Basse-Terre rivers without hydrothermal input (Guadeloupe)
Guadeloupe, Basse-Terre, France
Rivers and surface water
- Type
- River or surface water
Basse-Terre waters sampled from 2005 to 2007 around La Soufrière volcano (Louvat et al., 2011); Lesser Antilles arc lavas near 0 ‰ (+2 to +3 ‰ in Martinique, Smith et al., 1997). Coordinates not published. Dilute rivers (11 to 31 µg/L B); rain (δ11B near 45 ‰, Cl/B of 300) supplies 25 to 95 % of the boron.

| 42.5 ± 2 ‰ | 39.1 / 44.8 ‰ | 11 | river water (dissolved boron) Mean and standard deviation recalculated from 11 analyses, +39.1 to +44.8 (Goyaves 11/12/06 +44.4; Capesterre 09/11/06 +43.8; Capesterre 15/12/06 +40.1; Lézarde 11/12/06 +42.5; Lostau 04/12/06 +44.4; Grande Plaine 04/12/06 +39.1; Bras David 11/12/06 +44.8; Bras David 10/03/07 +43.7; Petite Plaine 04/12/06 +41.0; Petite Plaine 10/10/07 +42.6; Petite Plaine 12/10/07 +40.7). About 40 ‰ above the volcanic rocks: weathering fractionation (secondary minerals, adsorption onto clays, soil-vegetation cycle). Up to 4 ‰ difference between samples of the same river. | Louvat et al. (2011), Boron isotope ratios of surface waters in Guadeloupe, Lesser Antill… |
