SOUTHERN KHIRTHAR, BHIT AND BADHRA RANGES. 115 



hollow occupied by higher beds. To the south of the Badhra range also, 

 as be} r ond the southern extremity of that of Bhifc, there is a tract of 

 upper tertiary beds faulted against the eocene limestone of the Khirthar 

 range. 



From the northern extremity of the Badhra range, Nari, Gaj, and 

 Upper tertiary beds Manchhar beds extend in succession to the Manch=

extremity of the lake and form a long promontory stretching northwards 

 into the alluvium. This promontory extends past Chhini, as far as Mir 

 Khan, but the rocks are only seen here and there, and are much concealed 

 by sand and gravel. There is, however, a very fair section exposed on the 

 road between Shah Hassan, at the western end of the Manchhar Lake, and 

 Pir Gazi. The beds form an anticlinal, and this is interesting, because 

 it shows how local these folds are, for there is no corresponding undula- 

 tion in the Gaj outcrop to the southward, and yet the roll in the Man- 

 chhar beds must, of course, affect the underlying Gaj. Such a feature as 

 this is, of course, in favour of the view that the apparent unconformity 

 of the Gaj on the Nari beds a little farther west in the Angyi valley is 

 not real. 



Near Shah Hassan grey sandstones are seen, but to the westward con-

the conglomerates are pebbles of both Khirthar and Nari rocks, the 

 Alveolina and nummulitic limestone of the former, and the characteristic 

 ferruginous bands of the latter, both occurring in plenty. But by far the 

 largest number of the pebbles consist of a bright yellowish-brown calcare- 

 ous sandstone,, speckled with black, and evidently derived from the Gaj 

 beds. 



It may fairly be assumed that, despite the prevalence of grey 

 Unconformity between sandstone, so characteristic elsewhere of a low 

 Gaj and Manchhar. horizon in the Manchhar group, all the conglome- 



rates here seen are of Upper Manchhar age; for wherever the whole 

 section is exposed, no Khirthar, Nari, or Gaj fragments have been noticed
