Ghislaine Crozaz (born 1939[1]) is a cosmochemist known for her research on the early history of the solar system through tracking trace elements in meteorites.
While a Ph.D. student, Crozaz pioneered the use of lead-210 to establish ages in ice cores in Antarctica[5][6] and Greenland.[7] While working in Brussels, Crozaz became interested in space science and meteorites she started working on the first lunar samples returned to Earth during the Apollo 11 mission.[8][4] She started her research in this arena by looking at fission tracks in lunar samples.[9] These lunar samples are still serving as the basis for scientific research many years later.[10][11] Crozaz went on to work with Ernest Zinner to develop an ion microprobe method to measure rare earth elements in the individual crystals found in extraterrestrial and terrestrial rocks.[12][13] Crozaz later participated in group efforts to sample meteorites in Antarctica, one of which was the first lunar sample found on Earth,[10] and through this research examined the history of meteorites found in Antarctica.[14][15]
