Using cave deposits as geologic tiltmeters: Application to postglacial rebound of the Sierra Nevada, California
[1] Secondary calcite shelfstone deposits in caves can be used to precisely measure tilting over geologic timescales. Calcite deposited along the edges of former pools can be surveyed to within a single millimeter, and can be dated using uranium-series disequilibrium. Two caves in the southern Sierr...
