GEOLOGY OF SIND. 7 



From Runneekote to the banks of the Indus, in a direct line, no 

 rocks were seen, the whole surface being covered and concealed by the 

 alluvial pebble deposit. 



4. — Relations and classification op beds. 



The deposits of this portion of Sind were considered by Captain 

 Vicary^ to be the following in descending order : — 



1 . Conglomerate. 



2. Clays and sandstone. 



3. Upper bone bed. 



4. Sandstone ; fossils rare. 



5. Lower bone bed. 



6. Coarse arenaceo-calcareous rock witb Cytherea exoleta? and exaratai 



Sjpatangi : no Nummulites. 



7. Pale arenaceous limestone witli Hypponyces , Nurnmulites, and CJiaroidece. 



8. Nummulitic limestone of tbe Hala Hange. 



9. Black slates ; tbickness unknown. 



The first five are probably higher beds; indeed the first six are excluded 

 by Dr. Carter as Miocenef, but Captain VicaryJ states that the rocks of 

 the hills north-west of Kotree are in all respects similar to the non-nummu- 

 litic rock No. 6. Captain Vicary traversed this country very rapidly, and 

 the difficulty of procuring water prevented him from visiting the hills. He 

 mentions, however, the occurrence of " variegated clay abounding with 

 gypsum, but containing no fossils,''^ and again states that, between the 

 range of hills stretching north to Sehwan (Eri Hills) and the InduSj 

 " there are numerous low hillocks of aluminiferous clay,^^ and he mentions 

 his inability to ascertain the relations of these clays to the beds of the 

 higher ranges. In the hills north-north-west of Kotree he recognised 

 his No. 7, probably, in the beds so rich in marine fossils noticed by 

 me near Lynyan.

 In a note, page 743, however, he follows D'Archiac and Haime in classing aU beds below the 

 bone-conglomerate as Eocene.
