Professor Nekvasil's research focuses on the effects of magmas and the fluids that they produce on planetary crust evolution. Her group’s research combines analytical studies of meteorites and returned samples with experimental simulations of processes ranging from igneous fractionation, to high temperature metamorphism, and fluid/rock interactions.
Lunar studies Our recent lunar studies have focused on the mineral apatite and have shown for the first time that lunar magmas may have contained significantly more water than previously thought. Ongoing investigations involve experimental simulations of processes that can affect apatite composition such as magmatic degassing, and analytical studies of lunar meteorites and Apollo samples in order to provide new insights into the composition of the lunar interior.
Martian studies Our martian studies use analytical investigations of martian meteorites and lander and orbiter data to develop experimental investigations focused on constraining the nature of martian magmas and the fluids that have exsolved from them, the development of igneous stratigraphy of the martian crust, and interaction of magmatic fluids with the martian crust and the formation of hydrothermal alteration assemblages.
