84 FOOTE : SOUTH MAHRATTA COUNTRY. 



"^ The conglomerates are unusually thin here^ and the quartzites pro-' 

 portionately thick. The quartzites are quarried^ and a very remarkahle 

 monolith, a siamb/ia or sacred lamp-post, standing- on the top of Bilgi 

 hill, is said to have been quarried here. This will be referred to again 

 when treating of the economic geology of the South Mahratta country. 



i. Bisnal Section. — The village of Bisnal lies eight miles west- 

 hy-north of Bilgi ; the section was taken about half a mile south of 

 the village in a south-east to north-west direction and shows the follow- 

 ing succession of beds : — 



c. Breccia heels ; bands of earthy (ochrey) impure limestone at 

 base. 

 Quartzites and shaley quartzites of whitish color. 

 Quartzites, red and gritty. 

 a. Grits and conglomerates ; grey, or reddish, of quartz and 

 felspar debris. 

 Granitoid gneiss, red. 



In the corner made by the bend of the hills (due to the trending of 

 the strike of the rocks) about a mile and a half south-by-east of the 

 village are four beds of richly hsematitic schist among the quartzites 

 about the horizon occupied by the upper part of ^'V in the foregoing 

 section. They give rise to four distinct scarps, due to their greater 

 resistance to atmospheric influences. A small quantity of ore was being 

 collected there in 1871, to be smelted at the neighbouring villages of 

 Sidapur (Seedapoor) and Jenmatti (Jehnumtee) . As shown in the map, 

 a line of fault, accompanied by a considerable downthrow on the north 

 side, occurs at the village of Bisnal, the dirty breccia being faulted 

 against underlying conglomerate beds. This fault and downthrow may 

 be traced for several miles to the north-east crossing the Krishna to 

 Jainapur (Jynapoor), and finally disappearing under the Deccan trap 

 about two miles north-east-by-north of the latter village. At Jainapur
