192 WYNNE : GEOLOGY OF KDTCH. [PART II. 



To the westward of Rampur, a long nortli-westerly dyke forms a 

 chain of hills called by the natives ' Saat 3£ouri,' 



Saat Mouri Hills. 



from having seven conspicuous summits. The 

 strike of this dyke is somewhat irregular, and its width varies up to 

 25 feet or more. Between some of the hills the trap disappears, and a 

 reef only is found similar to the runs of quartzose rock so frequently 

 seen in the Jurassic ground. The trap of this dyke is compact, dark- 

 grey and augitic, in some places columnar, the columns being trans- 

 verse to its direction and horizontal. Its termination near Rampur 

 bending to the southward is plainly visible, standing out from the 

 amygdaloidal trap flow which it there crosses. 



Westward of this dyke, upper Jurassic beds of the usual kinds

coloured sandstones, with some thick shales, were 

 taken to represent the transition portion of the lower group. Here some 

 large intrusions of compact and crystalline trap, partly in the strike 

 of the Saat Mouri dyke, cross the disturbed beds, obliquely rising 

 upon some low hills, and in places include or are capped by whitish 

 indurated sandstone. 



In the country lying between Nambye, Koorbya, and Deysurpur, a 

 strong group of hills rises to the west of the recess

in the Charwar range south of Samtra. They 

 were spoken of as the ' Gorkur Hills^ ; but as it was uncertain that this 

 name was generally known, it has not been introduced upon the map. 

 These hills form a most complicated piece of ground, traversed by innu- 

 merable trap dykes and intrusions between the beds. The latter, consist- 

 ing of alternations of shale bands and hard massive, white and grey, 

 silicious grits, undulate much, but have a general dip to the south-west 

 aad west-south-west.
