Revealing the 3rd Dimension of Seafloor Hydrothermal Systems at Oceanic Plate Margins

Session ID#: 83677

Session Description:
Since the discovery of high-temperature hydrothermal vents on the seafloor more than four decades ago, it has become clear that the interplay between magmatism, tectonism, and hydrothermalism is highly variable. This has led to increased efforts to examine the subseafloor environment of hydrothermal systems in different geotectonic settings. This session will focus on new results (including IODP drilling, geophysical experiments, and chemical and microbiological investigations) that shed light on the internal structure of hydrothermal systems located along different types of oceanic plate margins. Studies may include volcanic architecture, permeability structure, fluid-rock interactions, seafloor mineralization, and the nature of the subsurface microbial community.
