14-8 WYNNE : GEOLOGY OF KUTCH. [PART II. 



? 7. — Yellow sandstone with annelid tracks, purple and yellow sand-"^ 

 stones witli raggy clay partings and containing close grained 

 fragments of fossil timber, beds ripple-marked in places 

 (lu a nullali from Eoba hill, which enters the main stream here, occurs 

 about 50 feet of horizontal sub-recent calcareous sandy concrete) 



8. — Soft white sandstone with ferruginous nodules and large quart- 

 zose masses, being with the last mentioned beds the represent- 

 atives of the sandstones capping Roha hill ... ...J 



9. — Thin-bedded pale yellowish variegated shale, white and purple, 



thin purple sandy bands ... ... ... 150 „ 



10.— Soft, thick banded, blood-red, yellow and white obliquely") 



laminated sandstone with soft red ferruginous bands ... > 100 



11. — Ferruginous rugged band ... ... ... ,.,J 



12. — White sandstone ... ... ... ... 20 „ 



13.— Rapid alternations of platy, red, ripple-marked, and soft white 



sandstone with two narrow purple zones ... ... 100 „ 



14. — Purple sandstones occasionally micaceous ... ..."^ 



15. — Ferruginous beds very rugged and red alternating upwards I 



with light coloured flaggy and shaly beds, dip to south be- T " 



comes as low as 5° to 10° ... ... ... J 



16. — White rugged sandstone, some red, sandy, and shaly bands and 



occasional beds of conglomerate in the upper part . . . 200, &c. 



Near the place where this section terminates is the semicircular 

 group of rugged serrated conical and flat topped 



Hurrulbet hiU, &c. 



hills before mentioned^ one of the most conspicu- 

 ous of which called Hurrulbet hill is formed of a mass of white and 

 purple horizontally undulatiug soft and hard irregular blotchy sandstone. 

 A trap dyke^ from 9 to 15 yards wide, passes its foot on the east side 

 with a south-westerly strike, and all the other hills in the neighborhood 

 belonging to this group have intrusions of the sam3 dark gray or basaltic 

 trap passing through them and forming their summits. On the most 

 westerly hill the trap forms a heavy capping of considerable thickness, 

 and although not distinctly stratified may be an extension of that which 

 overlies the beds of the Buchao and Lettera range. 



The remainder of the ground in the vicinity of these hills is occu- 

 pied by coarse, white, and black ferruginous sandstones, with red and 

 purplish quartzose bands, the whole having the ordinary superior 

 Jurassic aspect.
