文摘

Displacement of preserved pore water from claystones by imposing a hydraulic gradient with an artificial pore water yields early extracts characteristic of the pore water. Long-term tracer breakthrough behavior provides transport properties and anion-accessible porosity, whereas elution of major components are controlled by ion exchange and mineral solubility. A single long-term experiment provides a comprehensive system understanding.
