From hydrothermal systems to mud volcanoes: structure, evolution and monitoring of active and fossile piercements

Submit an Abstract to this Session

Session ID#: 25911

Session Description:
Hydrothermal systems, mud volcanoes, sedimentary-hosted hydrothermal systems and piercement structures are usually characterized by deep-rooted plumbing systems and complex geochemical reactions where life can adapt to thrive in extremely harsh environments. Geophysical signals associated to such environments are often ambiguous and difficult to interpret. However, the elevated pore pressures often encountered at depth and the high flow rates make these environments ideal natural laboratories to investigate precursors of seismic events and dynamically triggered geological responses.

The session welcomes studies related to the: 1) investigation of such systems with geophysical methods; 2) geochemical reactions occurring at depth and at the surface including microbiological studies; 3) survey and the monitoring of these settings to learn the dynamics of the extinct systems from the active ones; 4) experimental and numerical studies; 5) study of palaeo piercements and their effects on palaeo-climates; 6) relation between the pre-existing geology and the emplacement of piercement structures.
