Abstract

Electronprobe microanalyses were made of enargite and luzonite from various localities. It was shown that enargite can contain as much as 6 wt.% antimony. Complete solid solution was observed between the tetragonal phases luzonite and famatinite. The compositions of enargite and of luzonite-famatinite solid solution were found to be very variable even within one polished section.

Zusammenfassung

Anhand quantitativer Elektronenstrahl-Mikroanalysen von Material verschiedener Lagerstätten wurde festgestellt, daß Enargit bis zu 6 Gew.% Antimon enthalten kann. Zwischen den tetragonalen Phasen Luzonit und Famatinit wurde völlige Mischbarkeit beobachtet. Es wurde gefunden, daß die Zusammensetzung von Enargit und Luzonit-Famatinit selbst im Bereich eines Anschliffes stark schwanken kann.
