mentioned are only results of the alteration of hornblend and epidote. 



About 3 miles north-west of Jobut, and nearly due south of Kunas, 



_ , , ^ near Jeri. the red beds are distinctly brought 



Fault boundary near 



Jeri. against the metamorphics by a fault running 



north-west to south-east. The Bijawurs here terminate, as usual, in a 

 low scarp, on the top of which the red jaspery beds are met with, dis- 

 tinctly nearly horizontal, their b6dding being well seen in a small glen, 



cut by a stream which issues close to Jeri village. 



Red beds, &c., near ^ ° 



Jeri. The uppermost bed, a red jaspery rock with white 



veins, is alone seen up the glen, the bottom of which is concealed by a 



deposit of carbonate of lime. Below the red bed, on the scarp bounding 



the Bijawurs, are calcareo-siliceous beds, sandy in appearance, abounding 



in strings and nodular lumps of quartz, and having a remarkable 



resemblance to some of the calcareous cretaceous rocks. They are 



similar to the beds already mentioned near Jobut. These sti-ata, instead 



of beino horizontal, like the red beds above, are more or less contorted, 



and, especially towards the bottom of the spur, they are nearly vertical, 



their strike being parallel to that of the metamorphics close by. 



The sudden apparent change in the strike from the horizontal red 



„ rock above to the vertical calcareous rock below

 formity between red beds joig-lit be accounted for by any one of three ways, 

 and calcareous rock be- ° ^ ^ 

 neath. J The rocks may be unconformable; but if they 



were, the separation would probably be more marked and distinct, and it 



is improbable that over a considerable area, one form of rock alone should 



underhe the jasper, as appears to be the case, the same calcareous sandy 



beds having already been noted beneath the red beds north-east of Jobut, 



3 or 4 miles from Jeri. 2. The beds may be bent over near the boundary 



fault. This is more probable, but as the downthrow is to the north,
