On some tellur minerals and their textures from Okuyama and neighboring mines, Izu Peninsula

Abstract

Some tellur minerals (altaite, tetradymite, and hessite) in the epithermal copper-quartz veins of Okuyama Mine, Izu Peninsula, are determined microscopically and also the relation between the ore textures of some mines (Aono, Kawazu, and Suzaki) in this district and the geneses of these deposits are discussed.
