Abstract: The oxidation of pyrrhotite and pyrite initiates a series of weathering reactions in aggregates extracted from the Mont Palau quarry (Barcelona, Spain). The lithotypes enclosing the sulfides, however, play an important role in controlling the progress of weathering: whilst expansive hydrated Fe-sulfates characteristic of acidic environments formed in the black shales, the neutralizing capacity of calcite dissolution prevents the formation of these harmful mineral phases in the limestones.
Sponsor: This study received financial support from the Spanish Government CICYT PAT91-0992 project.
