Geosito Lemme - Carrosio
Museum | Carrosio | Piemonte | Italy
The Geosito Lemme - Carrosio in the Piedmont region of Italy is a geological site of international significance, as it marks the Global Stratotype Section and Point for the beginning of the Aquitanian stage. This point has been recognized by the International Commission on Stratigraphy and serves as a reference for the geological time scale.
Geological significance:
The Lemme-Carrosio GSSP is located in the Rocchetta-Monesiglio Formation of the Piedmont Tertiary Basin and represents the transition from the Oligocene to the Miocene. The sequence consists mainly of thinly bedded marls and siltstones deposited by turbiditic processes. This site provides valuable insights into the climatic and ecological changes that shaped the end of the Oligocene and the beginning of the Miocene.
Fossils and paleontology:
The Geosito is rich in fossil remains, especially of microorganisms such as foraminifera and radiolarians, which are important for biostratigraphic dating. These fossils allow for a detailed reconstruction of environmental conditions and biological evolution during the transition between the Oligocene and Miocene.
Access and visit:
The Geosito Lemme - Carrosio is accessible for scientific studies. However, visitors should be aware that access to geological sites is often restricted to protect the integrity of fossils and geological formations. It is recommended to inquire about the current access conditions and any guided tours before visiting.
Significance for science:
This Geosito plays a central role in geological research as a reference point for the definition and dating of the Aquitanian stage. Its well-preserved sequences and fossils provide valuable information for stratigraphy, paleontology, and climate research.
Overall, the Geosito Lemme - Carrosio represents a significant geological site that is not only of interest to science but also highlights the geological heritage of the Piedmont region.
