ABSTRACT Securing a participant's voluntary, informed consent is widely acknowledged as a requirement of ethical research. Yet, challenges can arise, particularly when a researcher seeks to enroll older adults who may lack the capacity to consent to research participation due to cognitive impairment.

Variable Sr Diffusion and Implications for Rb–Sr Biotite Geochronology

open access: yesJournal of Metamorphic Geology, EarlyView.
ABSTRACT The rubidium–strontium (Rb–Sr) system has a long pedigree as a geochronological tool that relies on the application of an isochron approach. In particular, biotite contains strongly radiogenic Rb–Sr isotopes, and thus can yield meaningful crystallisation or cooling ages via this approach. However, the response of the Rb–Sr system in biotite to

Tracking Dehydration Reactions and Fossil Fluid Flux in Shear Zones Using Garnet Microstructures

open access: yesJournal of Metamorphic Geology, EarlyView.
ABSTRACT Shear zones act as preferential fluid pathways during prograde and retrograde stages of metamorphism. Nonetheless, we still have limited knowledge of the drainage and permeability of natural settings. The preserved signature of fluid in exhumed rocks provides insights into fluid flow during burial and exhumation.
