west of the latter village a strong trap dyke, varying in width up to 

 160 feet, extends northwards to the crest of the range. 



Between the gh^t on the above road and the village of Mankooa, , 



Complication near the ^° *^^ P^^^^ *° ^^^ north-west, the great Charwar 

 Mandavee road ghat. ^nd Katrol fault becomes checked, displaced, and 



complicated by the occurrence of numerous minor fractures, the effect 

 of which has been to remove its general bearing about a mile further 

 to the south, the lower rocks in this vicinity being greatly disturbed, 

 contorted, and traversed by trap dykes and intrusions of varying tex- 

 tures and hardness. The largest of these occurs in the main line of 

 fault and the lower beds in contact are intensely altered. 



For some distance on each side of the Mandavee road along the 

 northern base of the Charwar Hills, the fossili- 



Disturbance near the 



ghat on the Mandavee ferous beds of the lower series occur among the 

 contortions just south of the fault. They con- 

 tain numerous Terebratulce, Ammonites, (StephanocerasJ tumidum ? more 

 rarely, Ostrea (undeterminable), Belemnites (undeterminable), Cucullea 

 virgata, Trigonim, Pleiirotomaria, and others, chiefly bivalves. 



South of Samtra the hills recede in that direction and a broad 

 Becess in the hills space is occupied by broken ground with some 

 south of Samtra. ^^^^ ravines. The lower beds are still muck con- 



torted along the south side of the fault, which is clearly traceable, 

 running nearly east and west, while those of the upper group on its 

 northern side undulate at low angles. A strong dyke of light brown 

 porphyritic trap, running from the hills northwards, shows several dis- 

 locations along its course, and the various alterations of shale and sand- 

 stones in the country on each side of it are the same as usual in the 

 lower portion of the Jurassic series. 



Succeeding to these, hard, gray calcareous grits dipping to the 

 southward form a craggy ridge through which this dyke could not be
