SIARWAT AND KHASOR HILLS. 65- 



Spirifem, Fusulina, &c, the" whole underlying- lighter-coloured crinoidal 

 limestone. These beds belong apparently to the lower, but not lowest part 

 of the group. 



At the northern end of the scattered village of Kiri, just at the base 



of the hill, there are some curious highly inclined 

 Kfri; 



sands, clays, and recent conglomerates quite like 



local river drift, but dipping to the southward at 50 9 . It is rather difficult 



to account for such beds as these having so steep a dip ; they are situated 



rather too high to be very recent river deposits of the Indus, and may 



perhaps be accounted for by supposing this river to have cut away soft 



deposits at the mouth of a ravine for a considerable depth, and the newly 



forming ones to have filled the vacancy too rapidly to assume any other 



than a steep angle of rest. 



The possibility of beds, particularly stream deposits, being formed at 

 this angle, would have an important bearing upon the argument as to 

 mountain disturbance derived from the tilting of such strata as the post- 

 tertiary conglomerates near Kalabagh (see page 19). y 



About Kiri Khasor the lower beds of the carboniferous appear to be 

 chiefly crinoidal gray or white limestone, also bands of white calcareous 

 sandstone or decalcified sandy limestone. At the first benches on the 

 hill sides are contorted dark sandy Fusulina limestones, and over them 

 sandy crinoidal or cherty limestones with Corals. At the top of the ridge 

 crinoidal beds are chiefly seen in the cliffs; overlaid on the north- 

 west slopes by sandy limestone with Goiiiatites, Belleroplion, and 

 Denlalium. 



In this sandy limestone near the hill top I found a part apparently of 

 a rib-bone, also part of another bone, both of considerable size ; the 

 latter may have been a portion of a spine. 



A little higher up in these sandy beds a finely preserved Pecten and 

 an Aulosteges occur. 



Resting upon these upper carboniferous rocks arc 150 to 200 feet of
