Application of specific extraction chromatographic methods to the Rb-Sr, Sm-Nd isotope study of geological samples: The Hombreiro-Santa Eulalia Granite (Lugo, NW Spain)
The analytical application to geological samples of three new chromatographic resins, TRU-Spec ®, Sr-Spec ® and LN-Spec ®) has been investigated. Seven samples of the Hombreiro massif (Lugo, NW Spain) have been studied, that yield a Rb-Sr age of 298 ±5 Ma (SrQ = 0.7086, MSWD = 7.64) for the magma cr...

| Sumario: | The analytical application to geological samples of three new chromatographic resins, TRU-Spec ®, Sr-Spec ® and LN-Spec ®) has been investigated. Seven samples of the Hombreiro massif (Lugo, NW Spain) have been studied, that yield a Rb-Sr age of 298 ±5 Ma (SrQ = 0.7086, MSWD = 7.64) for the magma crystallization. Sm-Nd data results for the same massif give eNd values dose to -2 at 300 Ma. This suggests that the origin of the magma might be related to the partial melting of immature sediments, likely involving volcanoclastic sequences |
