Calculation of individual isotope equilibrium constants for implementation in geochemical models
Donald C. Thorstenson, David L. Parkhurst
2002, Water-Resources Investigations Report 2002-4172
Theory is derived from the work of Urey to calculate equilibrium constants commonly used in geochemical equilibrium and reaction-transport models for reactions of individual isotopic species. Urey showed that equilibrium constants of isotope exchange reactions for molecules that contain two or more atoms of the same element in equivalent positions...
Comparison of formation and fluid-column logs in a heterogeneous basalt aquifer

2002, Groundwater (40) 577-585
Deep observation boreholes in the vicinity of active production wells in Honolulu, Hawaii, exhibit the anomalous condition that fluid-column electrical conductivity logs and apparent profiles of pore-water electrical conductivity derived from induction conductivity logs are nearly identical if a formation factor of 12.5 is assumed. This condition is documented in...
