22 JONES SOUTHERN COAL-FIELDS OF SATPURA GONDWANA BASIN. 



This gives an area of a little over one-eighth of a square mile over 

 which coal is known to exist at a short depth below the surface, 

 while at one point its thickness is known to exceed 4 feet 9 inches. 



Besides this seam of coal there is an outcrop of carbonaceous shale 

 in the stream to the east of the village below a white sandstone, 

 which was being quarried at the time of my visit for building 

 purposes. 



II. There is also the outcrop of a second seam of coal about half a 

 Outcrop of another m ^ e west-north-west from the village further up 

 seam - the same stream. The section here seen in the 



stream in descending order is :—

 Mottled sandstone . . . . . . . .20 



Mottled grey carbonaceous shales with coaly layers . . .18 



Mottled red shales with plant impressions . . . .04 



Grey clayey carbonaceous shale with thin bands of coaly matter 1 6 

 Coal : total thickness not seen, the bottom being covered by 



water, but Major Ashburner gave it as . . -30 



Major Ashburner sank a shallow pit through this coal, north of the 

 stream, and found it to be 3 feet in thickness. The dip is very slight 

 and to the north, this is a distinct seam from the one found in the 

 wells and is above it. 



Hirunbhutta: A short way above the village of Hirunbhutta, on 

 the right bank of the Mandla stream, and just below the point where 

 the trap comes in, there is a 10-foot bed of carbonaceous shale dip- 

 ping at two or three degrees to north- io°- west; there are 2 inches of 

 coaly matter in this shale. The shale is overlaid by a white compact, 

 rather flaggy, fine-grained sandstone which very closely resembles the 

 sandstone above the carbonaceous shale in the stream to the east of 

 the village of Sirgora. Taking into consideration the fact that the 

 general dip in this field is north to north-west and seldom exceeds io°, 

 it is not unlikely that these are two outcrops of the same bed of car- 

 bonaceous shale. This shale was discovered by Major Ashburner 

 subsequently to Mr. Blanford's visit in 1866.
