VINDHYAft SEEIES. 13 



By looking- at the map, it will be seen that there are several lines of 

 disturbance, and that the sandstones are divided by a band of limestone 

 into two branches. The western branch sweeps round by Sindola 

 and terminates at Kiirli. The rocks are considerably indurated, and 

 assume a quartzite character near the outer boundary ; and near Sindola 

 they are much jointed. Towards Paramdeo they form .a high scarp. 

 Several bands of conglomerate occur, containing" pebbles of haematite, 

 from which the iron formerly made at Yenak was obtained. One of 

 these bands is 9 feet broad in places. Where the road from Yenak to 

 Sindola crosses a low portion of the hill, some of these conglomerates 

 have been worn down, and a more recent laterite bed of considerable 

 extent formed of the debris. 



Vindhyan sandstones appear also in Sideshwar hill, 8 miles south of 



Rajur, in the Nizam's dominions. The upper beds

consist of hard, coarse grits and sandstones, very 



conglomeratic in places; the lower are generally much finer in texture, 



and often highly vitreous. They are all more or less colored by 



iron.

of flaggy limestones. They are very fine-grained j

with a somewhat nodular structure, and much joint- 

 ed. When they weather they split up, like the Talchir shales, into small, 

 thin, discoidal fragments, and an isolated outcrop of them might readily be 

 mistaken for that series. Their usual color is some shade of red. In the 

 northern part of the field they appear near the village of Dongargaon, 

 about 1\ miles from Warora. A considerable amount of crushing has 

 taken place in the neighbourhood, and the character of the shales is al- 

 tered, the disturbance having rendered them very hard and compact. 

 The Wardha Valley State railway crosses the Dongargaon river exactly 

 opposite to the village, and the shales afford an excellent foundation for 

 the piers of the bridge.
