Not very far to the north of this scries and still to the south 
of the present position of Ani village, medium-grained hornblende - 
granite crops out. To the north of Ani village is an outcrop of 
leucocratic pink coarse-grained granite with both white and red 
felspars and subordinate quartz and biotite. The felspar is some- 
times in graphic intergrowth with quartz, and the rock suggests 
the irregularly pegmatitic granite dykes found in the Nakta Nala, 
Chhindwara. Associated with this granite is a melanocratic epidote- 
hornblende-gneiss, probably a metamorphosed dolerite. Further 
north some bedded fine-grained granulites were crossed, followed 
by a considerable extent of crushed biotite-gneiss. In the Gej 
Nala, pink bead gneiss and coarse-grained, red, very felspathic 
gneiss are exposed. The general strike of the rock of this inlier 
is E. N. E., in places vertical, and in places with a moderate to 
steep dip to the south. 
The rocks of the Siroli inlier lying at the western end of the 
State, and traversed by the Hasdo river, consist, as far as ex- 
amined, of porphyritic biotite granites, often

gneissose, and sometimes converted into augen- 
gneiss. They are associated with fine-grained grey gneiss with 
scattered phenocrysts. The strike varies from E. by N. to E. by S.

S. W. of the Siroli inher also consists of

On crossing from the Archaean group to the Talchirs, one 
is often very puzzled as to where the exact

fact that the Talcnirs were deposited on a 
hilly and extremely irregular surface of Archaean rocks, many 
of the summits of the Archaean hills now protruding through 
the Talchirs. This phenomenon is exceedingly well seen in the 
Phunga Archaean inlier, where small patches of Talchirs, identifi- 
able by the character of the boulders, are found scattered about 
on the granitic massif. No general elevation, therefore, can be 
assigned to the Talchir-crystalline boundary, for most of the 
Archaean inhers stand up as peaks from the shrouding Talchirs 
which, generally speaking, occupy the lower ground. Compare, 
for instance, the height of Dewadand, 1,273 feet, with that of 
Phunga, 1,671 feet. The most marked exception to this state 
of affairs is the peak known as Churi, which, as seen from
