418 THE GEOLOGY OF THE NEW HEBRIDES, 



generalised section is given, whereb}' the outcrops on both tracks 

 to Laleppe are incorporated in the same section. The trip took 

 us a whole day's hard walking, and a considerable number of miles 

 must have been covered. Nevertheless, when plotted in a direct 

 line, it pans out as three miles only. 



The tirst mile inland passes over low fiat country of the nature 

 of recent raised reef and shore debris; beyond it rises gently for 

 |-mile to the village of Bartaleppe, elevated probably 400 ft. 

 above sea-level. Outcrops along this part of the track show it 

 to be underlaid by coarse-grained foraminiferal tuffs (99) of 

 doubtful age, either Miocene or newer. About 100 yds. before 

 arriving at Bartaleppe a narrow creek is crossed, in which well- 

 bedded Miocene tuffs and limestones (3) (106)"^ dipping 28° due S. 

 are encountered. After leaving Bartaleppe further outcrops of 

 Miocene (109) tuff beds appear for a height of several hundred 

 feet. Then comes a 20 ft. sill of augite andesite intersecting the 

 limestones along the bedding planes; the sill is overlaid by a 

 30 ft. bed of a hard white limestone; above this again, is quite 

 100 ft. of a granular foraminiferal limestone (4) (102) of Miocene 

 age, much resembling sandstone, and dipping 17° S., 40° W. 



We had now arrived at Laleppe; continuing to ascend we 

 passed over thick beds of coarse and fine mineral tuff8(5) capped 

 by foraminiferal limestones, the Lepidocyclina-Lithothamnion 

 limestone (6) (105) outcropping at the amil. Limestones (108) 

 continued to outcrop to the top of the hill, 1145 ft. On the way 

 down to Bartaleppe tine-grained grey submarine tuffs (7) (107) 

 with abundant Globigerina and pellets of pumice were met with 

 below the white limestone zone, dipping 14° S., 20° E. 



Note that the three dip readings taken in the Miocene series 

 differ very widely; this points to great local earth-movements, 

 contemporaneous with or subsequent to their deposition. 



Summarising the preceding observations, we notice as a 

 conspicuous feature of the geology of Malekula in the districts
