On the cover: Hand sample photographs of gold from Archean deposits in Ontario and Quebec, Canada, showing that gold occupies crosscutting features in the host quartz. (A) Croesus deposit (LM47273), Ontario. (B) Kerr Addison deposit (M38709), Ontario. (C) McIntyre deposit (M36549), Ontario. (D) O'Brien deposit (9919), Quebec. Photos were taken with the permission of the Ontario Geological Survey and the Royal Ontario Museum (ROM); the sample numbers refer to the ROM sample catalogue. The geology and ore deposits are described in the paper by Hastie et al. in this issue.
