The rock samples could be divided into two main groups. The first group (5 samples), located to the north of the Azuero-Soná Fault, strikes at 70° NE and is characterized by plagioclase laths, augite crystals and chlorite alteration in an ophitic to poikilitic texture, the geochemical results corresponds to flat REE patterns and calc-alkaline signatures, the trace element data suggest an oceanic island arc. These results suggest that these rocks correspond to the protoarc sequence, that occurred as the early stages of transition from plume to arc magmatism. The second dyke group (6 samples), strikes at 25° NE and is characterized by plagioclase and pyroxene in poikilitic texture, with interstitial and amygdular zeolites. The REE pattern correspond to an OIB signature, the trace elements indicate intraplate volcanism. This intrusion is related to a post seamount accretion against the Caribbean plate margin, when the rollback of the subduction slab occurred and provided new space for dykes to intrude the enriched seamounts. These results together with field data is compared with previous studies to propose a new tectonostratigraphic evolution of the peninsulaGeocientíficoPregrado36 hojasapplication/pdfengUniandesGeocienciasFacultad de CienciasDepartamento de Geocienciasinstname:Universidad de los Andesreponame:Repositorio Institucional SénecaGeochemical and petrological characterization of basaltic dykes in the Azuero Peninsula (Panama) - implications and tectonostratigraphic evolutionTrabajo de grado - Pregradoinfo:eu-repo/semantics/bachelorThesishttp://purl.org/coar/resource_type/c_7a1fhttp://purl.org/coar/version/c_970fb48d4fbd8a85Texthttp://purl.org/redcol/resource_type/TPPetrología - Investigaciones - Península de Azuero (Panamá)Estratigrafía - Investigaciones - Península de Azuero (Panamá)Geomorfología - Investigaciones - Península de Azuero (Panamá)Geotectónica - Investigaciones - Península de Azuero (Panamá)GeocienciasPublicationhttps://scholar.google.es/citations?user=ikmh8i0AAAAJvirtual::8191-10000-0002-8247-4116virtual::8191-1https://scienti.minciencias.gov.co/cvlac/visualizador/generarCurriculoCv.do?cod_rh=0000406740virtual::8191-1a782b64a-d94d-4fd1-b866-03e18a0b504fvirtual::8191-1a782b64a-d94d-4fd1-b866-03e18a0b504fvirtual::8191-1TEXTu729716.pdf.txtu729716.pdf.txtExtracted texttext/plain57386https://repositorio.uniandes.edu.co/bitstreams/1f0927bf-c559-473e-bc4a-c92b5724b592/download6d23af4ce576df05200fc3696587a1e3MD54ORIGINALu729716.pdfapplication/pdf3309770https://repositorio.uniandes.edu.co/bitstreams/d137225c-8b09-459b-a298-09277836e7b1/download33ae6bd093460708b5b9dc222f95425aMD51THUMBNAILu729716.pdf.jpgu729716.pdf.jpgIM Thumbnailimage/jpeg7885https://repositorio.uniandes.edu.co/bitstreams/6c9d8e47-5c19-46b3-8aa4-37a7c2d92098/download1615f5415a165607be560aeae0232998MD551992/18125oai:repositorio.uniandes.edu.co:1992/181252024-03-13 13:37:05.024http://creativecommons.org/licenses/by-nc-sa/4.0/open.accesshttps://repositorio.uniandes.edu.coRepositorio institucional Sénecaadminrepositorio@uniandes.edu.co
