DECCAN TRAP IRON-CLAY. 221 



tained decreases steadily with tlie depth. The rock is also very distinctly 

 bedded. Below the base of the scarp no rock is satisfactorily seen in sitti ; 

 but the sides of the hill are covered with iron-clay debris, or masses doubt- 

 fully in place. Nor is the gneiss exposed for some distance from the base 

 of the hillj and the nearest visible portion of Deccan trap is the south spur 

 of Yellurgarh hill^ fully three and a half miles to the north-west. 

 From its external resemblance and its level, as compared with Yellurgarh, 

 it is not unlikely that it represents an altered inter-trappean or infra- 

 trappean deposit. 



Beyond the limits of the trap area in Kaladghi district are two 

 o tr f th ■ - outliers of iron-clay which certainly bear a very 

 ^'^^y* striking resemblance to typical exposures of it, 



and the probability of their being connected with the trappean series is 

 rendered more probable by the occurrence of two small patches of iron- 

 clay of identical appearance to one of the two first-named, and resting 

 on the Deccan trap. The two first-named outliers occur, the one near 

 Bellegunti, three miles south-west of Kerur (Kehroor) in Badami Taluq, 

 while the other forms a very conspicuous truncated cone capping a 

 quartzite plateau five miles south-east of Kerur. The two outliers resting 

 on trap occur a mile south-east of Batkurki. In the case of the Hulikeri 

 (Hoolikeree) hill south-east of Kerur, the iron-clay is a very distinctly 

 vertically tubulated variety, but both the Bellegunti and Batkurki 

 patches consist of vesicular and vei'micularly tubulated iron-clay.
