WYNNE : GEOLOGY OF KUTCH. [PAllT il. 



Section I. — Parkur Nuggur. 



The bold tills of Kalinjur and those around Nuggur consist of red 

 syenitic granitoid rock, great masses of which rise abruptly from the 

 sandy plains around. It is a homogeneous rock with a foliated ap- 

 pearance on weathered surfaces only^ scaling off from large bosses and 

 hollows. A few divisional planes nearly horizontal and about 12 or 1 5 

 feet apart are visible in one part of the hills. 



A large elvaa dyke on the north side of the range runs north-35°- 

 westj and among the hills a lump of basaltic trap was observed, also a 

 piece of hornblendic diorite. No schistose rocks were observed in the 

 neighbourhood of these Kalinjur hills. 



In some places bedded sand and syenitic gravel abut against the 

 syenitic cliffs to a height of 200 feet. No shells were detected in this, 

 which, although uncemeuted rock, may be equivalent to the sub-recent 

 concrete of other places. The spurs and projections in which it is 

 seen afford on a small scale good illustrations of the denudation of hills. 

 The alluvium occupying the lower ground is in places tough, lumpy 

 and kunkury.
