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) & 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 the legibility was enhanced in relation to the reduced version at 1:50 000 000.
