Abstract

ABSTRACT Raman spectroscopy is used for the first time for distinguishing igneous zircons from metamorphic zircons. Igneous zircons, especially those from granitic rocks, commonly show a Raman peak at 1461 Δcm−1 with significant intensity, whereas metamorphic zircons do not show this peak or the peak is very weak. This may be related to the rare‐earth element (REE) contents in zircon. Thus, Raman spectroscopy provides a new, fast and non‐destructive means for investigating the structure and origin of zircons.
