Field Geosciences Teaching Module: Geoparks and Geosites Geopark Naturtejo Meseta Meridional Monsanto Inselberg: How does water shapes the landscape?
Geological Map of Naturtejo Global Geopark Monsanto Inselberg
Granite of Monsanto What are the minerals constituting the granite?
Formation of the Inselberg landform Magmatic installation in metassediments from Beiras Group What type of metamorphism occurs during magmatic intrusion in the crustal rocks? Which rocks were formed under the metamorphic zone?
Formation of the Inselberg landform Weathering of granite by water percolation in depth What kind of granite is it taking into consideration the place of formation? What kind of texture does it have?
Formation of the Inselberg landform Exposure of granite by erosion and tectonic uplifting
Boulders field Massif fracturation according with three major fracture directions and weathering Erosion of the edges transform blocks into boulders Where can we find another examples of boulder fields in Naturtejo Global Geopark?
Small scale landforms - Weather pits “Laje das 13 tijelas” Chemical weathering progressively deepens and widens lower areas in the rock such as a mineral missing or a microfracture How are weather pits formed?
Small scale landforms - Tor Accumulation of blocks assuming different shapes in the original position, by removal of the weathering profile
Man and Monsanto How does local geology play a role in the life of Monsanto communities?
