Fluid Inclusion and CL 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.

Fluid-Inclusion Microscope

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).

CL MicroscopeHot-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.
