The transitions near Marai are profusely veined with gneissose 

 granite throughout the low ground, these grow

more abundant towards the granite outcrop of 

 the Sitkuri plain, the boundary between the transitions and crystal- 

 lines being very indefinite. In the hills west of Shahargar no intru- 

 sions were found, a fact which suggests that the existence of these 

 hills is due to the greater resistance of the rocks of which they are 

 composed/as compared with those of the low ground which have been 

 penetrated by veins of the felspathic readily decomposable granite. 



Further to the east, near the Samdin and north of the red shale 

 outcrop, the transitions are represented by green hornblendic 

 schists, and some bands of jaspideous quartzites. 



South of the outcrop of the red shale series the transitions are 

 free from granitic intrusion. There are banded quartzites of the 

 Bijawar type between which and the scarp of the Kharara hill are 

 phyllites and slaty beds, some of which are red in colour. 



Within the transition area a conspicuous scarped hill is rising 

 Doubtful exposure near over, and to the east of the village of Shahar- 

 gar is capped by a hard conglomeratic quart- 

 zite. It is an isolated exposure in a very much disturbed region, and 

 there is nothing to show which of the horizons, at which similar rocks 

 are found, it belongs to. 



The Kharara outlier of upper Vindhyan rocks forms an elevated 

 The Kharara outlier of range of hills, more or less plateau-like on its 



upper summit, which has a length of about 12 miles 



and a breadth of from 1 to 4 miles, bounded for the greater part by 

 prominent scarps. It derives its name from the village of Kharara 

 situated about the centre of the broadest part of the outlier, but not 

 as it happens, on the upper Vindhyan outcrop. This village has 

 given its name to the Kharara station of the Great Trigonometrical 

 Survey, situated on the highest peak of the range, on a hill which is 

 locally known as Dubhiabar. 



The Dubhiabar hill is composed of nearly horizontally bedded 

 sandstones, resting on highly inclined schistose slates, the bottom
