Sedimentology and ore genesis / Седиментология и рудообразование (осадочное рудообразование)

Historically, the relation between sedimentology and the field of ore genesis has been a function of prevailing patterns of thought. Table I offers a brief schematic summary of the trend of thought patterns since Albertus Magnus.
Whenever the trend was to search for causes from within, the interest in the wall rock and its genesis was great. When causes from without appealed more to the scientists, the rocks enclosing ore deposits, and especially the sediments received little attention.
The present generation inherited largely the latter type of thinking; so much so, as a matter of fact, that sedimentary petrology was treated as a step child in petrology courses. An “economic geologist” was not required to have a serious interest in “soft rock petrology”. The ore in “soft rocks” was a priori believed to have come from “hard rocks” at unknown depths, and the magic word which solved all the problems was “replacement”. <...>
