News and CommentsThis week a mineral collector from eastern Europe sent photographs to me via email requesting identification of mineral species. When I responded that I could not identify the mineral species based solely on photographs, the collector went ballistic with the foulest curses against me and the entire geological community. So much for giving a courtesy reply to every inquiry... You cannot identify minerals based on photographs, unless it is a unique mineral with a rare habit that is not found in any other mineral, like sixling-twinned reticulated cerussite crystals. Before I pronounce an identification of species, I check ALL of these characteristics:
At the Rochester Mineralogical Symposium this year George Robinson, curator of the A.E. Seaman Museum at Michigan Tech lampooned over-reliance on microprobe and X-ray when he offered advice on identifying various minerals from the iron mining district of Michigan. He said he routinely uses his "electron microprobe streak plate" for determining some species, like differentitating between goethite and hematite. The foolishness of identifying minerals based on photographs can be found on the discussion boards of Mindat.org. Collectors submit photographs, then anyone with a keyboard submits their ideas of what the mineral species might be. One classic example was Glenn Rhein's find on his property in Warwick, New York in the Reading Prong geologic formation. Mindat contributors offered all kinds of proposals for identification of the species. Unfortunately few were aware of the mineralogy of the Reading Prong and many of their answers were far off the mark. Please do not email me photographs for identification. However, if you send me the descriptive characteristics of the seven attributes listed above AND you describe the geologic setting of the find, I will do my best to respond with identification.
