Description

Geological map of the world

This new edition (August 2014) includes the 3rd edition of the Geological map of the world originally published at scales of 1:25,000,000 (3 sheets) and 1:50,000,000 (1 geological sheet), which are now out of print.

The presentation of this new version, centred on the AtlanticThe map has been completely redesigned to fit on a single sheet of paper with improved legibility compared to the 1:50 000 000 version.

D’un point de vue du contenu, la nouvelle carte corrige les erreurs infographiques des éditions de 2010 et, surtout, valorise les données géologiques existentes par un fond physiographique ombré et monochrome, plus atténué sur les continents que sur les océans.  Comme pour la version 2010, elle prend en compte l’état des connaissances sur la géologie de notre planète à la charnière des XXe/XXIe siècles. Des changements de couleur de quelques unités géologiques d’intérêt majeur ont été opérés : volcanisme cénozoïque; trapps; plateaux océaniques, traces de point chaud et monts sous-marins. La représentation des fronts de chevauchement, de quelque nature qu’ils soient (zones de subduction, prismes d’accrétion, chevauchements…) a été homogénéisée.

The leaf Physiography, volcanoes and astroblemsThe 2010 1:50,000,000 edition is still available and can be used as a useful complement to this new map for three reasons: 1) the global physiography is complete and detailed, including isobaths every 1000 m; 2) being Pacific-centric2) the representation of the ocean, which includes most of the planet's subduction zones and hot spots, gives an overall view of this ocean; 3) the representation of active volcanoes can be related to the subduction zones.

Geological map of the world

Some indications concerning the geology:

  • a map showing
  • continental crust/oceanic crust boundary
  • major continental faults and oceanic fracture zones
  • axes of oceanic spreading ridges; subduction zones; sedimentary accretionary prism fronts
  • oceanic morphostructures (seamounts, traces of "hot spots", etc.)
  • representation of the continental shelf (< 200 m)
  • subdivision of the Proterozoic into its 3 eras
  • mapping of the "Large Magmatic Provinces" (LMP) since the end of the Paleozoic (continental trapps, "oceanic shelves") with indication of the average age of the major volcanic episode
  • representation of 45″ hot spots".
  • deformation zones in the oceanic crust (diffuse boundary) between certain plates
  • Meso-Cenozoic ophiolites, etc.

This sheet contains a legend for the land areas, another for the underwater areas and a box corresponding to the 45 "hot spots".

In summary, this map aims to give a better global visualisation of the mega-structures and large geological ensembles that have resulted from the 4.5 billion years of complex history of our planet.
