Brief description
This geosite allows one to observe in detail, or in an overview, the sequences of subaerial basaltic flows and conglomeratic and breccioid deposits (lahar type) of the Penha d'Águia Formation, that belong to the Intermediate Volcanic Complex (CVM). Due to its integrity and representativeness, this set of outcrops should be used as a reference when characterizing this stratigraphic formation.
This site was chosen over the one located in the Penha d’Águia region (the place that gives the name to the stratigraphic formation and defines its simple stratotype), for its easy access and excellent visibility conditions. Here, the diversity of geological elements is also of superior value.
Relevant notes
Visiting a site of geological interest is the sole responsibility of the user.
The user must take precautions when visiting the site, taking into account the conditions of the terrain, weather conditions and other hazards, so that they do not create situations that put themselves or others at risk.
The user must respect private property. Access to private areas requires prior authorization from the owners.
The user must respect natural heritage, keeping it intact. The impact of your actions should be minimal.
Protection status
Natural spaces – Natural spaces of very conditioned use – scarp zone (Article 50º), according to the Municipal Master Plan.
