60 POOTE : SOUTH MAHRATTA COUNTRY. 



A fourth group includes a number of dykes whose course is 



north-west-by-north. The two principal members 



4tli Group : _ "^ r i 



N. w. by N. to S. E. of this group are a large dyke which runs through 

 the village of Bhagalwada^ west of Bhanur (Bhun- 

 noor) in the Raichur Taluq^ and another large dyke which disappears 

 under the Kaladgi basin at Eamapur, and apparently re-appears from 

 below the Kaladgi rocks at Chimalga (Cheemulga), on the north bank 

 of the Krishna. 



^fftli group may be established of dykes having a north-east 

 5th Group : ^^ south-wcst course. A numerous set of these 



■ * cross the remarkable inlier of gneiss in the Kath- 



arigarh hills in Belgaum district. Dykes pursuing this course are not 

 numerous in the main gneissie area. There the largest and most impor- 

 tant of this group is a very broad dyke^ rising from under the regur 

 three miles west-north-west of Beiir (Behwoor), and running for about 

 eight miles, till it joins another very large dyke with an east-by-soutb 

 to west-by-north course, on the north side of tvhicb it does not re-appear 

 or is lost immediately under the alluvium of the Krishna close to the 

 village of Mudukop (Moodookop). 



There remains lastly to be noted a very remarkable set of dykes of 

 great size and length, different parts of the course 

 of which might be reckoned to belong to different 

 groups. The main dyke is first seen at Togulugallu, a couple of miles 

 south of Baman-Kallur, on the Raichur — Ling Sugur road. It forms a 

 higli rocky ridge, the Arrankerri hill of the map (north-west \ sheet 58) 

 six miles east-by-sDuth of Mudgalj and continues as a great north-east 

 south-west dyke, rising at various places into rocky ridges, till about a 

 mile west of the Ling Sugur — Bellary road, when it disappears suddenly, 

 A branch of it given-off to the east of the road continues the same course 

 for a while, and crosses the great Hunugunda schistose gneiss band about 

 four miles north-east of Tawurugiri. It here rapidly trends in its course 

 to the westward, and is joined by another large dyke about 600 yards 

 ( 60 ) 



Jumalapur dyke group.
