Abstract
[Resumen] En este trabajo se estudian y describen las particularidades mineralógicas, petrograficas y químicas encaminadas a la correcta caracterización y clasificación del "pasillo de enclaves" de Cangas de Morrazo - Moaña (Ria de Vigo). Desde el punto de vista petrografico y químico aparecen tres tipos diferentes de enclaves asociados a rocas básicas y granitos biotíticos, todas ellas emplazadas en las denominadas granodioritas precoces de Galicia. Los enclaves son fundamentalmente rocas tonalíticas y granodioríticas cuyas diferencias esenciales parecen estribar en un grado de hibridación progresivo entre magma ácido y magma básico
[Abstract] This paper deals with the petrographical and geochemical characteristics of the enclaves situated near the estuary of Vigo, between the localities of Cangas de Morrazo and Moaña (Pontevedra, NW of Spain). Enclaves are associated to basic rocks and al1 of them are placed into older hercynian granodiorites of Galicia. There are essentially three types of enclaves ranging from tonalites to granodiorites The difference-between them can be explained by the progressive grade of basic and acid magma hybridation
