Cathodoluminescence and its Application to Geoscience

Cathodoluminescence and its Application to Geoscience

Topics in Mineral Sciences Volume 45

Editor: I.M. Coulson

This short course volume addresses both the theory behind the phenomenon of cathodoluminescence (CL) and the application of this microscopic technique to all fields of geoscience investigation.

Aimed at the graduate student, researcher and practicing professional, short course chapters will cover the basics of theory, causes of cathodoluminescence in minerals and materials, instrumentation, recent advances in cathodoluminescence imaging and spectroscopy data collection, and interpretation of spectral responses.

Case studies relating to sedimentological, petrological, mineralogical, petroleum geology and economic geology fields are included.

Description

Cathodoluminescence microanalysis is a versatile technique for studying optical excitation processes that occur in many minerals. The value of CL microscopy and spectroscopy to geological enquiry lies in its power to address fundamental questions of mineral growth, cementation, replacement, deformation, and provenance. In particular, some questions that can be addressed through the application of CL methods include the identification of domains within zircon- features critical to interpreting U-Pb geochronological data of ancient rocks, or in deciphering multiple episodes of cementation as a result of diagenesis during burial of sandstone that may host hydrocarbons. Moreover, the extreme sensitivity of CL to minute changes in composition or structure within minerals allows this technique to reveal fine-scale features not resolvable in samples studied by other methods, such as optical microscopy.
