Liquid-vapor interface of a polydisperse fluid.

We report a grand canonical Monte Carlo simulation study of the liquid-vapor interface of a model fluid exhibiting polydispersity in terms of the particle size sigma. The bulk density distribution, rho0(sigma), of the system is controlled by the imposed chemical potential distribution mu(sigma), the form of which is specified such that rho0(sigma) assumes a Schulz form with associated degree of...

Changing moisture sources over the last 330,000 years in Northern Oman from fluid-inclusion evidence in speleothems

Speleothems from Hoti Cave in northern Oman provide a record of continental pluvial periods over the last 330,000 yr. Periods of rapid speleothem deposition occurred from 6000 to 10,500, 78,000 to 82,000, 120,000 to 135,000, 180,000 to 200,000, and 300,000 to 330,000 yr ago, with little or no growth during the intervening periods. During each of these five pluvial periods, D values of water ext...

Liquid-vapor phase behavior of a symmetrical binary fluid mixture

Using Monte Carlo simulation and mean-field calculations, we study the liquid-vapor phase diagram of a square-well binary fluid mixture as a function of a parameter d measuring the relative strength of interactions between particles of dissimilar and similar species. The results reveal a rich variety of liquid-vapor coexistence behaviors as d is tuned. Specifically, we uncover critical end poin...

The Fluid Inclusion And Mineralogic Record Of The Transition From Liquid- To Vapor-Dominated Conditions In The Geysers Geothermal System, California

Fluid-inclusion measurements and textural relationships demonstrate that coarse-grained quartz and calcite from the upper part of The Geysers thermal system formed during the transition from liquid-dominated conditions to the modern vapor-dominated regime. The most diagnostic characteristics of these transition assemblages are: 1) evidence of quartz dissolution; 2) contemporaneous trapping of h...

Martian surface paleotemperatures from thermochronology of meteorites.

The temporal evolution of past martian surface temperatures is poorly known. We used thermochronology and published noble gas and petrographic data to constrain the temperature histories of the nakhlites and martian meteorite ALH84001. We found that the nakhlites have not been heated to more than 350 degrees C since they formed. Our calculations also suggest that for most of the past 4 billion ...
