Abstract
In the last few years, an increasing number of papers dealing with applications of cathodoluminescence (CL) imaging — using both optical microscopes (0M-CL) and systems operating with secondary electron microscopes (SEM) or electron microprobes (SEM-CL) — to investigate the internal structures of zircon have been published. CL has been demonstrated to be a powerful tool for investigating zircons. This method yields high-resolution images of internal structures that often cannot be detected with other techniques (e.g., HF etching, Normarski interference). In most previous publications, CL images were interpreted assuming that CL is exclusively generated within the micro-areas that are irradiated with the electron beam (e.g., Hanchar and Miller 1993; Vavra et al. 1996). We want to demonstrate here that this assumption may in several cases lead to some misinterpretation of the internal structure of zircon.
