Abstract

This article briefly discusses the world distribution of mercury deposits. These are classified according to their associated minerals: mercury alone, mercury-antimony, mercury-arsenic, mercury-antimony-arsenic, mercury-lead-zinc and mercury-quartz-gold. The deposits are also categorized by the types of rocks in which they occur and by the geologic structures with which they are associated, i. e. (in beds at the crests of anticlinal structures, on the flanks of folds and at the intersections of ore-bearing strata with faults; in thrust sheets and linear zones of fracturing; as veins within tectonic ruptures; and in local structures of varying origin. The metallogenic ages of the ore occurrences are grouped in five categories: Alpine (Tertiary and Quaternary), Mesozoic, Hercynian, Caledonian and older, and undetermined. Some details are given on the times of mercury mineralization in the history of the folded areas, the emplacement of the deposits in particular parts of folded systems, and on the extent of...
