| Abstract: | Oxidized chlorites, having optical properties quite similar to those of biotite, stilpnomelane or iron-rich vermiculite, are described from the schistes lustrés and other similar metamorphites of the Pennine Zone of the western Italian Alps. Optical, x-ray, chemical, DTA and infrared spectroscopic data are furnished. From the results of the chemical study it seems reasonable to conclude that the chlorite has undergone an internal oxidation. Possible petrogenetic implications of its occurenee are discussed in some details. |
