Economic geology - Genetic classification of ores
This document discusses genetic classification of ore deposits. It notes that while various geological aspects like metals, orebody form, environment, and tectonic setting are used to classify deposits, a stringent genetic classification is difficult for two reasons. First, many deposits represent complex combinations of well-defined end members like volcanic, intrusive, sedimentary and diagenetic processes. Second, the origin of deposits like Kuroko and high-grade BIF-haematite seems to involve multiple geological processes interacting, like marine life proliferation and saline brine passage. The document recommends reading a specific review article for further detailed classification information.

Genetic Classification ofOre Deposits Various geological aspects are employed to classify ore deposits, including: 1.the presence of certain metals or minerals (e.g. silver, haematite); 2.the form of the orebody (vein, bed, etc.); 3.the local geological environment (submarine or terrestrial volcanism); 4.the plate tectonic setting (island arc, continental margin) and 5.other genetic characteristics such as formation temperatures and fluid chemistry. However, a stringent genetic classification of mineral deposits is very difficult. One reason for this is that many ore deposits represent a position in a complex multi-dimensional space of well defined end members: 1.The formation of Kuroko ore deposits, for example, is an interplay of volcanic, intrusive, sedimentary and diagenetic processes; 2.The origin of high-grade BIF-haematite ore seems to comprise sedimentation induced by proliferating marine life, later passage of saline basinal brines and
