270 WYNNE: GEOLOGY OF KUTCH. [PAET JI. 



Below the shales is a rubbly shelly rag overlying yellow marls, both 

 containing Turritella angulata, Ostrem, Placuna, Spondylus, and other 

 bivalves. 



About a mile further west in another ' takree' (small hill) called 

 ' Eyera bett' similar rocks contain the same fossils, together with 

 Scalaria, Natica, Cyprea, Cidaris, spines and crustacean fragments. All 

 these beds form somewhat high ground, extending east and west with 

 a broken escarpment on their outcrops facing northwards. 



In the neighbourhood of Soojapoor, the country is traversed by large 



streams with many deep tributary nullahs exposing 

 Soojapoor. 



disconnected sections through the gently undulating 



rocks which have a general tendency to dip southward. The following 

 beds were observed, the thickness not being always apparent, and the 

 succession of some bands doubtful, but all belonging to the same group. 

 Some of the exposures exhibit the very variable nature of the deposits, 

 apparently the result of accumulation by strong currents alternating fre- 

 quently with more tranquil conditions : —

 fragments of the same rock and a few oysters. It occurred in 

 the river bank only and may be unconformable),
