Advances in understanding hydrogeologic units (HGUs) within fractured rock (e.g. Meyer et al. 2008) show that individual subdivisions can include several geologic layers and are largely controlled by mechanical responses to stresses that may or may not coincide with lithologic boundaries. Hydrogeologists have used temperature profiles for decades to characterize groundwater recharge and discharge at varying scales, however the vast majority of that work was focused on unconsolidated deposits. The basic premise of the approach, that variations in the thermal gradient are largely controlled by and therefore diagnostic of groundwater movement, is also applicable in fractured rock.
