290 KING: KADAPAH AND KARNÜL FORMATIONS. [PART IV. 
overwhelming evidences of contemporaneous trap flows; but the silicio- 
felspathie roeks are not nearly so clear as to their structure or origin. 
Again, Mr. Charles A. Hacket, who carried on the working out of 
Aper d dun the vINDHYANS towards Gwalior, found that they 
Eo Gone aon. are unconformably overlying a series of rocks 
which he called the Gwaliors. These consist of sandstones, limestones, 
and shales with flows of contemporaneous trap, all answering very 
much to the rocks of the Tadapurtee (Poolumpett) sub-group of 
the kApAPAH formation on the western side of our area. The collection 
of rock-specimens from the Gwaliors can be matched every now and 
then by specimens from the KADAPAHS in a most remarkable way. 
The red and black striped ferruginous Jasper shales are common to. 
both ; indeed, specimens of these from Gwalior might be taken at once 
for fragments of jasper beds below the western scarp of the Oopalpad 
plateau. The brown and black jaspers are also just as like in both 
formations. 
The *non-deseript quasi-felspathic’ rocks of the Gwaliors are like 
the spotted and speckled shales of the Penn-air and Chittravutty valley : 
only that they are harder and more compact, and likewise more 
erystalline. 
The cherty rock with a quasi-organie structure of the Gwaliors is, 
except in the form of its organic-looking contained bodies, like the oolitoid 
chert of the Vaimpully limestones; and the ‘coralloid chert with 
limestone? is somewhat like our segregated limestones in the same group. 
The Par quartzites of Mr. Hacket might be the same as altered 
beds of the like constitution in the Naggery or Goolcherroo quart- 
zites, though according to position it would answer best to the latter. . 
The great resemblance, however, between the Gwalors and the 
KADAPAHS is in the jasper beds, the spotted felspathie rocks, or 
possible ‘ash beds,’ and the presence of contemporaneous traps among 
these.
