EASTERN Pl-ATEAU. IfiSc 



From tlie prevalence of coal}' beds iu the upper part of this section, 

 which is unusual iu the group, it may be doubted whether the upper 

 portion with a separate bracket is not a local representative of the coaly 

 shales beneath the nummulitic limestones. 



In the Kiisak " beat/^ westwards of the Jutana one, the salt-marl is 



even more largely exposed than in the latter, 



Kusak'beat.' and two outlying portions of the overlying rocks 



form hill-groups surrounded by it. In the upper 



part of this marl, at the western side of the " beat/^ there are strono-

purple bands, and also a sort of gypseous pseudo-breccia. Salt is seen 

 „ ., in several places, even near the mouth of the 



western of the two streams which drain the 

 *' beat :^' and there are several old mines within its valley. In one of 

 these, Dr. Warth found a seam of salt (with some marly bands) one 

 hundred and fifty feet in thickness, dipping at a high angle to the 

 west-north-west.* 



Other old mines occur also in the eastern portion of this " beat,^* 

 mostly inaccessible, and the natural exposures of the salt by streams, 

 &c., show little that is instructive, any stratification marked by the 

 gypsum being contorted. 



The two isolated hill-groups referred to show the series as high as 



the magnesian sandstone, the rocks being much
