Chapter 7. Checklist of Maine MineralsNumerous lists have been published which have attempted to inventory the mineral species found in Maine. The most important of these lists have appeared in the following publications, which are arranged in chronological order:
Each of the above mineral lists is longer or more specialized than its predecessors, and has included the progress of knowledge. The list that follows contains over 308 species that have been found in Maine. In addition, there are over 50 species whose occurrences in Maine do not appear to have been adequately studied, and at least three more that are new to science. The question marks call attention to reports on which further work should be done. Although an effort has been made to personally verify each entry, many mineral occurrences were copied directly from the above publications, as well as other sources. Most of the localities listed for each mineral species are names of towns or (in sparsely populated areas) unorganized townships such as Township D, T3 R5 BKP WKR, etc. Names of other geographic features and even a few rock formations are also included here, depending on the original sources of locality data. For example, a placer gold occurrence may be no more specific than the name of the river in which gold was found; and certain minerals listed in geological literature are widely distributed in rock formations that extend across town boundaries. Some reported localities may be difficult or impossible to find on a map. This is especially true of obsolete geographic names. A good reference that will pinpoint many of them is The Length and Breadth of Maine (Attwood, 1977). Modern towns, settlements, and civil divisions generally can be found in The Maine Atlas and Gazetteer. Only a few representative entries appear for the common species listed below, such as quartz, because there are many locations for these minerals. Other species are so rare in Maine that preserved examples are unknown. For example, pyrargyrite and proustite specimens from this state cannot be located in major mineral collections, and recent efforts to collect new samples have been unsuccessful. Some minerals have been found as loose specimens in glacial deposits, such as the axinite discovered in a single boulder in Wales. If an unconfirmed species is easily identified, and there is no evidence to discredit its reported Maine occurrence, we have included it in our checklist. The reputations of previous workers, who accepted identifications of specimens that were available during their eras, provide the basis for continuing a listing here. It is not the goal of producing a checklist to merely end up with a longer list than before. The primary requirement of this checklist is accuracy. It is as important to question previous discoveries as it is to report new ones. Collectors and professional mineralogists alike need to be careful in identifying what they have. There are a great many look-alike minerals. Their similarities frequently extend through the various tests to which a mineral can be subjected. A few species are so similar, that when they have been fully characterized, the choice of which name to give them is not much more than an opinion. Many of the question marks in this list probably refer to identifications made by individuals who jumped to erroneous conclusions. It may even be erroneous for us to question their identifications. It is essential to preserve rare minerals and provide as much data as possible when new discoveries are made. For example, spinel occurs in a variety of geological settings and is not a very rare mineral. Six of the ten Maine spinel localities listed here are from geologically reasonable environments, and have been confirmed with complete data or by analogy with scientific research elsewhere. However, the other four localities are doubtful, because of the chemistry of the host rocks and absence of conditions essential to the formation of spinel. The four questionable localities are also localities for the species gahnite, a poor synonym for which is "zinc spinel." Thus, a careless reference to a gahnite locality might simply read "spinel." An addition to any mineral checklist should be based on accurate identification of the sample, and the sample itself should be preserved. A good practice is to donate a specimen in its matrix to a curated public mineral collection. Samples without matrix are of less value because their mineralogical associations cannot readily be determined. The most up-to-date and conservative mineral nomenclature is used here, in conformity with accepted standards and decisions by the International Mineralogical Association (IMA). The Mineral Reference Manual by Nickel and Nichols (1991) is an essentially comprehensive account of all IMA-approved mineral names and formulas, including some variety names. The "=" designates modern, preferred, or interpreted equivalents of mineral names reported in the literature. acanthite(?) - Acton, Appleton, Cherryfield, Crawford, Deer Isle, Franklin, Gouldsboro, Hampden, Hancock, Hersey, Lubec, Newfield, Parmachenee (T5 R5 WBKP), Rockport, Sedgwick, Sullivan actinolite - Bethel, Blue Hill, Boothbay, Brunswick, Deer Isle, Freeport, Herman, Jay, Lewiston, Minot, Monmouth, Newry, North Haven, Oxford, Portland, Pownal, Raymond, Rockland, Rumford, Unity, Winthrop adularia = microcline;
