A series of coral reefs with associated atolls lies on a 
near and subparallel arc extending beyond not only the 
group under discussion but also beyond the New Britain 
Group. This indicates a geographical unity for the Solo- 
mons, New Britain, New Ireland, and the New Hebrides. 
as The Fiji Islands consist of four main belts, namely 
(aa) the western or larger islands of Viti Levu and Vanua 
Levu, (bb) the extinct and dissected volcanic masses lying 
immediately to the east and extending from Tavinni to 
Kandavu, (cc) the raised coral reefs of Lau or Hastern Fiji, 
{dd) the outlying atolls of Eastern Fiji. 
These belts converge to the north. The eastern member 
which is composed of raised reefs and atolls is longer than - 
the belt of the main western islands. This is a feature 
common to the island groups. 
(aa) The large western islands have nuclei of old rocks. 
The Kainozoic deposits which overlie these older rock 
types are bedded and have been subjected to folding. The 
principal types included are “‘soapstone,’’ well bedded 
limestones containing corals, and volcanic material. These 
apparently are of Miocene Age. | 
A great barrier reef surrounds the main islands of Viti 
Levu and Vanua Levu. 
Klevated coral reefs of Pleistocene Age, however, have 
not been recorded from heights more than a few feet above 
sea level. 
The marked dissimilarity which exists between the coral- 
bearing limestones of Tertiary Age and the Pleistocene 
coral reefs is discussed below. The absence of Pleistocene 
coral reefs from the continental masses and the large 
western islands of the individual groups of islands is dis- 
cussed elsewhere also.
