In order to differentiate false trails from those produced by glacial grinding, it is recommended that the altered surfaces of garnets be examined under a scanning electron microscope.An analysis of chattermark trails on garnets from glaciogenic deposits from Nova Scotia, Denmark, and south-central Ontario shows that there is a wide variation in the percentage of garnets with chattermark trails in different glacial environments. However, after local anomalies in the percentage of Chattermarked garnets are averaged out by recycling and dispersion, there is evident a crude correlation between the type of glaciation and the average percentage of Chattermarked garnets in glacial deposits.
