The isolation of this trap outlier has an important bearing upon 

 the geology of the district. If it were caused by denudation previous 

 to the deposition of the sub-nummulitie group, the latter must be every- 

 where unconformable to the underlying traps. This^ however^ is not 

 borne out either by observations in detail or the general persistence 

 with which that band occui-s, always in such positions as to overlie the 

 newest of the trappean flows. 



An unconformity marking such an interval of time as would be 

 required to remove by denudation oome 200 feet or more of these traps 

 from the country between Dharisieu and Lickka hills, might have been 

 expected to leave many inequalities in the trap surface where this 

 band of sub-uummulitic beds, often not moie than a few feet in depth, 

 would be completely concealed by the ov:rly!u-j- lower tertiary deposits. 

 On the other hand, it is plain that the trappean flows or beds of these 

 locaKties once extended further towards each other than they do at 

 present, and that so far denudation has removed them. The junction 

 of these traps with the overlying group takes place in low ground, 

 where the relations are much obscured and thinning out of the traps is 

 difficult to determine, but notwithstanding this, it 's probable from the 

 general relations of the stratified trap to the succeeding group, that the 

 Lickka hills outlier either existed originally as a separate accumulation 

 or that such an inequality of the old Jurassic surface existed as prevented 

 the flows of this outlier from joining those to the south. 



From the occurrence of the stratified traps again at Bheti hill to 

 the west, it is probable that the Lickka flows extend in that direction 

 beneath the newer rocks.

general aspect is that of the upper or transition portion of the group,
