224 WYNNE : GEOLOGY OF KUTCII. [pART II. 



Northward of this village there is some local disturbance of the rockSj 

 and ft black muddy band, dipping sharply to the south-west, contains 

 Ammonites, Belemniies, a large CucuUcea, a small Ostrea, MhyncJionella 

 mynacantlia, and fossil wood. Horizontal black shales and sandstone 

 at the village and near it 'are capped by hills of the intrusive trap, some- 

 times supporting small outliers of white altered sandstone, and on the 

 road to Joonacha, a large Trigonia, like T. Smeeii, occurs in weathered sand- 

 stone beds overlying black shales. The intrusive trap occurs in force 

 in this neighbourhood^ and the black shales- with Ammonites, ^c, were 

 not observed anywhere else in the whole province. 



Near the last named village gigantic ripple marks on the surface 



of some close brownish sandstones, lying nearly

horizontal, were at first sight taken for the drills 



of a field ; they measured 4 feet from ridge to ridge, and exceeded in 



size anything of the kind seen elsewhere in Kutch.* 



Southward of fhis place is a broad sandy plain, in which hori- 

 Plains near the Goti zontal rocks of upper Jurassic aspect are occa- 

 "* ° ■ sionally seen, extending to a north and south chain 



of hills, which connects the trap escarpment near Malka with the fine 

 hills of Gandara. This chain also exposes the white upper rocks, and 

 another great plain covered by sand and broken by a few isolated 

 sandstone hills extends westward to the margin of the stratified traps 

 near Rora and Asooree. 



Near what may bV spoken of as the north-western termination 



of the great central plain, the hamlet of Oomia

lies between the sandstone spurs from Gdndara 



and the intrusive trap hills to the north. A solitary peaked crag of 



dark-brown massive silicious grit marks the site of the village, present-

 east bastion of the city wall of Bhooj, in red sandstone beds.
