Section 12. — The Kanta. 



In this part of the country a considerable change in geological 

 structure is observed. The greater portion of the tertiary rocks seen to 

 the west disappears ; the uppermost group^ however^ continues with some- 

 what different character, partially separated from the traps by a narrow 

 band of the sub-nummulitic group which dies out to the eastward. 



The stream sections here were with few exceptions unsatisfactory, 

 their broad sandy beds with low or sloping banks exposing only here 

 and there small outcrops of nearly horizontal rocks. 



In the neighbourhood of Bit Assambia the trap flows are frequently 

 much decomposed, and their upper bed is of a 



Bit Assambia. 



peculiar greenish ashy variety with hsematitic 

 strings immediately succeeded by the laterite, which may be found in the 

 neighbouring streams, and rises with a small escarpment running towards 

 the village of Poonree. 



Eastwards of Bit Assambia these lateritic beds form a low anticlinal 

 ridge running in that direction, and where it reaches the Furradee stream, 

 the mottled laterite having a pseudo-breceiated form overhes red-yellow 

 and white unctuous aluminous beds with strong saline efflorescences. 



South-west of Bit Assambia, near the village of Gooniassir, the 

 lateritic beds are succeeded by raggy shales, overlaid by calcareous 

 brownish sandstone with numerous annelid tubes. Above these are 

 whitish muddy and rusty shales dipping to the southward, so as to under- 

 lie thick light-colored sands and sandstones at the village, amono- which 

 are harder fine grained beds used for ornamental building. 



Near Burra Assambia Httle rock is seen, but some mottled clays with 

 grains of quartz were found in the river south of the village, underlying 

 soft sandstones and rubbly earthy rocks.
