138 WYNNE : GEOLOGY OF THE SALT EANGE IN THE PUNJAB. 



The olive group is apparently only locally developed and not thick in 



the neighbourhood, yet a large syenitic block, or 

 Large erratic block. 



boulder, supposed to have come from it, which 



was observed in the stream bed above the fall, measured six feet four 



inches in length. 



Following the tributaries of this stream north-eastwards, the head of 



a ravine is reached, which leads into the Bunhar 

 - Coal locality. 



valley near Kotal Kund. High, tertiary sandstone 



and conglomerate hills rise on either side, their beds dipping to the 

 north-north-east at 50° and 60°, and just below these rocks is a band of 

 nummulitic limestone overlying dark coaly shales, with a bed of good coal 

 three feet six inches thick. Underneath it some sandstone occurs, and then 

 a band of bluish grey shale, which rests directly upon the red salt-erystal- 

 cast zone. This is the Bhaganwala coal locality, the " mines " being repre- 

 sented by a few small excavations in the bank at the side of the stream. 



The ground is bad and the ravine steep and so narrow that a fallen 

 mass from the limestone had almost blocked it up ; but the flood water 

 had found a passage, through which the tape was carried, partly beside 

 and partly beneath the block. The following is the section measured at 

 this place, which is about two miles in a straight line north-east of 

 Bhaganwdla. (See fig. 15, PI. XIV.)
