Abstract

Betekhtinite occurs in specimens of recrystallised galena from the North Lyell orebody. Its chemical composition is Cu 59.0, Pb 17.3, Fe 2.7, S 20.6, total 99.6. The thermal stability of betekhtinite is briefly discussed.

Zusammenfassung

In Proben von rekristallisiertem Bleiglanz des North Lyell Erzkörpers kommt Betechtinit vor. Dessen chemische Zusammensetzung ist Cu 59.0, Pb 17.3, Fe 2.7 und S 20.6; total 99.6. Die thermische Stabilität des Betechtinites wird kurz diskutiert.

  • Note: According to a recent communication from Prof. F. V. Chukhrov (Moscow), Slavskaya et al. (Journal for Geology of ore deposits, 1963, No. 3) established that at 150°C betekhtinite gives rise to digenite and galena and this mixture is stable at room temperature (results of X-ray investigations). Taking into considerations the pressure, betekhtinite can be formed below 150° C.
