Este cuerpo desarrolla metamorfsmo de bajo grado en la facies esquisto verde sin obliterar la textura original de la roca. La composición de las rocas del Metagabro del Ariari indican una afnidad toleítica (gabros; SiO2= 46,93 -47,69 wt%, FeO +MgO = 18,42 -19,13 wt% y K2O+Na2O= 4,16 -10,42wt%), relaciones Nb/Y = 0,13-0,17 con patrones de REE caracterizados por LREE ligeramente empobrecidos y patrones menos fraccionados y relativamente planos de tierras raras pesadas (HREE). La composición en elementos traza muestra patrones fraccionados en los LILE, con enriquecimientos en Cs, Ba y Rb y una ligera anomalía negativa en Pb. Todas las características sugieren, por tanto, que el Metagabro del Ariari se formó en un ambiente de fondo oceánico (MORB). application/pdftext/htmlspaUniversidad Industrial de Santanderhttps://revistas.uis.edu.co/index.php/revistaboletindegeologia/article/view/4472/4742https://revistas.uis.edu.co/index.php/revistaboletindegeologia/article/view/4472/5257Boletín de Geología; Vol. 36 Núm. 2 (2014): Boletín de GeologíaBoletín de Geología; Vol. 36 No. 2 (2014): Boletín de GeologíaBOLETÍN DE GEOLOGÍA; v. 36 n. 2 (2014): Boletín de Geología2145-85530120-0283Ariari MetagabbroPetrographyMORBEastern CordilleraMetagabro del AriariPetrografíaMORBCordillera OrientalMETAGABRO DEL ARIARI, PLUTONISMO MORB, CORDILLERA ORIENTAL DE COLOMBIAARIARI METAGABBRO, MORB PLUTONISM, EASTERN CORDILLERA OF COLOMBIAinfo:eu-repo/semantics/articlehttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_2df8fbb1Toro-Toro, Luz MaryMoreno-Sánchez, MarioGómez-Cruz, Arley20.500.14071/5233oai:noesis.uis.edu.co:20.500.14071/52332022-03-16 12:39:35.365metadata.onlyhttps://noesis.uis.edu.coDSpace at UISnoesis@uis.edu.co |

Petrographic and geochemical characteristics from Ariari Metagabbro are shown in this paper. The Metagabbro outcrops at La Crystalline creek located eastwards from of El Dorado town, department of Meta in the Eastern Cordillera. This body develops low-grade metamorphism in the green schist facies, but not obliterated the original texture of the rock. The chemical composition of Ariari metagabbro indicates a tholeiitic affnity (gabbros; SiO2= 47.69 - 46.93 wt%, FeO + MgO = 18.42 -19.13 wt% and K2O + Na2O = 4.16-10.42wt %) Nb/Y ratios = 0.13-0.17 with REE patterns characterized by slightly impoverished LREE and less fractionated patterns and relatively fat HREE. The trace element composition shows fractionated LILE patterns, with Cs, Ba and Rb enrichments and a slight negative Pb anomaly. These features suggest that the Ariari Metagabbro was originated in a MORB setting. |
