Cerro prieto and its relation to the gulf of California spreading centers

The Cerro Prieto geothermal field is located in the Mexicali Valley, Baja California. Tectonically, this northern part of the Gulf of California has been classified as a spreading center, within a transitional area of oceanic to continental conditions.

Tectonically, this northern part of the Gulf of California has been classified as a spreading center, within a transitional area of oceanic to continental conditions. Thermal, geologic-tectonic and magnetic evidence has been used to postulate the existence of a heat source in the area that is associated with magmatic processes, similar to those that occur in a typical oceanic spreading center. Based on the petrography and geochemistry of the volcanic rocks obtained during the drilling of the Wells in the geothermal field, the rocks were classified as: basalts, basalt-andesites, andesites and dacites. The petrogenetic model of the intrusive volcanic bodies that is proposed for the area of crustal spreading at Cerro Prieto is different from the one proposed tor a typical oceanic spreading center, as is the case for the spreading centers located in the Gulf of California. This region of continental basaltic magmatism is complex due to: a) chemical composition and mineralogy of the mantle source, b) partial melting of the parent magma, c) magma segregation depth, and d) extension of the fractioned crystallization and the melting processes during the storage of the magma in the upper levels of the magmatic chamber.El campo geotérmico de Cerro Prieto se localiza en el valle de Mexicali, Baja California. Tectónicamente, ha sido clasificado como un centro de dispersión, ubicado en una zona de transición de condiciones oceánicas a continentales. Las evidencias térmicas, geológico-tectónicas y magnéticas han sido las bases para postular que existe una fuente de calor asociada a procesos magmáticos, similares a los que ocurren en un centro de dispersión típicamente oceánico. Con base en el estudio petrográfico y geoquímica de las rocas obtenidas durante la perforación de los pozos, se encontró que éstas se clasifican como basaltos, basalto-andesitas, andesitas y dacitas. El modelo petrogenético de los cuerpos volcánicos intrusivos que se propone para la zona de dispersión de corteza en el área de Cerro Prieto, difiere con el de un típico centro de dispersión oceánico, como es el caso de los centros de dispersión encontrados en el golfo de California. Se presenta el modelo típico de un centro de dispersión oceánico, como es el caso de los centros de dispersión encontrados en el golfo de California. Se presenta el modelo típico de un centro de dispersión oceánico y el modelo hipotético de dispersión para el área de Cerro Prieto. Esta región de magmatismo basáltico continental es compleja, lo cual se atribuye a: a) composición y mineralogía de la fuente en el manto, b) grado de fusión o mezcla parcial de magma primario, c) profundidad de segregación del magma y d) extensión de la cristalización fraccionada y los procesos de mezcla del magma durante el almacenamiento de éste en los niveles superiores de la cámara magmática.  Iniversidad Autónoma de Baja California1996-03-06info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Article Artículo Arbitradoapplication/pdfhttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/83210.7773/cm.v22i1.832Ciencias Marinas; Vol. 22 No. 1 (1996); 91-110Ciencias Marinas; Vol. 22 Núm. 1 (1996); 91-1102395-90530185-3880reponame:Ciencias Marinasinstname:UNIVERSIDAD AUTÓNOMA DE BAJA CALIFORNIAinstacron:UABCenghttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/832/756info:eu-repo/semantics/openAccessoai:cienciasmarinas.com.mx:article/8322024-08-22T17:01:35Z
