Memoirs Geological Survey of India. The Mineral Deposits of Eastern Singhbhum and Surrounding Areas

1937

The survey of the eastern part of the Singhbhum copper pelt was commenced 'in November 1927 ; subsequent to the completion of mapping along the copper belt the survey . was extended to a much wider area until the 1934-35 field season, using the Survey of India maps published on the scale of one inch to one mile. [...] He was the first to point out, in his progress reports, the intrusive nature of the granites into the schists, he also suggested the relation of -mineralisation . to the Singhbhum granite and the localisation of the copper deposits to interlaminated zones of crush. [...] The simple expression ore4iquid fulfils all the requirements and makes no' admission of the physical relation between the constituents therein ; the term does not exclude the presence of material in col- loidal suspension at any stage_ in the history of the liquid. [...] occur in a lode, the order of deposition of the minerals lining the vughs, the coating of one mineral by another, is of particular significance. [...] The replacement of one mineral by another, which provides a picture of the seqnence of changes and of the stability conditions during the history of the ore- liquids, is, like the mineral sequence itself, one of the fundamental facts upon which metallogenetic arguments are based.
