The Economic Geology of Orissa (with a Mineral Map of Orissa)

1949

W. The disposition of the later formations has been determined to a great extent by the trend of the Archcan rocks the parallelism between the strike of the Archeans and the trend of the Gondwana outliers being particularly noteworthy. [...] On the basis of the presence or absence of garnets in the rocks Sir L. L. Fermor some 20 years ago drew a dividing line across the region : the garnetiferous varieties to the south were called the Eastern Ghats facies and the non-garnetiferous rocks to the north were called the Chota Nagpur facies. [...] It may be pointed out that the trend of the schistose inclusions in the gneisses the strike of basic rocks and khondalites and the trend of the Cuddapahs and Gondwanas all conform to the foliation of the gneisses in their neighbourhood. [...] That survey must be based on the geology of the province for apart from a few of the organic acids and carbon the soil derives the whole of its constituents from the rocks."14 SOIL EROSION In Chapter 11 the sequence of uplifts which has given rise to the plateaux of the Eastern Ghats were outlined. [...] Theoretically then the value of the mineral in the ground is the difference between the sale price of the raw material and all labour and other charges from the moment of commencement of mining it.
