Bouillante is a geothermal field on the west coast of Basse-Terre, Guadeloupe.
The deep geothermal reservoir at Bouillante is a mixture of seawater and meteoric water. The diluted seawater becomes depleted in Mg, SO4, Na, and enriched in Si, K, and Ca through interaction with host rocks, mainly andesite, at temperatures close to 250 deg C.
Eruptions in Pleistocene.
