National Geology Weekend 2023.


At a time of growing concern about the state of the planet and its environment, the French Geological Society (SGF) organises an annual event supported by various organisations across France working in the field of geosciences. The event aims to engage with the general public and raise awareness about the Earth’s precious resources and the beauty and history of its natural landscapes.

In 2023, BRGM will once again be a partner of the National Geology Weekend organised by the French Geological Society. The event will take place from Friday 26 to Sunday 28 May 2023.

Aimed at the general public, the National Geology Weekend seeks to raise awareness about geosciences through the organisation of conferences, tours and excursions, most of which are free of charge.

Conference on "Mineral resources in everyday life"

Friday 26 May at 7pm
Never have we consumed so many mineral resources, including metals, sand, oil and gas. Although the general public is often unaware of the fact, these resources are used in every sector. These are just a few of the examples that the geologist will discuss in relation to the challenges of the energy and digital transitions.
