intermediate g^roups (Raaigaoj and Panchet). They have in conjunction 



with the great north-west south-east fault facilitated the upheaval of the 



wedge-shaped areas of metamorphic rocics which give to the field, as 



mapped, an appearance which, at first sight, might be thought to be 



due to a huge fling and distortion of the field by the agency of the north- 



west south-east fault alone. Owing to the fact that where the more 



southern, east and west fault intercepts the north-west south-east one, and 



similarly where the more northern of the pair intercepts theLatiahar and 



Putkee fault, no lateral displacement in either case is discernible, the 



Eelative ages. question of relative ages becomes one of some 



difliciilty. The balance of probability, however, 



seems in favor of the north-west to south-east fracture having taken place 



first, and that the rocks were simply vertically upheaved in the angles when 



the east and west faulting took place. The other east- west fault of the 



Aurunga field is that which forms a portion of the northern boundary 



where it cuts off several patches of Barakars and is connected with the 



hot spring at Jarum. 



In the Hutar field one east and west fault has cut off the Barakars at 

 Hutar field faults. ^orwaie, from whence westwards up to the Koel 



its course is indicated by fault rock and the hot 

 spring at Thatha. West of the Koel its existence is somewhat doubtful, 

 but its line of strike coincides with the base of the scarp of the Doothoo 

 hills, and its existence there would help to account for a diminished 

 thickness of the Barakars south, as compared with those north of the hills. 

 The other east and west fault of this field is well marked near Binda 

 where it has cut off the small patch of Talchirs and Barakars. Appa- 

 rently it is older than the neighbouring fault of the north of west to 

 south of east system. 



2. North of east to south of west systeyn. 

 The first example of this system to be mentioned is the one which 

 has flung the limestones described in section 1 of this chapter. Its course 

 from Pukree to Korean strikes 15° north of east to W south of west.
