“…5, 6 and 7). The high Zn concentrations of up to 218 nM, which exceed the concentrations of all the other metals measured, agree with high Zn concentrations compared to ambient seawater measured in the region around Guadeloupe by Polyak et al (1992). High Zn concentrations of up to 3.1 μM where also reported for fluids from vent sites in back-arc areas, when compared to MOR fluids (maximum 0.78 μM, see compilation of von Damm, 1995).…”

Subduction of Atlantic seafloor under the Caribbean plate causes shallow earthquakes within the Lesser Antilles volcanic arc. Such earthquakes, above the subduction interface, show strike‐slip or normal fault plane solutions, the latter with ∼E‐W striking nodal planes. To better assess seismic hazard and the coupling between volcanism and tectonics, we investigated faulting related to overriding‐plate deformation in the Guadeloupe archipelago. Using aerial photographs, satellite SPOT images, and topographic maps (1/25000 scale), we mapped active and middle to late Pleistocene fissures and normal fault systems that cut the uplifted coral platforms Grande‐Terre and Marie‐Galante and the volcanic rocks of Basse‐Terre. The available marine geophysical data show that the faults extend offshore to bound submarine rifts. The E‐W striking, 1500 m deep, V‐shaped Marie‐Galante rift separates the two islands of Marie‐Galante and Grande‐Terre. Normal faults in the north of Grande‐Terre appear to mark the similarly V‐shaped, western termination of the 5000 m deep, N°50E to N130°E striking Desirade graben. Three shallow, M ∼ 5.5 earthquakes (6 May 1851, 29 April 1897, 3 August 1992) appear to have ruptured segments of the Marie‐Galante rift boundary faults. The young “La Grande Découverte” volcanic complex of Basse‐Terre, including the 1440 A.D. Soufrière dome, lies within the western termination of the Marie‐Galante rift. The ancient volcanic shoulders of the rift buttress the active dome to the north and south, which may explain why major prehistoric sector collapses and pyroclastic avalanches have been directed southwestward into the Caribbean Sea, or southeastward into the Atlantic Ocean. The Marie‐Galante rift is typical of other troughs transverse to the northeastern edge of the Caribbean plate. We interpret such troughs, which are roughly orthogonal to the arc, to result from slip‐partitioning and extension perpendicular to plate convergence. That they disappear southward implies that they result from interaction between the Caribbean and North American plates.

“…However, evidence of submarine hydrothermal activity had been reported northwest of Guadeloupe (Polyak et al, 1992). The work described in the present article has shown that several of the volcanic islands of the Lesser Antilles, St. Lucia, Dominica, St. Kitts, and Montserrat, have oOE shore hot springs which are fed by seawater dominated hydrothermal¯uid heated by magmatic activity beneath the volcanoes.…”

Hydrothermal Metalliferous Sediments and Waters Off the Lesser Antilles

Considerable metal enrichments have been found in hydrothermalXuids and metalliferous sediments oV the central Lesser Antilles Volcanic Arc. The elements variably enriched in the Xuids as a result of the hydrothermal activity are Fe, Mn, As, Si, B, Li and in the sediments, Fe, P, Mo, As, Sb, Hg, Cu and Pb. Variations in the concentrations of these elements in both Xuids and sediments along the arc result from a number of factors, the most important of which is the stage that each island's volcano has reached in its eruptive cycle. Although hydrothermal mineralization on the seaXoor oV the islands is only low grade, phase separation in the hydrothermal Xuids at depth could be leading to higher grade stockwork mineralization below the vent Welds or the discharge of metal rich brines on the lower Xanks of the volcanic islands.
