 | | Minerals other than feldspar and quartz that have been found in pegmatites in the map area include beryl, columbite, samarskite, allenite, uraninite (massive and small octahedral crystals), tourmaline, cleavelandite, apatite, dumortierite, chrysoberyl, rose quartz, garnet, cassiterite, cookeite, eosphorite, lepidolite, spodumene, zircon, torbernite, autinite, and uranophane (Thompson and others, 1991). |
 | | Morrill (1955) makes reference to iron mining and "emery" mining in Arrowsic, and apparently these openings (Figure 55 and Figure 56) were the prospects for iron ore (magnetite) and abrasive (garnet) which are abundant in the coticule. |
 | | Nor is there any mention of iron ore or emery mining in discussions of the results of the geological survey of the State of Maine during the late 1850's and earliest 1860's by Hitchcock (1861, 1862), or earlier by C. Jackson (1837, 1838, 1839). |
