The rate at which ore deposits form is one of the least well established parameters in all of economic geology. However, increased detail in sampling, improved technology of dating, and sophistication in modeling are reducing the uncertainties and es

Pressure is the most important of the intensive parameters for relating epithermal mineralization to the geologic setting. This paper describes the limitations on pressure (and therefore depth) of mineralization that may reasonably be derived from si

The polybaric liquidus surface for the H2O-rich corner of the NaCl-CO2-H2O ternary is calculated, relying heavily on 1. (1) a Henry's law equation for CO2 in brines (modified from Drummond, 1981), 2. (2) the assumption that the contributions of disso

Over the past several decades, thinking about chemical processes in rocks had been dominated by experimental and theoretical treatments of mineral equilibrium, which is the state from which the time variable has been excluded. But, to an extent excee
The filling history, hydrologic budget, and geomorphic development of ancient Lake Creede and its tributary basin are evaluated to determine the factors that controlled its character. The lake filled the Creede caldera that formed in the late Oligoce

The heat capacity of CuFeS2 (chalcopyrite) was measured between 6.3 and 303.5 K. At 298.15 K, Cp,mo and Smo(T) are (95.67±0.14) J·K−1·mol−1 and (124.9±0.2) J·K−1·mol−1, respectively. From a consideration of the results of two sets of eq

Ore deposits form under a wide range of physical and chemical conditions, but those precipitating from hot, aqueous fluids—i.e. the hydrothermal deposits—form generally below 700°C and at pressures of only 1 or 2 kbar or less. Natural aqueous fl

The phase relations in the Fe-Sb-S system from 300 degrees to 800 degrees C have been determined using new experimental data on phase assemblages and univariant equilibria in conjunction with information from the literature. Estimates have been made
