Research Abstract

New method for determining the chemical composition of fluid and melt under high pressure and high temperature conditions has been developed using laser induced breakdown spectroscopy. Also, the second critical endpoints in the systems peridotite-H2O (±CO2) and basalt-H2O have been investigated using high pressure and high temperature x-ray radiography.
