tfPPEE GONDWANA SERIES. 51 



Kandukur laterite area, with exception of a small patch which lies 11 



miles north-north-west of Kandukur, and a little east of the village of 



Ilavara (Yellavurra of sheet 76). The group consists of thirteen separate 



patches, all but three being very limited in extent. Of these three 



the most southerly lies on the 15th parallel of north latitude, close to the 



village of Chinna Latarapy, on the right bank of 

 Chinna Latarapy patch. 



the Vupput-eru. It covers only about 6 square 



miles of surface, but is doubtless connected below t^ie alluvium and 

 lateritic beds with other smaller patches which occur at small distances 

 to the north, east, and west. The well-sections south of Chinna Latarapy 

 show brown micaceous sandstones, sometimes very thin-bedded and 

 pebbly near their base, which rests on the gneiss. The beds have a 

 south-easterly dip, and the plant remains they contain cannot be deter- 

 mined. 



Traces of gritty or conglomeratic sandstone beds, in the shape of 

 patches too small to be mapped, are found dotted here and there over 

 the gneiss inlier east of Chinna Latarapy, and show the contact between 

 the two rock-series very distinctly. Many of the patches are only a 

 few inches across. The sandstone is composed of gneissic debris, chiefly 

 quartzose in character. 



At the western extremity of the western bank at Chinna Latarapy,. 

 thin-bedded friable drab micaceous sandstones are exposed, which show 

 a dip of 2° to 3° to the north-west-by-north. 



South-west of Chinna Latarapy, at the village of Ramnaikenpett, 



drab sandstones with intercalated thin shaly beds

are to be seen; m one well- section they are 



exposed to a depth of 16 feet, and show a dip of 7° to 8° to north-north- 

 west or north-by-west. In the nullah feeding the Ramnaikenpett tank,, 

 the following succession of beds was noted : — 



Sandstone, pinkish-brown.
