LOWER TRANSITION ROCKS. 109 



The conglomerates are in all probability representative of the 

 Ramgol and Joga stream conglomerates. A singular and interesting 

 travertine formation resting on the dark micaceous argillite (No. i) 

 at foot of the gorge will be found described further on. The " Water- 

 slide " would be a good name for the place in the absence of any- 

 known one. The low ridge of conglomerates which the stream 

 breaks through just above the "Water slide " rises rapidly to 

 the westward and forms the main easterly spur of the Jambonath 

 Konda. 



The angle of dip of the conglomerates at the gorge is very high, 

 but they show no sign of deformation ; but as the ridge is followed the 

 dip increases somewhat, and the numerous pebbles included in the 

 conglomerate become greatly squeezed and elongated in the direction 

 of the strike of the beds. This distortion is found to increase till 

 abreast Jambonath Konda Trigonometrical station. Here the matrix 

 of the rock is a silky (micaceous) striated quartzite sandstone with 

 numerous siliceous inclusions resembling anything but the rounded 

 pebbles they originally were. They have been squeezed into long 



flattened cigar-like bodies! But that I traced 

 Deformation of peb- 

 bles in the conglo- them, foot by foot, along the outcrop of the conglo- 

 merate bed, I should unhesitatingly refuse to 

 believe the alteration they have undergone. However, the evidence is 

 quite irresistible. The conglomerate band continues westward of 

 Jambonath Konda, but thins out rapidly. It can still be traced at the 

 gully which lies west of Jambonath temple gully, and has here a thick- 

 ness of only 25 feet. Further west it thins out more and more, and 

 disappears before one reaches the little Rampur ghat which is crossed 

 by the Hospet-Sandur road. 



The conglomerates which figure so largely in the Joga and Ramgol 

 The Bhimagandi sections are not seen 4 miles south-eastward 



gorge " in the Bhimagandi gorge. The character of the 



rocks seems to have changed completely, and there is no trace of 

 brecciation in the Ettinahatti haematite beds, which are very fairly rich 

 in iron, and can only be described as very ordinary haematite quartzite. 

 These beds abut on the Bhimagandi gorge by which the Narihalla
