Abstract
Poughite, frohbergite, and melonite are found in ore samples from the Kobetsuzawa Mine in Hokkaido. Poughite is associated with secondary minerals, tellurite, anglesite, cerargyrite, and limonite. Occurrence of the mineral appears to have derived from the alteration of pyrite, altaite, and hessite. Frohbergite and melonite are associated with altaite, hessite, petzite, tellurantimony, native tellurium, sylvanite, rutile, chalcopyrite, stibnite, pyrite, and arsenopyrite. Such complicated association of the tellurium-bearing minerals with rutile is rare in nature.
