associated with igneous intrusions or lines of fault or fissure through

Within the positions occupied by the lateritic series, the Jurassic 



rocks undulate with many irregularities and occa-

sionally high dips over the country, rarely rising 



into high hills, dipping round their exposure generally outwards, and 



presenting in almost every view long lines of outcrop gradually dying 



out; their prominence giving place to that of others, or suddenly ending 



in small abrupt cliffs. An anticlinal axis, or more than one, passes in 



an east and west direction near Adhove, Chitrore, and Kaumeer, but the 



contortions being complicated by curvature of their axes, interruptions 



in their strike, and local occurrence of minor curves, the anticlinal 



becomes too confused to form a strongly marked feature of the ground. 



All over this Wagur portion of the district the Jurassic rocks present 

 a complex aspect, in places resembling the lower beds, in others the coarse 

 upper ones, while in many localities, beds, most like those occupying an 

 intermediate position, have intercalated bands containing marine fossils. 



There being no definite arrangement traceable which would place 

 these beds in an ascending series corresponding to that elsewhere seen, 

 they have been supposed to change laterally, so as to present in their 

 vertical order a wider transition from the lower to the upper characteris- 

 tics, and one more than usually marked by the presence of marine 

 fossiliferous beds. In some localities, however, there is a prevalence of 

 the coarse white sandstones typical of the upper group in which, 

 notwithstanding close search, none of the Palmozamice or other plants 

 have been discovered, nor any marine forms either. In the absence of 

 fossil evidence, these have on petrological grounds been included in and 

 mapped as belonging to the upper sub-division. 



At the north-west side of the tract the ground has no great eleva- 

 tion, its surface showing long level lines broken only by an abrupt hill
