Source volume: 54, issue: 1, PDF page: 107. Label: Figure 43. Copper “pipe amygdules,” 12 cm, from the Ashbed flow. Several mines had workings in the Ashbed flow, so although this specimen is most likely from the Copper Falls mine, it could also be from the Arnold or even the Phoenix mine. See the geology section of this article for the details on how these odd specimens form. Ex Cranbrook and Robert Rann collections. A. E. Seaman Mineral Museum collection; John Jaszczak photo.
