Cross fault. 



Two more instances will be subsequently pointed out in the present 

 field, in which the existence of springs has confirmed the inference 

 previously arrived at that a fault occurred. In one case there was some 

 obscurity and doubt as to whether the view which I had taken was correct, 

 which the discovery of a spring helped to dispel. 



The heading of the Gobinpoor cross fault is 25° west of north. 

 It is probably continued across the Koonar and 

 instrumental in cutting ofi" the rocks west of 

 Khetko. This is by no means clear, however, and so it is indicated by a 

 dotted line only. A diversity of dips is visible in the Koonar north of 

 Buriya, which is suggestive of a fault. 



The village of Gobinpoor consists of three tolehs. Two dykes 

 occur near the middle one, striking a little north of west. 



A good section is seen in the Montiko Nuddee. The first seam of 

 coal is exposed 600 yards south of the boundary.
