Geological map of the world at 1/35 M

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.

From a content point of view, the new map corrects the infographic errors of the 2010 editions and, above all, enhances the existing geological data with a shaded and monochrome physiographic background, which is more subdued on the continents than on the oceans. As with the 2010 version, it takes into account the state of knowledge on the geology of our planet at the turn of the 20th and 21st centuries. The colour of some major geological units has been changed: Cenozoic volcanism, traps, oceanic shelves, hot spots and seamounts. The representation of thrust fronts, whatever their nature (subduction zones, accretionary prisms, thrusts, etc.) has been homogenised.

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.

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".

From explanatory notes centred on the commentaries of the different captions are available for free download in pdf format (French version), to download them click here.

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.
