THE MOTUR GROUP. 49 



On following down the Punghat (south of Jamye) and Sungun 

 rivers we get off the red clays on to Barakar sandstones and shales, 

 the change being very sharp at these points ; after the junction with 

 the Soonkee just before coming abreast of Saleye hill, there is a 

 run of pseudomorphous quartz rock across the river, and just opposite 

 the hill a wide trap dyke, beyond which there is more pseudomorphous 

 quartz and the sandstone near is much impregnated with silica ;. 

 immediately beyond this the boulder bed of the Talchirs is seen, evi- 

 dently faulted up against the Barakars by a continuation of the fault 

 seen in the Raneedoh stream, which passes obliquely right across the 

 outcrop of the Barakars, and has shifted these beds horizontally almost 

 along their strike for a considerable distance. 



The Moturs occupy the high ground below the trap to the north 

 of the Kanhan field of Barakars, till they are again faulted against 

 the Talchirs at the Pothia river for a short distance. 



Beyond this point the Motur-Barakar boundary becomes much less 

 well marked, as the red clays are much less developed and the inter- 

 mediate sandstones come in in greater force. 



The general dip of the Moturs is north to north-westerly and is 

 seldom high, being usually at about io°. 



The upper boundary of the Motur group I have not yet worked 



out, but the clays extend for some distance under

the trap of the Motur hills and are seen in the 



river by Bichberi south of Pachmarhi. This indicates a thickness of 

 about 2,000 to 3,000 feet at the most modest-computation, but it is 

 probably more. 



In the deep gorges, through which the Pench river leaves the trap 

 of the Motur uplands, the river has cut back, leaving the Moturs ex- 

 posed and near the village of Bolkheri I found a few fossil fragments 

 of plant stems ; this is the only place where I found any fossils in 

 these rocks. 



There is a small outlier of Motur clays and sandstone, at the 

 Outlier near Raje- highest point of the hills to the north of Rajega- 

 S aon - on (E. Lon. 78 if), near the Tawa river.
