CHAPTER III. 



GNEISSIC ROCKS. 



The gneissic or older metamorphic rocks which occur in the South 

 Mahratta Country^ occupy^ as a glance at the accompanying map will 

 shew, mainly the western_, southern and eastern portions of our area. 

 Whether they all belong to the same age, geologically speaking, or 

 whether future and more exhaustive examination of them will lead 

 to their being sub-divided into groups of different ages, cannot be at 

 present decided, nor need the subject be further entered upon here, 

 although it is extremely probable that they will admit of being sub- 

 divided and classified. 



There are several noteworthy inliers of these ancient rocks, exposed 



by denudation of the younger and overlying forma-

tions. Among these are, though small in size, 

 two hsematite- schist inliers west of Amingarh and Kamatgi, on the 

 right and left banks of the Ghatprabha river, between longitudes east 

 75° 40' and 76°. These protrude througb the Kaladgi series, the oldest 

 post- gneissic rocks of this region. Besides there are the Katharigarh 

 (Kuttargurh) inlier, thirty miles east of Belgaum, and the Halki and 

 Budnur (Boodnoor) inlier north of the Belgaum-Kaladgi road. West 

 of these are the Wunnoor and Pachapur (Padshapur) inliers. 



To the north of these are other three inliers, which may be dis- 

 tinguished as the Kelvi, Mamdapur and Gokak inliers. 



Further to the south-west are two inliers in the valley of the 

 Belgaum nallah. Westward of Belgaum and close to the village of 

 Patna are two small inliers showing through the Decean trap. 



Two small inliers of granitoid gneiss appear protruding among the 

 sandstones and quartzites of the Kaladgi series at foot of the Phonda 

 Ghat.
