130 BLANFORD : GEOLOGY OF WESTERN SIND. 



trap is interstratified with the sandstones ; and if so, it is at a con- 

 siderably lower level than the flow in the preceding section at the base of 

 the Ranikot group. Close to the trap, and apparently underlying it, 

 there is a very fossiliferous bed containing Corbula liarpa, an oyster re- 

 sembling 0. flemingi, a Turritella, a small coral, and two echinoderms, 

 one of them a Ciclaris. 



East of the fault, the Khirthar beds come in with a reversed dip 

 only a small thickness is exposed, and then Manchhar beds appear 

 dipping at high angles. 



The Deccan trap does not extend much farther north than Jakhmari, 



both it and the underlying beds disappearing

beneath higher strata within less than a mile. 



Under Kharguzani peak, about 2 miles north-east, only Ranikot beds 

 are seen between the Tiytfn range and the fault. The only remarkable 

 point about the section at this spot is that, east of the fault, resting 

 upon the Khirthar limestone, some Nari beds are seen, ferruginous brown 

 limestones with the characteristic Orhitoides papyracea. The dip of the 

 Khirthar limestone here also is reversed. The Manchhar beds to the 

 eastward are faulted against the Nari beds, and dip about 60° to east- 

 by-south, and the Khirthar beds underlying the Naris, but with their 

 dip reversed, as if overlying, are faulted against Ranikot beds. The 

 uppermost 200 or 300 feet of the Manchhar group consist of conglome- 

 rate overlying soft earthy and sandy beds, yellow, bluish-grey, and red 

 in colour, and these pass down into soft grey sandstones, with conglome- 

 rates and argillaceous grits. Bones and teeth of mammalia are not rare, 

 and from this neighbourhood many specimens were procured, 1 especially 

 of the peculiar ungulate types, such as Hyopotamus, Ant7iracotherium } and 

 forms allied to Merycopotamus. 



To the southward from Jakhmari the outcrop of the cretaceous beds 



Cretaceous beds south below tne tra P becomes broader, and the anti- 



of Jakhmari. clinal ridge of cretaceous sandstone, the lowest 



strata exposed, becomes higher, but still the infra-trappean (cretaceous ?)
