PETROMETALLOGENIC UNITS RELATED TO MAGMATIC DOMAIN-DISTINGUISHING CRITERIA

摘要

The lack of a single and unanimously accepted opinion regarding the systematics of metallogenic-petrometallogenic units and their identification led in time to regretable inconsistences. Initially, the metallogenic units and subunits based on economic criteria and on the spatial (geographical) distribution of ores have been taken into account. Later on, new criteria based on geological elements have been involved (according to Launay, de L., 1913; Emmons, 1913; Lindgren, 1933; Bateman, 1956; Petraschek, 1965 and many others).
