| The object of this article is to offer a synthesis of the knowledge clarifying the originality and the diversity of the submarine geological formations of the New Caledonian EEZ. A reminder is given onto the geologic history of the region, based upon the dislocation of the Gondwana Continent, the opening of the Tasman Sea, the presence of submarine volcanism, the setting up of heavy peridotitic rocks, the building up of the Fairway and Lord Howe Ridges and of sedimentary basins, the formation of volcanic domes and sea-mounts or guyots, the subduction along the Vanuatu Trench, the uplift of the Loyalty Islands, the development of carbonated ptatforms around the islands etc.... Of this complex history ensues an exceptional submarine geo-diversity. After this... |

| This article of the number 10 of Tai Kona is the natural complement to the article appeared under the number 8, dedicated to the submarine geodiversity of the New Caledonian EEZ. The first article notably put the bases of knowledge on the history, the origins and the specificities of the geodiversity of the maritime spaces of the New Caledonian EEZ. The present article focuses on four of the major stakes which are put: 1/ the scientific ones relative to an exceptional submarine geologic context, 2 /the economic ones connected to such a favorable geologic context and to mineral resources exploitation perspectives which are no more domain of the utopia, 3/ the major environmental ones with the existence of a semi deep and deep major biodiversity and 4/ the... |

| The southwestern Pacific Ocean region hosts submerged continental margins, ridges, sedimentary basins, and volcanic arcs located around Papua New Guinea, New Zealand, Australia, and Fiji. The geological history of this vast region has remained controversial, and to improve understanding of the processes that controlled its geodynamical evolution, it is essential to place each piece of available data in a regional spatiotemporal framework. To this end, a new map, entitled “Structural Provinces of the Southwest Pacific,” was released by the Geological Survey of New Caledonia in May 2011. The publication consists of two parts: (1) a 40-page booklet of geological notes, which documents the nature and age of each structure and contains an associated list of... |
