The system CaO-MgO-SiO2-CO2-H20 is an important model for many igneous and metamorphic processes, including the generation and differentiation of carbonatite and associated silicate magmas. We have experimentally established the vapor-saturated solidus for the system CaO-MgO-CO2-H20 from 595øC/1 kbar to <500øC/40 kbar, about 25øC lower than the corresponding temperatures for the CaOCO•-H•O syst...

Recent studies have pointed to olfactory system beta oscillations of the local field potential (15-30 Hz) and their roles both in learning and as specific responses to predator odors. To describe odorant physical properties, resultant behavioral responses and changes in the central olfactory system that may induce these oscillations without associative learning, we tested rats with 26 monomolec...
