Structure and distribution of cold seep communities along the Peruvian active margin: relationship to geological and fluid patterns
摘要：
Exploration of the northern Peruvian subduction zone with the French submersible Nautile has revealed benthic communities dominated by new species of vesicomyid bivalves (Calyptogena spp. andVesicomya sp.) sustained by methane-rich fluid expulsion all along the continental margin, between depths of 5140 and 2630 m. At large scale, the communities are associated with fluid expulsion along the major tectonic features (scarps, canyons) of the margin. At a smaller scale on the scarps, the distribution of the communities appears to be controlled by fluid expulsion along local fracturation features such as joints, faults and small-scale scars.
