South of Eyware is a scarp of these lateritic beds, at the base of 

 _, ^, -,1 which much decomposed trap with a laminated 



Southern and eastern ^ '■ 



sides of hills. structure occurs. Interbedded with the laterite 



is a dull speckled sandstone underlying a layer of rich ii-on ore, above 

 which white beds overlaid by laterite dip to the south-east. The low 

 angle of dip carries these sub-nummulitic rocks over a wide space, but 

 they are eventuallj^ lost sight of under the wide tract of alluvium which 

 occupies most of Chorar. 



On the south side of the island some of the superficial deposits,

been coloured accordingly, although from the absence of fossils the fact 

 is somewhat doubtful. A little flat topped hillock in the Runn on the 

 road fi-om Peeprala to Adeysur presents the following section in natural 

 order : — 



Seds, horizontal, depth SO feet.

ahundant fragments of wood and one of bone.

I gypsum, some 2 inches thick. 



2. Argillo-arenaceous shale, also gypsiferous.
