26 JONES: SOUTHERN COAL-FIELDS OF SATPURA GONDWANA BASIN. 



Immediately to the north, a trap dyke running east and west, and about 30 

 yards broad, crosses the seam. This great mass of igneous rock has tilted up the 

 seam slightly to the north, but does not appear to have much affected the coal. 

 The seam re-appears just north of the dyke, dipping north, at first at an angle of 

 about io°, but immediately beyond, at a much lower dip, varying from about 3 

 to 5 . For about 150 yards from the dyke, the outcrop of the coal seam occupies 

 the bed of the river ; then massive sandstone comes in, apparently brought up by a 

 small fault, striking nearly east and west, with an upthrow of about 20 feet to the 

 north. The sandstones dip to north- io°- east at about 5 , and, upon them, about 

 30 yards further, the coal seam re-appears; that is to say, coal of great thickness 

 comes in, and it has every appearance of being the same seam. If not, two very 

 thick seams must here occur, one above the other, and separated by only a few 

 feet. The coal seam continues to crop out in the bed of the river for a short dis- 

 tance, when it is covered by the overlying trap, which forms both the bed of the 

 stream and the hills on its banks. This trap continues for a considerable distance 

 up the river." 



The coal is also seen in several spots to the west. In the Jobe 



stream south of Dighawani, I found fragments

stream, but I could find no further indications of 

 coal at this spot. In the Pathajhora stream to the east of Dighawani, 

 just above the crossing between Dighawani and Setia (Saindra), clayey 

 shales with carbonaceous layers occur dipping to north-20°-east at 

 io c ; following down the stream some way below this there is a thin 

 band of coal dipping north at 8° with shale above and below it, the 

 shale dipping at 20 to north. The shale and sandstone can be traced 

 for some distance down the stream, till just above its junction with 

 the Pench, at which point the red clays of the Moturs are faulted 

 right against the coal and shale. 



In a small watercourse, north of this stream, the shale and coal 

 are again seen extending nearly down to the Pench. 



In the next watercourse to the north the coal occurs in close 

 proximity to the trap dyke mentioned by Mr. Blanford and to the 

 south of it.

 Nala and distinguished by a Pipal tree which grows close to it on 

 the north side (the only one of these small watercourses north of
