. North Fiji Basin spreading
4-0 Ma Lau Basin opens and continued extension
without rotation. Mantle upwelling in Koro sea region.
Lomaiviti Group volcanos erupt, up welling of magma
forms the Islands Moala, Gau, Wakaya, Makogai, Vatu and the
