Caracteres petrológicos y estructurales del Paleozóico de las sierras de Vicort y Algairén

Abstract

[ES] Las Sierras de Vicort y Algairén, situadas en la Cordillera Ibérica', en la provincia de Zaragoza, están constituidas fundamentalmente por materiales paleozoicos (Precámbrico-Silúrico Superior). Los rasgos tectónicos estudiados muestran ser los generales de toda la Cordillera, con superposición de características hercínicas y alpinas, habiéndose identificado pliegues P1 {N30-N45), P2 (N120~N135) con esquistosidades asociadas S1 y S2' y lineaciones 11, 12 Y 1'2' La litología del área corresponde a materiales samíticos (cuarcitas, grauwacas y arenitas s.l.), pelíticos (limolitas y argilitas) y carbonáticos (calizas y dolomías) que han alcanzado las condiciones de la anquizona, mostrando tal grado de transformación que imposibilita la identificación de la composición mineralógica sinsedimentaria.

[EN] The Sierras Vicort and Algairen fram Ibelian Rangc are situated in Zaragoza province and are constituted by paleozoic materials (Precambrian-Silurian). StructuraI features are dues to Hercynian and Alpine orogenies superposition and we have identified folds, slaty cleavages and lineations accord to general Iberian Range characteristics. The petralogic analysis for samitic, pelitic and carbonatic rocks, permit to identlfy anchimetamorphic conditions what have oblitered smsedimentary mincralogic composition.
