| contents | A triple junction in the Gulf of Mexico: Implications for deep petroleum exploration Jaime Rueda Gaxiola Ciencias de la Tierra Gulf of Mexico salt and redbeds palynostratigraphy mexican oil subbasins deep hydrocarbons exploration Mesozoic redbed and salt sequences have recently been dated using a palynostratigraphical method developed at the MexicanPetroleum Institute (IMP) since 1975. They represent the early Mesozoic marine transgression which formed the petroleumsystems. The information from 1969 to1993 for the Rhaeto-Liassic redbed Los San Pedros Allogroup and Huayacocotla Group(Huayacocotla-El Alamar Basin), Middle Jurassic La Joya Formation (Chihuahua Sabinas Sub-basin), Middle Jurassic Rosarioand Cahuasas formations (Tampico-Misantla Sub-basin) and Middle Jurassic Todos Santos Formation (Veracruz and Southeasternsub-basins) and Middle Jurassic salt units (Southeastern sub-basins) and the caprock of the Challenger Knoll, drilled in theGulf of Mexico, are reviewed.After these data an unconformity between the igneous-metamorphic basement and the Middle Jurassic redbeds in some subbasinsof the Gulf of Mexico, and between the Liassic sedimentary rocks and the Middle Jurassic redbeds in the Huayacocotla-ElAlamar, Tlaxiaco and Huamuxtitlán basins is proposed. The Triple Junction Model includes three different periods: (1) the formationof one or two Rhaeto-Early Liassic wrench or shear basins (Huayacocotla-El Alamar); (2) formation of the Tampico-MisantlaSub-basin during Late Liassic, and (3), the origin of the Gulf of Mexico Basin and the Chihuahua-Sabinas, Veracruz and Southeasternsub-basins during the Early Middle Jurassic. A triple junction system allowed the northwestward displacement of theTexas-Louisiana Block and the western region of Mexico away from the stable Chiapas-Yucatán Block along the Vancouver-Bahamas and Texas-Sabinas alignments and the Pico de Orizaba-Laguna Inferior Megashear.From geochemical data oil and gas-producing provinces are predicted in continuation of the Chihuahua-Sabinas, Tampico-Misantla and southeastern sub-basins. 2004 artículo científico 0016-7169 https://www.redalyc.org/articulo.oa?id=56843306 en http://www.redalyc.org/revista.oa?id=568 Geofísica Internacional application/pdf Universidad Nacional Autónoma de México Geofísica Internacional (México) Num.3 Vol.43 |
