10 GEOLOGY 



ferruginous bauds, aud a little further soutlij at Badj'e, limestones 

 appear containing' fossils, chiefly Pedens and other bivalves. No num- 

 mulites were met with. 



Here alluvium comes in. Indeed, no continuous section Avas seen 

 except close to the trap. 



4. — Discussion of results. Jurassic heels. — It will be noticed 

 that the general dip of the beds throughout the portion of Cutch 

 traversed is, as has already been observed, to the south. There is 

 much local disturbance, but no indication, so far as was seen, of any 

 great faulting. Still such may occur, and may so seriously complicate 

 the beds as to render all conclusions as to their relations uncertain. 

 But the dips are, in general, so steady, and there are such large tracts 

 of the country free from any important disturbance, that I believe 

 perfectly sound deductions may be made from the observations above 

 detailed, and that no great error will be incurred by viewing the whole 

 north and south section of the rocks exposed from the broken anti- 

 clinal on the banks of the Runn to the alluvium near Mandavee as a 

 simple ascending series of beds. It is particularly worthy of notice that 

 no great and sudden change of mineral character takes place anywhere 

 north of the trap boundary, such as might be expected in a break of 

 sequence between marine and fresh water beds. 



The lowest beds seen in Cutch appear to be the marine fossiliferous 



beds of Jooria and Charee.* South of Jooria these distinctly pass beneath 



the white and brown sandstones of Bakria and Dhosna, the Charee 



rocks pass upwards equally clearly into the plant-bearing series of Jogee- 



Arul, and the fossiliferous marine formations of the Katrore hill and 



Charwar range dip steadily beneath the Zamia beds to the south. So

* The beds of- the islands in the Rutin, the Putchum, and Kureer, shown in Captain 

 Grant's sections to dip to the south, may be lower than the Jooria beds, but they are well 

 known to be marine, and are represented as such in Captain Grant's map. I had not time 

 to visit them.
