Notes on Vent Field Description:
Medanos de Punta Banda (intertidal), Bahia Papalote (subtidal); Vidal et al. (1978): "hydrothermal activity occurs within the Agua Bianca Fault"; subaerial expression is Punta Banda Geothermal Field; Vidal et al. (1981): "The PBSHS water is a primary high temperature, acid, reducing fluid of old seawater origin which has been titrated by cold, alkaline groundwater of meteoric origin. ... In contrast, the subaerial hot spring waters are of unmixed meteoric origin."; not related to active volcanism
