6. Upper red variegated Sandstones, grits, conglomerates and red 

 shales. 



7. Yellow, marly nummulite Limestone, reposing on bituminous 

 shales, indicated by the dark line in which a bed of lignite, from 3 to 

 5 feet thick, occurs. 



8. Miocene tertiary Sandstones, argillaceous Grits, Conglomerates 

 and red indurated Clays containing mammalian bones and teeth and 

 lumps of brown silicified wood. 



The above strata all dip to the N. N. W. at an angle of from 45° 

 to 50°.

 Shah. 



1. Alluvium. 



2. Eed marl with beds and masses of gypsum and salt, the 

 strata of the former being often bent, and contorted in a most re- 

 markable manner. The marl has been much disturbed, and presents 

 few or no indications of its being a stratified deposit, except towards 

 its upper surface, where it dips under the superior rocks. 



3. Lower red sandstone with grit and conglomerates. 



4. Greenish micaceous sandstones and shales. 



5. Grey Dolomitic (Magnesian) Sandstone, weathering of a fawn 

 colour. 



6. Upper red variegated Sandstones, Grits, Conglomerates and 

 clays. 



7. Brown calcareous Sandstone (Eocene). 



8. Eocene bituminous Alum Shales in which is a bed of inferior 

 lignite. 



9. Nummulite Limestone with irregular-shaped masses of grey 

 flint. 



10. Patches of miocene tertiary Sandstones, rapidly disintegrat- 

 ing ; contain mammalian bones, &c.

 of red and purple clay, impure rock salt and gypsum ; below it ex-
