Provenance analysis of the Paparoa and Brunner Coal Measures using integrated SEM-cathodoluminescence and optical microscopy
International audience An integrated approach using grain-by-grain comparison of SEM-cathodoluminescence (CL) and petrographic characteristics was applied to investigate the provenance of fluvial/lacustrine quartz-rich lithic arenites deposited in the Late Cretaceous transtensional Paparoa Basin in...
