| Sumario: | This study aims to investigate the mineralogy and diageneticprocesses involved in fossil woods from the Carapacha Formation. Thetechniques applied by X-ray diffraction (XRD) and polarization opticalmicroscopy allowed the recognition and characterization of the phases present:quartz, calcite and iron oxides. The mineralizations follow the pattern of organictextures and with polarized light the plant morphology is distinguished withlight tones. The relationship between the minerals present in the collection ofthe silicified woods and the age of the Formation was considered in order toreinterpret the environment and consider some ecological, climatological andbiogeographical aspects of the vegetation that developed during the Permian. |
