40 EUNDELCUND. 



both, cutting the pebbles in the conglomerate : this is immediate^ over- 

 laid by strong green grits, with same strike and dip, about 30° to 

 S.W.. Here then is a section very similar to that under Sanodo, but the 

 conglomerate identifies itself closely with the crystallines, though it is 

 undoubtedly at the same time a Bijawur rock. But the same difficulty 

 arises here as already in the Kane section ; can it be called the bottom-rock ? 

 That amorphous rock on which it rests may either have been a hard rock 

 when it contributed the bond to this conglomerate, or it may have been 

 an unconsolidated accumulation of peculiar debris, afterwards made 

 crystalloid. 



At Barata there is a rock which further betrays the origin of this 

 zone of crystallines, although it hardly throws any light on their con- 

 nection with the Bijawurs : it is a ribboned schist of most regular lamina? 

 of dense, black iron oxide, and of clear quartz ; it weathers out in a 

 decided, narrow ridge, underlying at 80° to N., with a steady strike for 2 

 or 3 miles ; it is seen again in the river, whether a distinct bed or a 

 faulted or folded repetition, I cannot say. 



The Bijawur junction is not seen in the Dessaun, but the rocks associa- 

 tion with this schist are worth noticing. One has to go down to Jasounda 

 to get at a sound, normal granitic rock ; there, there is a well crystallized 

 syenite, weathering in huge spheroidal masses ; after a blank space this 

 is succeeded by a fine eurite, which soon becomes associated with a 

 coarse pegmatite, or rather, pegmatitic granite — hyaline quartz, white 

 and pink felspar, and white mica. These two rocks are so irregularly 

 mixed that there is no saying that either contains the other — the next 

 rock is a dark crystalline amphibolite, heading apparently N. E. — S. W. 

 after about 20 yards of blank section there is a ridge of ribboned schist, 

 dipping at 70 to N. W. — here as at Barata there are small and sharp 

 contortions among the laminae, but the general strike of the beds is very 

 steady ; they show for about 100 yards, some being purely siliceous; 

 above them pegmatite rock 20 yards, then more of the dark trap; blank
