kalIdgi series. 71 



inliers, partly outliers, as they both overlie small patches of gneiss and 

 are themselves overlaid by the Deecan trap on three sides. To the 

 south-east of the Kaladgi basin are the Gudur and Hanamsagar out- 

 liers and a group of outliers between Belur and Gajendragarh. Finally ^ 

 to the south of the basin are the outliers capping two hills of Nargund 

 and Chik Nargund, and that capping the Parasgarh hill and two small 

 ones to the north-east of it. 



By far the most important sections are, however, found within 

 the boundaries of the Kaladgi basin itself, which will therefore be most 

 fully described. 



Taking the series as a whole, it is decidedly metamorphic where 

 disturbed. The disturbed parts are those lying within the basin ; the 

 undisturbed with a few exceptions are the outliers at the eastern and 

 western ends of the basin. Not the faintest trace of any organism 

 rewarded much earnest and close search, and as previous explorers had 

 been equally unsuccessful, the Kaladgi series may for the present be 

 regarded as azoic. 



The whole series may, after careful examination, be sub-divided as 

 follows in descending order : —

6. Shales, limestones, and hsematite schists ... 2,000, ? 



5. Quartzites, with local conglomerates and breccias 1,200, 1,800,

3. Sandstones and shales ... ,,. ... ^ 



2. Silicious limestones, hornstone or cherty breccias ^ 3,000, 5,000,

The aggregate thickness of the whole series has not been satisfac- 

 torily determined, as no sections were found in

which both top and bottom of the two limestone 

 and shale series were exposed ; only imperfect estimates of their thickness 

 were possible ; but even these show that the series is of very great thick-
