An analysis of the cooling of intrusives by ground-water convection which includes boiling

The Distribution and Timing of Molybdenite Mineralization at the El Teniente Cu-Mo Porphyry Deposit, Chile

“…These age ranges are also in accordance with previous studies which concluded that the emplacement of an intrusion and the subsequent focusing of large fluid fluxes through it is likely to occur on a time scale of 10,000 to 100,000 years (Cathles, 1977(Cathles, , 2000Driesner and Geiger, 2007;von Quadt et al, 2011). Molybdenite Re-Os dates within and proximal to the Southern and Central Diorites cluster between 5.4 and 5.3 Ma and correlate well with crystallization ages for the Central Diorite (Maksaev et al, 2004).…”

Volcanogenic uranium deposits: Geology, geochemical processes, and criteria for resource assessment

“…Convection is known to have important chemical consequences in epithermal ore and geothermal systems (Cathles, 1977;Henley and Ellis, 1983;Hayba, 1997) and needs to be considered in volcanogenic uranium deposit models. Examples are shown in figures 15, 16, and 17.…”

“…Boiling also causes rapid cooling (Cathles, 1977;Cunningham and others, 1998) and mineral precipitation. Effervescence of CO 2 is similar to boiling and was described as the key to U deposition at the Schwartzwalder uranium deposit (Wallace and Whelan, 1986).…”

Modeling of thermodynamic and chemical changes in low-temperature geothermal systems

“…These simulators have been used to model the behavior of two-phase and vapor dominated fields (eg. Moench, 1976) as well as to predict the convective heat tran$fer near plutons (KaDg and Ahern, 1984;Cathles 1977;Norton and Knight, 1911). These wil.l not be reviewed in detail, as the present work is mostly interested with single-phase systems.…”
