ARCHAEAN AND PLUTONIC ROCK. 41 



A great show of granitoid rock occurs on each side of the valley 

 The Kudligi line of °* ^ je Hampapatna nullah, in the hills rising 

 hllIs - west of the valley from the northern end of the 



Kudligi line of hills (see p. 5). The extreme north end of the line 

 is formed by the elliptical, steep-sided, whale-back hill occurring at 

 Pinjar Heggadahall, two miles west-south-west of Hampapatna. It 

 consists of a highly felspatho-micaceous, granite gneiss with the band- 

 ing much contorted. 



The general character of the granitoid seems to be continuous 

 throughout the Kudligi line of hills ; they present similar bold features, 

 and many of them boast of fine conspicuous tors. The scenery they 

 make is very pleasing. By no means all the hills are shown in sheet 

 59, some of considerable size having been omitted. 



The rock forming the high downs between Hanashi and Timla- 

 Rocks around Kud- P ur > 5 2 miles west of Kudligi, is a felspatho- 

 ''S 1 - quartzose, granite gneiss with both mica and 



hornblende in combination. It is traversed by many, and sometimes 

 large, veins of pegmatite. The dip of the rock is north-eastward, 

 and at the low angle of 20 . 



The banded granitoid forming Shiddan gudda, the conspicuous 

 temple-crowned hill south-west of Kudligi town, is much contorted, 

 and also much cut up by large and small veins of pegmatite. 



To the east of Kudligi, at a distance of five miles, the road crosses 



a thin band of magnetic iron, w r hose north-east- 

 Magnetic iron bed. 



ern continuation joins the magnetic iron bed 



which cuts across the Kudligi-Sandur road four miles north-east of 



Kudligi. The bed is rather poor in magnetite, which is included, 



as it were, in the quartzo-hornblendic laminae of the rock. It is 



an inlier of gneissic character in the granitoid area. 



Four miles south of Kudligi rises the boldly picturesque Viran 



durga (Veeran Doorga), consisting of highly porphyritic, micaceous 



granite, with inclusions of hornblendic rock.

The rock is coarsely banded in parts. The old 

 durga is quite impregnable from any side but the north, where the
