CHAP. 4.] KADAPAH FORMATION.—NULLAMULLAY BEDS. 281 
eventually show apparently in two or more bands of slates between 
others of quartzite, which are brought to light again further to the west- 
ward in broken patches of outcrop in the neighbourhood of Mootakoola 
and thence north-east towards Melluvagu. Here, at Mootakoola, they 
show very strongly in the axis of an anticlinal; and the characters there 
displayed are tolerably constant in other limestone outcrops of this part 
of the country. They are generally compact, fine-grained, semi-erystalline 
limestones, and are very often micaceous, or taleose, sometimes extremely 
so with fine laminz of silvery pale green tale. "They are of a slate-grey 
color generally, but tinged more or less of a red purple. Occasionally, 
and when very taleose, they are of a semi-translucent pale green color, as 
at Mootakoola. In one locality* they are pure white, and more crystalline 
than is ordinarily the case; as in a series of strata cropping up 
along the middle of the Waumyconda range of hills north-west of 
Murryvamla. 
At times it is difficult to distinguish beds of this set of limestones 
Often very like lime. from some strata of the KARNULS, as, for instance, 
gosse the Asx و‎ Kakeralla on the Paluad side of the Waumy- 
conda, north of Murryvamla. These are the same as the much more 
crystalline and white vertical limestones in the mountains a few miles 
to the south-west; but further north in the Palnad, there are limestones 
of the KARNÜL rocks which are hardly to be distinguished from the 
Kakeralla beds; only, that the latter are under the quartzites of this 
mountain-ridge, which are themselves subjacent to and much older than 
the limestones in the Palnad. 
The different outerops seen in the country south of the Waumy- 
conda range are very possibly of the same series; or all belong to one 
period of deposition of intermittent calcareous strata, though they are 
* It is here that the most evident cases of reduplication and inversion of the strata 
may be seen. The sharp doubling of the beds here has been too much for their flexibility ; 
and the very altered look of the limestones and quartzites is probably due to a slip of the 
strata over each other in a west-south-west fault.
