Abstract
The contact metasomatic and the vein-type ore deposits of the Shin-Kiura tin mine have been worked since old times for tin, silver, arsenic and copper. These are characterized by complex mineralization at a wide range of temperature related to the Tertiary granitic intrusion. Recently, lollingite-cassiterite-quartz-wollastonite vein-like deposits, containing native gold, native bismuth and tellurobismuthite, have been found in the Uriya-Kaneko adit of this mine.
In this paper, mineragraphy of the Au-Te-Bi-As ore is presented, and genesis of the similar mineralizations in Japan is discussed.
