Fluid Inclusion and Cathodoluminescence Laboratory
The FI/CL laboratory in the Department of Geology and Geological Engineering was established in 2008 through a generous donation by Chevron Corporation. The laboratory is used by students and faculty to study fluid inclusions and their textural settings.
The laboratory is equipped with an Olympus BX51 microscope for fluid inclusion petrography. Microthermometric data on fluid inclusions are collected using a Fluid Inc.-adapted U.S. Geological Survey gas-flow heating and freezing stage that is calibrated using synthetic fluid inclusions. Freezing temperatures measured on the system are accurate to 0.1°C. The accuracy of heating measurements ranges from approximately 2°C at 200°C to approximately 10°C at temperatures above 600°C. Imaging of fluid inclusion is conducted using an Optronics Microfire A/R camera. This camera also allows inspection of fluid inclusions using IR in selected opaque minerals (e.g. stibnite, enargite).
Hot-Cathode CL Microscope
The laboratory is equipped with a HC5-LM hot cathode CL microscope by Lumic Special Microscopes, Germany, which allows inspection of the thick sections under electron bombardment. The microscope was operated at 14 kV and with a current density of ca. 10 µA mm-2. CL images were captured using a high sensitivity, double-stage Peltier cooled Kappa DX40C CCD camera.
