Abstract
The Kurihashi granitic pluton is one of the plutonic complexes located in Kitakami mountains, and has a golden skarn deposit in the southern part. Rocks constituting the pluton were mainly classified as granodiorite or tonalite. This study is intended to clarify the relationship between the cooling environment of the pluton and the formation of the deposit on the basis of the results of the observation and the analysis of minerals in the rocks.
