Inventory and assessment of geosites to stimulate regional sustainable management: the northern coast of the state of São Paulo, Brazil.

The reviewed and integrated geoheritage inventory of the northern coast of the state of São Paulo, Brazil, resulted in 43 geosites distributed in eight geological frameworks. The selected geosites are representative of a geological history from the Neoproterozoic (Brasiliano-Pan African Cycle) to the recent, covering a minimum 700-Ma timespan. Considering the dynamic character of geoheritage inventories, the results presented in this work were based on previous local, town-based surveys, which were reviewed under the light of new geological data and geoconservation methods.

Multi-technique investigation of potshards of a cerrito (earthen mound) from southern Brazil.

The physicochemical investigation of ceramics crafted and managed by ancient humans allows a better understanding of their social, technological, economical, routine and artistic activities. The Brazilian State of Rio Grande do Sul presents the biggest number of registered archaeological sites in the country, and many of them are earthen mounds, locally known as cerritos de indios. This kind of archaeological site is of utmost importance to understand the social development of the biome Pampa - including areas from Brazil, Argentina and Uruguay - and almost nothing is known about the physicochemical composition of the artifacts from the Brazilian portion.
