OREAS C27d is a rhyodacite blank chip certified reference material (CRM). The material was sourced from a rhyodacitic unit of the Mt Dandenong Igneous Complex located approximately 34km east of Melbourne (Victoria), Australia. The CRM has a nominal particle size of minus 10mm to simulate RC drill chip samples.
