LOWER TRANSITION ROCKS. Ill 



Rather more than two miles north-west of the Nandgarh gate in 

 the Bhimagandi gorge, the great haematite beds 

 which there have a north-west to south-east 

 strike make a very marked and conspicuous bend to the west, and the 

 apex of the outcrop on the south side of the curve is crowned by a 

 small ruined hill fort known as Timappangarh (Timangur). The fort 

 stands on a great bluff, squarish in outline, which juts out from the 

 general scarp of the Ramgol ridge. The rock is beautifully banded 

 and highly jaspideous in texture, and shows in parts a beautifully 

 vandyked contortion on a small scale. The colours of the rock are 

 also very good, the laminae of quartzite being white, rich cream, pink 

 in many shades, and red, up almost to a pure vermilion tint, while 

 the haematite laminae vary from reddish grey up to pure steel grey, 

 sparkling with minute crystalline facets of specular iron. The 

 exposed side surfaces of the haematitic laminae frequently weather of a 

 rich purple. The weather-resisting power of the haematite quartzite is 

 very well seen on the bassett edge of the Timappangarh ridge in the 

 hardness of the outcrop and its commonly glossy jaspideous surface, 

 which is rarely covered by lichens except in very exposed and greatly 

 weather-beaten crags or ledges. 



The amphitheatre formed by the curve of the strata below the 

 Drug scarp is thickly covered by fallen masses, of all sizes, of the Drug 

 haematite bed, which lie in such thousands all over the surface that the 

 trapflow, which should really show there, is completely hidden. The 

 number of exquisite specimens of jaspideous rock here seen is so great 

 that it is difficult not to wander for hours among them. The beauty 

 of the jasper rock and its fitness for art uses will be referred to again 

 in the chapter on Economic Geology. 



The most prominent object in the central part of the North 



Inversion of beds on Sandur Valle 7 is the g reat hil1 J uttIn g 0ut 



Hunshahuti hill. south-westward from the Ramgol ridge q\ miles 



north-w r est by north of Sandur town and which may be con- 

 veniently called the Hunshahuti spur. The structure of it is not very 

 easy to understand, for the broadening out into a little plateau of the
