' The granitic intrusions in tlio schist series which Ncwbold regarded as intru- 
sions of the granit;)id mass aio all found to be intrusic-ns of much younger pegma- 
toid veins, and of very small extent and importance'. 
It is curious how ideas change. During the last few years the 
Geological Survey of India has been arriving at the conclusion that 
these very crystalline granites, showing little or no evidence of having 
suffered structural deformation under the influence of tectonic move- 
ments, are really younger in age than the crystalline schists and foliated 
and schistose gneisses, which all show such abundant evidence of having 
been subjected to prolonged and severe compressive movements. Thus 
the Bundelkhand Granite is younger than the Bengal Gneiss, the Bellary 
Granite than the Salem Gneiss. Similarly the Dharwar rocks, being 
less severely metamorphosed forms of portions of the ancient schists and 
gneisses, are now regarded by some as older than the Bundelkhand and 
Bellary Granites. The evidence of intrusive relations that Foote had 
not discovered have since been found in more than one part of India, 
as, for example, by myself at Jothvad in Narukot State, and by the 
Mysore Geological Department at several localities in Mysore' . 
Capping the Ramandrug ridge, on which it gives rise to a plateau 
and also covering a considerable portion of the 
titfe'brecdes!"''' '""'^ Kamataru plateau, is a rock that Foote refers to 
as ' pseudo-laterite ' in the following words 2; — 
' The summit of the Ramandrug ridgo is very frequently much obscured by 
hsematitic debris which occurs in two forms : firstly, as an ordinary pseudo-laterite, 
either massive or encrusting, and secondly, as a breccia of angular fragments of 
haematite rock, often very rich in iron and of a deep reddish or blackish purple 
colour. The enclosed fragments are of all sizes. Masses nf the haematite rock 
in situ often protrude through the overlying breccia, and where the beds are much 
crumpled it is often hard to be sure whether the protrusions are parts of the breccia 
or part of the rock in situ. These protrusions are so frequent and large that the 
breccia cannot be shown on the map as a continuous deposit'. 
As far as I could see there was every passage from this ' pseudo- 
laterite ' into the hematitic breccia, the ' pseudo-laterite ' being formed 
from the breccia by chemical alteration, in which the iron oxide of the 
hematite passes into solution and gets redeposited in the hydrated
