GEOLOGY


Sarah is a second year Master's student at NMHU and is conducting a multi-disciplinary magma emplacement study of two, Oligocene and Miocene age, silica-undersaturated diatremes in the Eger Rift, Czech Republic. The goal of her thesis is to understand how how varying degrees of alkaline magma generation, triggered by a dynamic continental rift stress regime yielded unique emplacement mechanisms of the Eger Rift volcanic systems. She is currently mapping both quarries, and is conducting comprehensive petrographic analysis of both systems, a full geophysics analysis (anisotropy of magnetic susceptibility, paleomagnetics, rock magnetic experiments, and ground magnetometry), and 40Ar/39Ar geochronology.
