| Abstract: | 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.g. typical Mediterranean patina), only
very few studies focus on their formation in a burial environment. Our study of patinas developed on the tumular structure
of Reguers de Seró deals with the knowledge of burial patinas from a textural and mineralogical point of view. The aims of
this study include: (1) the characterisation of the rock used in this megalithic monument as well as inferences regarding
the origin of the raw material; (2) the evaluation of the patinas developed on the surface of the carved steles; and (3) the
discussion of the environmental conditions (atmospheric or burial) that favoured the development of the patinas. |
