SCJHISTOSE areas. 21 



the two northern ones have probably been inverted by faulting of the 

 strata. These beds form the Vemparala group. 



To the eastward of the Gundlakamma magnetite beds, the band of 

 schistose gneiss is greatly encroached upon by the granitoid gneiss band, 

 leaving but a very narrow belt of the former between the granitoid band 

 and the younger sedimentary rocks fringing the coast. The schists 

 occupying this narrow belt are mainly hornblendic, but are of no special 

 interest. 



Two or three rather poor beds of magnetic iron occur within the 

 limits of the granite gneiss band west of the Gundlakamma, to the east 

 of Purimetla (Pooreemetta) tank, about 4 miles west of the last-men- 

 tioned set of beds near Vemparala. But for their exceptional position, 

 these beds offer nothing of any interest. 



It was mentioned above (page 17) that one instance had been noted 

 Hematite schist near of the occurrence of hsematitic schist in the gneissic 

 Chtmdi. region. This was seen in the Chundi hills, west 



of the village of Polenane Cheruvu, where several hsematitic beds occur 

 associated with a great thickness of micaceous clay and flaggy schists. 

 One or two of the hsematitic beds are rich, the remainder poor and of no 

 importance. Their northern and southern extensions are lost sight of in 

 the extensive low jungle which covers all the ridges in that quarter. 



Before concluding our references to the eastern schistose band, we 



must consider three other sets of quartzite beds

which belong to it. Two or these are associated 



with the Chimakurti outlier of trappoid, or intensely hornblendic, 

 granite gneiss above referred to (page 10), and lap round it as if under- 

 lying it conformably and forming the walls of a surrounding synclinal 

 ellipse. Of the real infra-position of these quartzites to the hornblendic 

 beds, there can be no doubt on the western side of the Chimakurti hills, 

 but on the south-eastern and northern sides the quartzites are not seen, 

 but are either wanting or obscured by talus deposits. They show well for 

 about 4 miles on the eastern side of the ellipse, but are inverted at
