Abstract

This study is made for examining the characteristics of the lead-zinc deposition from the mineralogy of pyrrhotite at the Yeonhwa 1 Mine, Korea. The pyrrhotite of the Yeonhwa 1 mine is divided two species; the pynhotites I and II. The pyrrhotite I that represents the product in Stage II mineralization is characterized by hexagonal pyrrhotite occurring as the mechanical mixtures of hexagonal and monoclinic phases with various proportion. These mixtures might be formed from 'primary' hexagonal pyrrhotite by the subsequent retrograde reaction and/or by the influence of later mineralization in Stage III. Whereas the pyrrhotite II crystallized out in later Mineralization Stage III (hydrothermal stage) is always monoclinic variant with ferromagnetic properties; no two phase mixtures have been recognized.
