EXPERIMENTAL STUDIES OF PLANETARY MAGMAS AT HIGH PRESSUREIT IS PROPOSED THAT THE CURRENT NASA GRANT "EXPERIMENTAL STUDIES OF PLANETARY MAGMAS AT HIGH PRESSURE" BE CONTINUED FOR A PERIOD OF THREE YEARS. THE PROPOSED CONTINUATION OF THIS WORK FOCUSES ON THREE MAIN TASKS: 1) PARTITIONING OF VOLATILE ELEMENTS BETWEEN MANTLE AND CORE 2) COMPRESSIBILITY OF HYDROUS AND CARBONATED IRON-RICH SILICATE LIQUID AND DENSITY CROSSOVERS IN VOLATILE-BEARING PLANETARY MANTLES 3) HIGH PRESSURE MELTING EXPERIMENTS CONSTRAINING MANTLE SOURCE REGIONS FOR MARTIAN BASALTS. ALL THREE TASKS WILL BE CARRIED OUT IN THE HIGH-PRESSURE AND ANALYTICAL LABORATORIES AT THE INSTITUTE OF METEORITICS UNIVERSITY OF NEW MEXICO. RESULTS FROM THESE STUDIES SHOULD ADVANCE OUR UNDERSTANDING OF THE DIFFERENTIATION AND THE ROLE VOLATILES IN THE EARTH MARS AND OTHER PLANETARY BODIES.
