- Foundations of Gulf of Mexico and Caribbean evolution: eight controversies resolved K. P. Stanek W. V. Maresch G. Draper J. Pindell L. Kennan Ciencias de la Tierra Proto Caribbean Gulf of Mexico Pacific origin Tectonic evolution Eight points of recurring controversy regarding the primary foundations of models of Gulf of Mexico and Caribbean tectonicevolution are identified and examined. The eight points are controversial mainly because of the disconnect between differentscales of thinking by different workers, a common but unfortunate problem in the geological profession. Large-scalethinkers often are unaware of local geological detail, and local-scale workers fail to appreciate the level of evolutionary precisionand constraint provided by regional tectonics and plate kinematics. The eight controversies are: (1) the degree of freedomin the Gulf-Caribbean kinematic framework that is allowed by Atlantic opening parameters; (2) the existence of aSouth Bahamas-Guyana Transform, and the role of this structure in Cuban, Bahamian, Trinidadian, and Guyanese evolution;(3) the anticlockwise rotation of the Yucatán Block during the opening of the Gulf of Mexico; (4) the Pacific origin ofthe Caribbean oceanic crust; (5) the Aptian age and plate boundary geometry of the onset of west-dipping subduction ofProto-Caribbean beneath Caribbean lithospheres; (6) the origin and causal mechanism of the Caribbean Large IgneousProvince not Galapagos!; (7) the number and origin of magmatic arcs in the northern Caribbean; and (8) the origin ofPaleogene flysch deposits along northern South America: the Proto-Caribbean subduction zone. Here we show that thereare viable marriages between the larger and finer scale data sets that define working and testable elements of the regionsevolution. In our opinion, these marriages are geologically accurate and suggest that they should form discrete elements thatcan and be integrated into regional models of Gulf and Caribbean evolution. We also call upon different facets of the geologicalcommunity to collaborate and integrate diverse data sets more openly, in the hopes of improving general understandingand limiting the publication of unnecessary papers which only serve to spread geological uncertainty. 2006 artículo científico 1695-6133 https://www.redalyc.org/articulo.oa?id=50540217 en http://www.redalyc.org/revista.oa?id=505 Geologica Acta: an international earth science journal application/pdf Universitat de Barcelona Geologica Acta: an international earth science journal (España) Num.1-2 Vol.4
