100 FOYE. 



A. Renard (1888) in the report of the Expedition. Only three types 

 were noted : — 



hornblende andesite, 

 augite andesite, 

 biotite andesite. 



In 1899, Arthur S. Eakle (1899) described some of the igneous 

 rocks, collected by Alexander Agassiz during his voyage among the 

 islands. The types determined were: — 



diorite-granite, hypersthene andesite, 



augite andesite, hornblende andesite, 



augite-biotite andesite, basalt, 



augite-olivine andesite, olivine basalt. 



E. C. Andrews (1900) visited the islands in 1898 and in a report 

 on the "Limestones of the Fiji Islands" gave a brief description of the 

 volcanic rocks which he collected. 



In 1901, ^Yalter G. Woolnough (1903) made a journey across Viti 

 Levu, and, for the first time, found granites in place. He described 

 the following rock types : — 



granite, pyroxene andesite, 



quartz diorite, hornblende andesite, 



diorite, olivine andesite, 



augite andesite, porphyritic basalt. 



H. B. Guppy (1903), during his travels in Vanua Levu between 

 1896 and 1899, collected a large number of rocks which he carefully 

 described in his book concerning the geology of this island. 



N. D. Cochrane (1911), acting as Government Mining Adviser, 

 described briefly a large number of rocks from the islands. The chief 

 types noted were : — 



I. Sedimentary Rocks. hornblende andesite, 



redistributed tuff, mica andesite, 



tuffaceous marl, olivine andesite, 



limestone, hypersthene andesite, 



marble. trachyte, 



porphyrite, 

 gabbro, 



II. Volcanic Rocks. diabase, 



tuff, diorite, 



basalt, (piartz diorite, 



dolerite, hornblende granite, 



augite andesite, biotite granite.
