DECCAN TRAP IRON- CLAY. 215 



The iron-clay beds at Managoli (Mungole) and Mutgi (Miitge) 



in the Bagewari Taluq do not come within the limits of this report and 



were not visited, though they are close to the boundary of the area 



surveyed. Still further east is another outlier of what may be the 



, TVT Deecan iron-clay in the shape of a small capping

^etta. -tQ ^^Q trap at the summit of the Nagurbetta, a 



sharp-pointed conical hill about three and a half miles north-north- 

 west of Nalutwar in the Kaladgi district. The iron-clay is here 

 seen to rest conformably on the Deecan trap, the flows of which are 

 horizontal, or very nearly so. This capping of iron-clay is about 200 

 yards in length and rudely elliptical in plan. It is of deep yellowish 

 brown color and more compact in structure than the ordinary iron-clay in 

 the ghat region, or than the common laterite conglomerate of the Carnatic. 

 The texture also is more porcelanous, and in some parts almost jaspery ; 

 in others, however, quite earthy and dull ; the vermicular cavities so 

 characteristic both of the coast laterite and the typical iron-clay are 

 also absent, but still, when regarded as a whole, there is a decided re- 

 semblance, especially where weathering has taken place. No trace of 

 any organism was found in this rock, but in several places it showed 

 polished striations on different exposed surfaces much resembling those 

 of a " slickenside." Similar markings are occasionally to be seen in 

 very compact varieties of the truly sedimentary laterite in the Carnatic, 

 e. (/., in the south side of the great Sembaram Pakkam (Chumbrum- 

 baucum ) tank in the Madras district. 



Another patch of compact iron-clay lies about a mile south of

territory, some seven miles north-east-by-north 



of Talikot (Sheet 59, S. W., ^). Here numerous blocks of a more 



typical iron-clay conglomerate of the usual deep brownish red color 



occur on the same level with, and mixed up with numerous blocks of 



whitish chert. Owing to the extent of soil covering the knoll on which 



these rocks are seen, it is difficult to decide which rock may be the one
