134 FOOTE : SOUTH MAHRATTA COUNTRY. 



Great brecciatiou occurs also at the apex of the Wajarmatti curve of 



the upper quartzites and also close to Kaladgi, at the western end of 



the " Cromlech hill " outlier. At most of the curves at the ends of the 



several synclinals the bedding is greatly broken up by jointing, e. g., at 



Govindakop, at the north-west end of the Shimageri basin, at the east 



end of the Lokapur basin, at the western end of Anathilli basin, at the 



Baulatti (?) (Bowluttee) curve, at the east end of the Arrakeri valley, at 



the northern end of the sigmoid curve, north of Wajarmatti, and at 



the western end of the Yenktapur basin (the most westerly exposure of 



the tipper quartzites). This great comminution of the bed surfaces is 



due mainly to the presence of rude cleavage joints caused by great 



pressure when the rocks were forced into the folds they are now seen to 



form. At the northern end of the Wajarmatti sigmoid these cleavage 



joints occupy a position distinctly radial from 

 Hadial cleavage. 



the western focus of the imperfect ellipse formed 



by the quartzite ridge. The surface of many of the curved beds is so 



greatly obscured by detritus that it is almost impossible to trace the 



actual curving of the lines of deposition ; the comminution of the rock 



has gone to such an extent that it is generally very hard to find a mass 



of stone sufficiently large to be certain of its being in situ. The western 



end of the Jembigi ridge curves on itself and forms an imperfect basin 



which is entirely covered in by the Deccan trap. 



The northern arm of the Arrakeri synclinal extends in a broken ridge 



forming numerous inliers in the Deccan trap area

for twenty-seven miles, nearly all across the 



northern part of the Mudhol State. The inliers mostly form narrow 

 ridges 50 to 60 feet highj consisting of whitish or pale -reddish quart- 

 zite with pebble beds. One of the reddish beds occurring at Maha- 

 lingpur (Malingapoor) is very strongly rippled. The dip of the ridge 

 declines steadily westward from 70° south, where it is crossed by the 

 Sholapur-Bijapur road to 50° — 60° at Arrakeri village, and 35° in the 

 rippled bed on which the Mahalingpur fort is built.
