121 POOTE : SOUTH MAHRATTA COUNTRY, 



The limestone exposures north of the Ghatprabha and westward of 

 Kaladgi now demand attention. The furthest 

 the'^KAtTarGaTg'ir ^om KaMdgi lies on the bank of the Krishna a 

 little east of Galgali (GulguUeh) . There and in 

 the bed of the river north of Yedhalli (Yedulleh), and visible only when 

 the stream is low^ are two beds of limestone, the upper dark-grey, the 

 lower light-grey in color. The upper is very silicious, with the eherty 

 concretions arranged vertically like so many rude organ pipes and not in 

 layers. The lower bed is remarkable, because the surface, wherever exposed, 

 is "cockled" up into large^ flat, elliptical domes 4 to 6 feet long by 3 or 4 

 wide — an arrangement suggesting a pavement made by placing close 

 together the carapaces of hundreds of huge turtle. This bed re-appears 

 «T ti h k" t north of the Krishna at Jembigi (Jumbgeh), and 



ture. presents the same "turtle-back" undulations. In a 



nullah falling into the Krishna, a Httle south-west of Jembigi, the "turtle- 

 back" bed is seen to rest on another massive limestone which includes frag- 

 ments of quartzite. Only a few square feet of this latter bed are exposed. 

 A great show of extremely eherty dark-grey limestone is to be seen in the 

 bank of the Krishna just south of the village. This extends across 

 the river to Budihal (Boodehal). At Gulabal (Goolabal), a mile to the 

 south-west, the chert limestone has lost nearly all its calcareous matter, 

 which has been replaced apparently by a pale-yellow ochrey mineral, and 

 the bed assumes in parts the appearance of a dirty -looking semi-cherty 

 quartzite. North of Galgali in the bed of the 

 river, and resting upon the quartzite beds which 

 here form the great barrier across the Krishna, are some thin beds of 

 impure limestone with intercalated thin bands of chert quartzite (very 

 thin) and the ochrey mineral above mentioned. Some laminse of white 

 satin spar with very brilliant fracture also occur. The ochrey bands, 

 which are dirty red, yellow and drab in color, and certain white, chalky 

 laminse which accompany them, are most likely merely decomposed 

 shaley beds. A bed of grey quartzite caps this peculiar succession of beds.
