Congratulations to Jie Cheng for finishing her Honours thesis! Jie produced a stratigraphic cross section of Milne Lake, South Australia using quantitative mineralogical and crystal chemical data. Milne Lake is a rare lake that precipitates Holocene magnesite and very high magnesium calcite (“disordered dolomite”). Jie will be starting a Master’s degree in Earth and Environmental Engineering at Columbia University this fall. Congratulations Jie!
