Patinas developed in environmental burial conditions: the Neolithic steles of Reguers de Seró (Lleida, Spain).

Background, Aim And Scope: Weathering patinas in rocks are the result of interaction processes between rock surfaces and atmosphere, biosphere and soil. Therefore, their textural and mineral composition is strongly related to environmental and bioactivity conditions. Whereas the development of weathering patinas in atmospheric conditions is well documented (e.
