258 WYNNE: GEOLOGY OF KUTCH. [l-ART 11. 



This might have been supposed to result from unconformity, if the 

 nummulitic beds were found to be derived from the underlying rocks ; 

 but this is not the case, and the succession which they exhibit in other 

 places indicates rather that the absent beds have thinned out in this 

 neighbourhood. 



Very similar lateritic gi-ound extends from this to the neighbour- 

 hood of Samdiwari, where a sheet of laterite from

10 to 20 feet thick occupies a slight synclinal 



depression of the traps and supports several small outliers of the tertiary 

 rocks. 



These outliers also exhibit the variable character of the rocks, some 

 being composed of compact, pinkish-yellow, limestone overlying 20 or 30 

 feet of soft, yellow, and pale-blue shales, while in others the limestone 

 rests directly on the laterite. As this limestone contains organisms 

 characteristic of the uppermost nummulitic beds, it would appear that 

 the deposition of the greater portion of this group did not extend to 

 this locality. 



To the south of this beyond the southerly slope of the trap, the 



small but very conspicuous conical hill of Hekelu 

 Hekelu hill. 



rises to a height of over 150 feet. Much of the 



intervening space is occupied by the lateritic group, which is, however, 

 greatly concealed by superficial deposits, and close to the base of the hill 

 are ferruginous and variegated soft thick-bedded sandstones, crossed by 

 several lines of fracture accompanied by much disturbance. Fallen 

 masses from the hill obscure its lower portion, the upper part being com- 

 posed of strong finely compact grits which weather like limestone and 

 have a blue colom- internally. These rocks are not traceable in the 

 vicinity, though from their nearly horizontal position and the height of 

 the hill they must have a considerable thickness. It is therefore pre- 

 sumed that they have been brought into their present position by the 

 occurrence of faults, which is rendered more probable by the complex
