KALADGI SERIES. 133 



by the outcrop of the qnartzite series ; but the north-western part of 

 this ridge has been omitted in Atlas Sheet 41. 



The southern side of the Arrakeri synclinal valley shows a very clear 

 and well-marked case of inversion of the beds. 

 The beds exposed at the Baulatti ^?) (Bowluttee) 

 curve have a dip of only 25 to 30°^ but almost immediately they have 

 trended round westward they become vertical, and at little more than a 

 mile from the curve they lean forward to the north, so much as to pre- 

 sent the appearance of having a true dip of 85° south. This continues 

 past Kundurgi westward for some distance, when the beds again assume 

 a vertical position and gradually return to a normal northerly dip, but at 

 very high angles, which they maintain for several miles. These highly 

 elevated and inverted beds show a great deal of brecciation. They 

 are also in many parts conglomeratic in character, containing pebbles of 

 quartz, jasper, and occasionally of older quartzite. In one conglomerate 

 bed seen east of the Sholapur-Kaladgi road on the north wall of the 



„ , . synclinal, small sub-angular fragments of trans- 



Green quartz in con- J ^ a o 



glomerate. parent green quartz, very like pale bottle-glass in 



appearance, occur pretty numerously, but only over a very small area. 

 No such quartz was noticed in any of the gneissic rocks of that region. 

 The matrix is a brownish-purple, gritty conglomerate overlying the bed 

 which locally forms the crest of the ridge. 



The most remarkable show of brecciation which occurs in the 



upper quartzites is probably that seen at the great 

 Remarkable breccias. _ 



curve the quartzites of the Jembigi ridge make 



immediately east of the village of Chichguudi in the Mudhol State. 



Much of the breccia has a red, ferruginous, silicious matrix, and forms a 



very beautiful rock. North-east of Antapur the quartzites are also much 



brecciated, and the matrix being very hsematitic, the breccia strongly 



resembles the chocolate breccia so typically displayed in the Lower Kaladgi 



quartzite series near the junction of the Ghatprabha and Krishna.
