Orogens develop in convergent settings involving two or more continental and/or oceanic plates. They are traditionally defined as zones of crustal deformation associated with mountain building resulting from either accretion of a terrane and/or an arc, continent-continent collision or rift-inversion. However, this definition does not consider the g...

Orogens form in convergence settings involving two or more continental and/or oceanic plates. They are traditionally defined as zones of crustal deformation associated with mountain building resulting from either the accretion of an arc, a continent-continent collision or the inversion of a rift basin. However, this somewhat narrow definition does...

A l'occasion des Journées Nationales de la Géologie, la CCGM vous propose un atelier/conférence pour (re)découvrir la Charte Stratigraphique Internationale, la Carte Géologique du Monde et le Globe Géologique terrestre. L'objectif est essentiellement pédagogique (la Carte Géologique du Monde figure au programme de SVT de 1ère et Terminale S) et vo...

The Indian Ocean has witnessed some of the most important geodynamic events that shaped our present-day Earth during the last plate tectonic episode. From the early fragmentation of the Gondwana super-continent sustained by an intense hotspots activity to the real-time birth of a new volcano in 2019 in the Comoros Archipelago, almost 200 Myr of geo...

Because of the outbreak of the global Covid19 pandemic, the 36th IGC scheduled between March 2nd and 8th, 2020 had to be cancelled and postponed to August 2021. Along with this event was our CGMW General Assembly and our Bureau Meeting. As some members of our community were not in the position to reschedule their journey, we have chosen to postpone...

The Earth Geological Globe is based on the revised 3rd edition of the Geological Map of the World, originally drawn at the scale of 1:25 million, published in 2014 by the Commission of the Geological Map of the World (CGMW). It integrates the state of the art of the geological knowledge of our planet at the turning-point of the XX/XXI centuries. Th...

The Arctic is a critical region in terms of environment, tectonic, energy and mining resources. This new project under the head of the CCGM is built around an Earth / Sea tectonic map highlighting the link between the structures of the margins and the crustal nature (oceanic / continental stretched) of the Arctic basins. It is not only a tectonic m...

This new edition (August 2014) reconsiders the 3rd edition of the Geological Map of the Word, published initially in 2010 at the scales of 1:25 000 000 (3 sheets) and 1:50 000 000 (1 sheet Geology, structure), both presently out of print. The layout of this new version, centered on the Atlantic, was redesigned in order to fit a single sheet, while...

World Gravity Map (WGM) denotes a set of 3 global anomaly maps of the Earth’s gravity field realized by the Bureau Gravimétrique International (BGI), a service of the International Association of Geodesy (IAG). These new products, realized for the Commission for the Geological Map of the World (CGMW), UNESCO, International Union of Geodesy and Geop...

The Physiography, volcanoes, astroblemes Map displays a complete image of the Earth's reliefs (including the ocean floor) with distribution of 1507 active volcanoes and 198 meteoritic impact craters (sorted in 2 categories of diameters), including a legend and some remarquable features of the planet's morphology.

This map is the first global compilation of the wealth of magnetic anomaly information derived from more than 50 years of aeromagnetic surveys over land areas, research vessel magnetometer traverses at sea, and observations from earth-orbiting satellites, supplemented by anomaly values derived from oceanic crustal ages. The objective is to provide...
