Pore water chemistry from mud volcanoes in the Olimpi Mud Volcano Field and Anaximander Mountains was studied to assess fluid transport modes and origins. Advective flow velocities were found to be moderate (3-50 cm y-1), and bioirrigation rates were 1-2 orders of magnitude higher. Calculated formation water temperatures range from 55-145 °C, suggesting fluid origins from deeper subsurface zones.
Use Cases
- Modeling upward advection and bioirrigation fluxes in surface sediments based on measured pore water profiles.
- Mapping spatial heterogeneity in fluid chemistry to infer discrete subsurface conduits and fluid origins.
- Predicting depth of fluid origin and geochemical reactions using theoretical geothermometers on calculated formation water temperatures.
- Investigating pore water freshening mechanisms linked to clay mineral dehydration at depth.
Strengths
- Includes specific, measured advective flow velocities (3-50 cm y-1).
- Provides calculated formation water temperature ranges (55-145 °C) for two distinct geographic areas.
- Profiles were successfully simulated by accounting for upward advection and bioirrigation, indicating a validated modeling approach.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
