TRAP?EAN SERIES. :il 



far off. On the whole^ the rocks of the western portion of the Bazargaon 

 inlier much resemble some of those seen at Sdlbaldi east of Ellichpur. 



The rocks near Larai about the centre of the sandstone patch are 

 exactly similar to those seen further westj but 

 instead of being horizontal, they dip to the south- 

 west. From beneath them, south of Lonhara, grits and red and yellow 

 compact shales crop out, similar to those of Silewada and Kamthi. 

 These grits are not conglomeritic ; they contain the usual hard fer- 

 ruginous bands, fragments of which are scattered over the country. 



To the south near Dhamna scarcely any sandstone can. be seen in 



place, but north of the village plenty is visible.

The trap is well exposed outside the north-east 



boundary near the village of Ashti, but thence towards Lonhara all the 



rocks are concealed by alluvium, and it is impossible to say what are the 



limits of the sedimentary formations in this direction. They may extend 



towards Kalmeswar, but it is more probable that trap exists beneath the 



alluvium in that direction.

 a. Infratrappean or Lameta Group. — Throughout the greater 



portion of the trap boundary between Nagpur and 

 At Kelod. 



Kelod, wherever the contact of the two series is 



exposed, the igneous rocks rest immediately upon the sandstones of the 



Kamthi group. At Kelod a thin infratrappean bed is met with. It is 



well seen about half a mile west of the town, resting upon Kamthi 



sandstones, and again to the north near Jaithgarh tank, where it overlies 



metamorphic rocks. The bed in each place is nodular calcareous grit 



or gritty limestone, and the thickness apparently does not exceed 10 



feet, but perhaps it is more than this, and it probably varies. Down 



the stream which flows past Kelod, about 200 yards east of the small 



quarry, itself at the east end of the town, the Kamthi rocks are seen
