Fluid-rock interaction and spatial-temporal reconstruction of hydrothermal systems

Aqueous fluids are important and widespread mass-transfer agents in the Earth’s crust and mantle, and large quantities of fluids are released from compacting sedimentary basins, metamorphic complexes, cooling magmabodies and degassing volcanic chambers. Large mobility of aqueous fluids induces disequilibrium interactions leading to formation of economic mineral deposits or used in artificial sequestration systems. However ,as fluids are generally not preserved in their pathways, the chemical and physical dynamics of hydrothermal systems must be reconstructed from alteration zoning in the rock record. We investigate natural case examples, develop multicomponent models of chemically reactive fluid flow and employ transport theory to reconstruct and classify hydrothermal systems based on their
spatial and temporal dynamics.
