Abstract
It is possible to determine the paragenesis of the nine ore minerals and eleven skarn or gangue minerals in the deposit of Ômine mine by microscopic examination. On the other band, there are at least eleven kinds of unmixing intergrowth found in the metallic minerals, as has been reported previously. The unmixing temperature of them is known only in a few cases of them. Hereunder, the ouder of the 11 unmixing intergrowths, is assumed by introducing some hypotheses on unmixing, and combining the results with the paragenesis of the ore minerals determined by microscopic examination, in order to unravel the process of growth of the ores. However, there are as yet some details which require further research.
