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 belt 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. [...] 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 ore-liquid 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 segnence 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.
