Notable Impact of Paleotectonic Stress on Gold Mineralisation in the West Qinling Orogen
Geological Journal, EarlyView.By applying fuzzy clustering and multiple inverse methods, we systematically processed the data of vein and fault slip in this ore deposit to reveal the transition of orogenic geological environment and paleotectonic stress field. Our research results show two different stress states: the northwest–southeast extensional stress field and the northeast ...

From Implement to Outcrop: a model for identifying implement source rock at outcrop
Internet Archaeology, 2009 Traditionally, the sourcing of prehistoric stone tools in Britain has been done most successfully by comparing the petrological and geochemical characteristics of individual stone tools with rock and debitage from known prehistoric quarry sites and stone

Variable Sr Diffusion and Implications for Rb–Sr Biotite Geochronology
Journal 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
