New approach to the radiocarbon dating of rock varnish, with examples from drylands

Abstract

New electron microscope observations reveal that organic inclusions are often trapped in pockets onder rock varnish. Accelerator radiocarbon dating of subvarnish organic detritus provides a new method of constraining when a rock was exposed by cultural or geomorphic processes. Applications are exemplified for human artifacts and landforms found in drylands (South Australia, Peru, Colorado River, Mojave Desert in California)
