Abstract
The chemical composition of biotites and sericites from the Cerro Verde porphyry copper type deposit have been investigated in detail, using an electron microprobe. The main results of the study are: Al/sup vi/ and Ti contents of biotites of magmatic as well as hydrothermal origin may be related to the temperature of crystallization estimed by independent methods. On the other hand the Mg/Fe and Mg/(Mg + Fe) ratios are almost constant. This fact is interpreted in terms of fO/sub 2/; sericites have a phengitic composition in which the solubilities of the two end-members celadonite and paragonite are controlled by a fluid phase under P, T conditions that could be estimated.
