Hydrothermal chlorite

Web1 mei 2015 · The biotite chloritization involves two essential formation mechanisms: chlorite formation (CF) mechanism 1, small volume decrease from biotite to chlorite and large inflow of metallic ions such as Al 3+ , Fe 2+ , Mn 2+ , and Mg 2+ from the hydrothermal fluid, and CF mechanism 2, large volume decrease and large outflow of the metallic ions into ... WebOur results imply that chlorite-rich faults under hydrothermal conditions in a subduction zone are frictionally weak, possibly providing pathways for dynamic megathrust fault ruptures to propagate. Chlorite fault rocks are predominantly nonseismogenic under greenschist facies conditions, except around 300 °C, corresponding to ~15-km depth for …
