221st ACS National Meeting: San Diego, CA(April 1-5, 2001)




Brief Description:

The development and application of new experimental techniques and procedures, supplemented by some rigorous theoretical modeling has provided new insights into several key organic and inorganic hydrothermal systems. With added interest towards the understanding of prebiotic chemistry, such studies have begin to provide valuable insight for physiochemical controls as well as the mechanics of key chemical processes.

Direct observation techniques of relevent organic and inorganic systems have added valuable information regarding reaction kinetics and pathways. Additionally, such studies have provided first hand information towards the formation of metastable and non-quenchable phases at high pressure and temperatures using in-situ techniques. This special session is offered with the aim of bringing together various theoretical and experimental techniques on a wide variety of chemical, biochemical and geochemical systems ranging from low to extreme conditions of temperature and pressure. Experimental studies addressing a wide variety of questions in organic and inorganic hydrothermal systems not restricted to phase-equilibria, mineral-fluid interaction and reaction kinetic studies in chemical and biochemical systems are invited to contribute to this special session. In addition to invited presentations, contributed papers are solicited that involve in-situ observations in discussing reaction pathways, catalytic reaction networks, molecular spectroscopic studies and hydrothermal geochemistry.
