Abstract:
long back in 1884, before the cerbo natite were
recognized as petrolo gtcclly end economically! si nifica
type of roc cs P, N.Bose,whiie investigating the geology of
the armado valley between N mtmar and Kawant near Dot,
came across those carbonate rocks, and the observation which
be made became the first ever recorded description of a
car bo ratite ;,
He observed masses of yellowibalterod caic reous
siliceous rocks forming the crest of baaalt'coverod ridges.
He bas .sated
1, " that these reeks were rxro resistant to ventherin and
erosion than basalts,
2 * that they were not bedded
3, corztnodm fossils
4. that they ware fix pained but crystalline
5, that they were markedly calcareous with to eal nests and
patches of trappean400k1g substance— the igneous origin
of a.icb manifesto under the microscope
8, the outcrop distribution is lenior and straight
7. that they were locally associated with highly altered and
