282 WYNNE : GEOLOGY OF KUTCH. [PAET II. 



Near Bait the river bank of 50 feet exposes sub-recent deposits of 



pebbly and gravelly detritus more or less strati-

conglomeritic and sandy beds of the upper tertiary group lying nearly 



horizontal. 



In the Laija river, nearly horizontal and rolling, faintly mottled 



earthy calcareous and sandy beds with layers of con- 

 Xiaija. 



Crete extend from the latter village to Rajera and - 



Bun'a Ruttria, and some of the fossiliferous beds of the underlying 



group occur at Badye, but are not traceable beyond a few miles to the 



eastward, being apparently overlapped by the upper tertiary beds.

The upper bed of the ordinary stratified traps near Chota Ruttria 



is a thick, soft, greenish amygdaloid, weathering

rapidly and having an uneven suriace. It is 



overlaid by strong red laterite and soft red shales, with small pockets of 



the white unctuous volcanic aluminous rock so frequently observed 



beneath the laterite. The strong lateiite here is of a brick-like and 



pseudo-breceiated appearance. The boundary between it and the traps is 



most irreo'ular, and the soft beds so completely weathered down that the 



relations are obscure. 



The laterite is succeeded by a most heterogeneously assembled group 

 of lenticularly and falsely bedded coarse, white, and conglomeritic sand- 

 stones with large grains of white quartz and pale purple, unctuous, 

 mottled aluminous layers and lenticular masses, quite similar in character 

 to the usual volcanic ashy beds associated with the laterite. In one of 

 the coarse beds some ferruginous markings like fossil wood were 

 observed near a place where small accumulations of dark shales with 

 thin, crisp, ferruginous layers were interstratified.
