70 WYNNE : GEOLOGY OP THE SALT KANGE IN THE PUNJAB. 



The whole of this great series^ from the red marl up to the post= 



tertiary group^ presents a general and regularly 

 Conformity. . -n • 



successive parallelism of stratification, each group 



succeeding the one it rests upon without the intervention of any marked 



traces of erosive action.''^ In a few isolated cases the upper surface 



of the highest carboniferous layers has been found locally rugged, as if 



the upward succession were less regular at that horizon, but in its 



general aspect it presents no exception to the rule.f 



Haematitic layers have been observed in some instances to mark the 

 junction of some of the upper formations, both where the succession 

 indicates the greatest irregularity and where it exhibits the least. 



One break, indicated by derived pebbles of the lower rocks, at the 

 junction of the tertiary sandstones with the nummulitic limestonej 

 accompanied by as much parallelism as elsewhere, will be noticed 

 further on. 



Saline Series. 

 Hed Marl : Gypsum : Hock-salL 



The saline series is distinguished by the predominance of marl, in 



colour bright scarlet to dull purple, containing 

 Salt Marl No. 1. , , , i ^ i- -, -, 



the rock-salt, gypsum, and some subordinate dolo- 



mitic layers, all forming together the lowest member of the series. In 

 every section and every glen where the section is seen, the , gypseous 

 marl may be clearly observed passing beneath the next group and 

 underlying all. It is always succeeded by dull earthy sandstones or con- 

 glomeratic beds, and always presents the same peculiar aspect. 



* In the outer Himalayas, at Sirban mountain, near Abbottabad, there is marked 

 unconformity of the Trias, &c., resting upon the supposed Silurian slates, 



t This unbroken passage of the rocks from Palaeozoic to Mesozoic formations, the 

 distinction being chiefly marked by the fossils alone, seems also to characterise the succes- 

 sion in the Himalayas as shown by Dr. Stoliczka's Sections and his paper, — see Mem.
