GNEISSIC ROCKS. 53 



The relations of the Amiug-arh and Hunugunda hsematite beds were 

 not determinable owing to the great spread of cotton soil lying between 

 the two. They differ somewhat in character^ the latter^ excepting- 

 at the Yerkal cliffs being more schistose and less jaspideous in texture, 

 and being much less stained with the red color so conspicuous in the 

 Amingarh beds. Two inliers of the latter rise within the limits of the 

 Kaladgi basin, — one a few hundred yards from the Amingarh hill, the 

 other several miles to the westward near Kamatgi (Kummutgee) on the 

 left bank of the Ghatprabha. 



Numerous beds of hsematite-schist are met with in the upper valley 

 of the Malprabha in the Bail Hongal (Byl Hongal)

schistose band. They differ m no essential re- 

 spect from those above described, and except that they form conspicuous 

 ridges among the softer schistose rocks there prevalent, they merit no 

 special . mention. As a rule, they are poor in iron, and but rarely show 

 much of the red staining, though frequently jaspideous in texture. The 

 country is covered with their debris to a remarkable extent. Minute 

 quantities of gold are found in some of the nullahs in the Bail Hongal and 

 Belowaddi townships, but they are so small that the sands are hardly 

 washed now-a-days. No gold is known to accompany the numerous 

 hsematitic beds in the Kaladgi district and western part of the Raichoor 

 Doab. A moderate-sized hsematite-schist bed forms a well-marked 

 buttress on the south-east side of the Chik Nargund hill in Dharwar 

 District. The bed, which is very rich and of dark purple color, dips 

 east-by-north at a high angle ; it belongs to the same series as those 

 forming the lower portion of Pedda Nargund hills. 



These hsematite-schists are but very slightly if at all represented 

 in the Konkan gneiss area, where their place seems to be occupied by 

 quartzites and altered ferruginous sandstones which are of frequent 

 occurrence, but do not form very conspicuous and important bands as 

 they do in the Deccan.
