Description
Summary:	This paper is a revised version of previous interpretations of the Caribbean structure submitted by the authors to various geological conferences and meetings (mostly unpublished). The fundamental idea consists in postulating a maximum thickness of 5.000± m. of Cretaceous-Tertiary sediments, in an essentially geosynclinal basin, some 100 km, off shore, in approximate coincidence with the free-air gravity minimum and the magnetic anomaly maximum. The stratigraphic and structural interpretation is based on the correlation originally proposed with the Salamanca drill-hole and available surface gravity and geology information (DURÁN,1964), but corrected with recent JOIDES' Program data. For the isostatic anomaly a different generalized interpretation is suggested instead, in terms of the new plate tectonics ideas. It is believed that oil-bearing structures may be present off shore, in spite of the negative results obtained heretofore in land, or on shallow shelf. This reinterpretation (still tentative) is mainly based on partial recent Infermation from R/V Trident (Rhode Island Univ.) and R/V Conrad (Lamont-Doherty, Columbia Univ.) cruises; on publications and recent discussion and communications,principally with Drs. M. Ewing, M. Talwani, D. Krause and E. Christofferson.
