Certain heavy minerals enriched in yttrium, such as monazite and xenotime, have previously been indexed in the Vigo area. The levels and spatial distribution of this element were studied in 50 surface sediment samples from the Vigo Ria. The highest levels were found along the southern margin in the...

| description | Certain heavy minerals enriched in yttrium, such as monazite and xenotime, have previously been indexed in the Vigo area. The levels and spatial distribution of this element were studied in 50 surface sediment samples from the Vigo Ria. The highest levels were found along the southern margin in the middle of the ria, coinciding with the geological source of the Galiñeiro Complex. From this zone, a dilution of yttrium in the sediments was observed seaward due to the presence of calcium carbonate (outer ria) and upstream due to the input of migmatites, anatexites, and two-mica granites (inner ria). The estimated background concentration in the Vigo Ria was 14.6 ± 2.6 mg kg–1 (Sc normalized), which is close to the average concentration found in surface sediments (13.4 ± 5.4 mg kg–1). This suggests that yttrium in the Vigo Ria sediments is mainly of lithogenic origin.
Con base en el registro de minerales pesados ricos en itrio tales como la monacita y la xenotima en el área de Vigo, se midieron los contenidos y la distribución de este elemento en 50 muestras de sedimento superficial de la ría de Vigo. Se encontraron los valores más altos en el margen sur de la mitad de la ría, lo cual coincide con una característica geológica procedente del Complejo del Galiñeiro. Se observó, a partir de esta zona, una dilución de itrio debida a la presencia de carbonato de calcio en la parte externa de la ría y además por la entrada de migmatitas, anatemitas y granitos de dos micas en la parte interna de la ría. El valor de fondo medio calculado para la ría de Vigo fue de 14.6 ± 2.6 mg kg–1 (normalizado con Sc) el cual es cercano a la concentración media estimada en los sedimentos superficiales 13.4 ± 5.4 mg kg–1. El origen de itrio en la ría de Vigo es principalmente litogénico. |
