BHTMA SERIES. 141 



A precisely similar purple gritty bed occurs at Bulehwar^ five miles 

 Qorth-west of Jambaldinni; this probably occupies the same horizon 

 in the Karnul series as the Jambaldinni bed. But five miles to the 

 south-south-west of Jambaldinni at Kaurimatti (Kowreemuttee) a simi- 

 lar purple gritty sandstone forms the base of the Karnul series. 



About two and a half miles south-east of Jambaldinni a bed of purple 



gritty sandstone (almost a quartzite in texture where not excessively 



weathered) caps a table-topped hill with a well-defined scarp (not laid 



down in the map). This is probably the same bed as the Jambaldinni 



millstones are quarried from. The south side of this small table-land is 



well scarped, and shows a total thickness of about 

 Jukrihal hill section.

3. Purple, gritty sandstone (quartzite). 

 2. Drab, olive and purple and dark-green shaley sandstones. 

 1. White or drab pebbly grit. 

 Gneiss. 



The shaley sandstones form more than half the thickness of the 

 whole section. Much pisolitic laterite gravel occurs, strewn over the 

 surface of the purple sandstone. 



A purple gritty bed, occurring near the base of the series, is quar- 

 ried at Bassarkot (Bussurkee), five miles north-west of Muddebihal. 

 This bed is quarried for millstones. 



The basement beds of the Bhima series in the western part of the 

 1 >, . f f ^1'®^ consist almost everywhere of pebbly or 

 basement beds. gritty sandstones of moderate thickness rarely 



exceeding from 30 to 50 feet, and resting directly on the highly uneven 

 surface of the gneiss, which in many places stand up in great hummocks, 

 surrounded by the younger deposits. These may in several places be 

 seen protruding far above the base of the younger series, e. g., 

 at Salwargi and Matkaldevunuhal on the Talikot-Sorapur road, where, 

 as shown in Section III, plate IX, the granite gneiss rises in three or
