Before passing oiij it may he well to allude to the occurrence of a 



lateritic zone associated also with agatiferous beds 



Relations of this and some white and mottled argillaceous rocks

Surat country compared, at the junction of the tertiary and stratified trap 

 formations in the Sui-at CoUectorate and along 

 the western base of the Rajpipla hills between the Taptee and Nerbudda 

 rivers ; most of the laterites being, like the upper ones of Kutchj in- 

 terstratified in the tertiary [nummnlitie] beds. 



All these Gujrat tertiary beds are considered to be unconformable 

 to the stratified traps of that region.* Evidence of this unconformity is 

 wholly wanting in Kutch, unless the occurrence of the agatiferous laterites 

 or that of trap pebbles in beds believed to represent some of the newest 

 tertiary deposits, here apparently quite unconformable to the rest of that 

 group, be looked upon as a parallel case. 



But the agate-bearing laterites of North-Eastern Kutch are far 

 removed from the stratified traps, resting to their entire exclusion upon
