Sec. 11.] DETAILED DESCRIPTIONS. 165 



The southern boundaiy of this small patch of cretaceous beds is 

 „ ^, , , extremely interesting-. Near the Kurro the traps 



Southern boundary. ^ o i 



are apparently conformable ; just beneath them are 

 the calcareous bands with oysters, which, west of Chota Oodipoor, are 

 very characteristic of the uppermost cretaceous beds. Despite the g-eneral 

 conformity, however, the dip of the trap appears to be lower than that 

 of the sandstone. 



A little further west, near Chiklee Nanee,* there is some difficulty 

 Sedimentary beds at ^^ determining the boundary between the trappean 

 base of traps. ^^^ t]-jg cretaceous series, the bottom beds of the 



former being- mostly sedimentary ! 



Some of the ash beds above mentioned as occurring north of 

 the cretaceous rocks near Karkunpoor have also a sedimentary appear- 

 ance, and contain fragments of quartz. About Chiklee Nanee, the lowest 

 trappean beds contain, amongst other substances, rolled pieces of trap. 

 The rocks vary much in appearance. Thus, beneath the most southern 

 portion of the village, which is scattered for about a mile along a small 

 valley, a section is exposed in the bank of a little nullah, in which the 

 rock is an ashy conglomerate, composed of alternations of soft, volcanic 

 ash, with harder bands containing sand and small pebbles. These beds, 

 just at this spot, have a sharp dip of about 35° to west-30°-north the 

 cause of which is not evident. 



On the other or western side of the little valley, not 100 yards from 

 this spot, the hill side is formed of sandstones and sandy grits, and 

 especially of a quartzose gritty rock, with red or yellow ochre in the 

 interstices between the grains of quartz sand of which it is composed. 



* Nanee and Motee (or Nana and Mota) are applied to names of ^'illages in districts 

 wbere Gujrati is spoken, just as Chota and Bara are applied in Hindustan, and mean little 

 and big respectively.
