Abstract

A new system is described that permits real-time microdrilling of sedimentary grains and crystals within cathodoluminescence zonations. Low-light cathodoluminescence photomicrograph images are captured with a thermoelectrically cooled color video camera and saved on a computer. These cathodoluminescence images are then transparently superimposed on a standard color video image of the sample being microdrilled on a 20 μm scale using a video mixer. This integrated system can be applied to a wide variety of sedimentary rocks and minerals.
