252 Report on the Geological Structure of the Salt Range. [No. 3. 



the red sandstone until we reach Jutana, where it occurs in great 

 quantity and includes large stratified masses apparently of salt, 

 along with broken up beds of gypsum. No salt is seen in the marl 

 East of Jutana, though wherever it appears, its surface is covered 

 with a saline efflorescence, and all the springs which issue from it 

 yield a strong brine. 



From this point it may be uninterruptedly traced to Pind Dadun 

 Khan, in the neighbourhood of which it yields a very large amount 

 of salt, and from thence with but a few breaks on to the Gredi Hills 

 near Moosakhail, between which place and Eooreekhail it is not 

 seen. Here it again crops out and yields salt, and may be traced 

 westward for some two or three miles into a ravine, which separates 

 the Lukrukkie from the Majooch Hills. It then disappears and does 

 not again, as far as we are aware, crop out, till near Maree on the 

 Indus, where it forms an isolated ridge overhanging the river, along 

 the right bank of which above the town of Kalibagh it is extensively 

 developed, the salt appearing in immense stratified masses in the 

 marl. Except for a few miles up to the Loon Nullah, which enters 

 the Indus opposite Maree, we have not traced the marl northward, 

 but probably the same formation yields the salt obtained at the 

 mines in the Kohat district, which from the repeated attacks of the 

 hill tribes have gained considerable notoriety. 



At Maree and Kalibagh, the marl appears to have been subjected 

 to great disturbance, and the red sandstone strata, which in other 

 localities are immediately superior to it, seem to be wanting entirely. 

 At Maree a few Tertiary sandstone strata, may be seen dipping as 

 it were under the marl, and on the Kalibagh hill it seems entirely 

 covered by Tertiary conglomerates and sandstones. As there is 

 distinct evidence of a great upheaval and fracture of the rocks at 

 Kalibagh, it is not surprising that the salt marl should appear to 

 have suffered in the general disturbance, and to have as it were been 

 forced up through the rocks, which in the regular order of things 

 intervene between the Tertiary strata and the marl. 



Its relation to the Tertiary rocks might induce the supposition, 

 that at Kalibagh the marl was of Tertiary age, but its general ap- 

 pearance and mineral character are identical with the rock to the 

 eastward, and leave no room to doubt that it is of the same age.
