referred to. In the Gaddankeri (Guddengerree) nullah to the south of 

 Shimageri village, grey and drab calcareous shales are seen, which 

 extend southward up to the quartzites on which they rest. These shales 

 are much but very irregularly cleaved parallel to the strike of the syncU- 

 nal axis. The planes of cleavage are nearly vertical, but dip invariably 

 north or south. 



In a rock section at Shimageri a grey clay rock with silvery talcose 

 surfaces occurs, and probably overlies the calcareous shales. East of 

 Shimageri a large area is covered by purple ferruginous shales, with 

 Hematite sandstones in which occurs a bed of very rich hematite sand- 

 Shimageri basin. stone quartzite of dark-purple color. The section 



is obscure, but this ferruginous bed most likely belongs to the upper 

 quartzites which have been brought to the surface by a small local anti- 

 clinal curve. Similar beds, but much poorer in iron, occur in two or three 

 places in the small synclinal valley at the south-west corner of the basin 

 mentioned at page 133. Hsematite occurs also in the shales in the 

 western corner of the basin, and has been smelted to a small extent. 

 Traces of rich hsematite beds were also noticed on the south side of the 

 Arrakeri synclinal just east of the high road to Sholapur, and also in the 

 bay formed by the Jembigi ridge south-east of Hira (Heera) Chichgundi 

 in Mudhol State. 



Calcareous and argillaceous shales only were observed in the 

 Lokapur basin. 



Intrusive rochs in the Upper Kalddgi series. 

 The only intrusive rocks occurring within the Kaladgi basin are 

 trap dykes, which are very sparingly distributed, and occur only in the 

 upper part of the series. 



The trap dykes are three in number in the Lokapur basin, and one in 

 Dykes in Lokapur ^^^ Arrakeri synclinal valley. They all consist of 

 compact green diorite weathering in concentric
