Species: SAMARSKITE-Y Locality: Ham-Weeks Mine, Wakefield, NH Specimen Size: 4.5 cm specimen with central zone of black columbite. Samarskite-Y is 1 to 2 mm thick resonous-brown zone on right edge of columbite, (yellow arrow). Field Collected: Gene Bearss - 1979 Catalog No.: 1742 Notes: Samarskite-Y verified by EDS analysis. |

Species: DOLOMITE Locality: Livermore Falls, Campton, NH Specimen Size: 7 mm field of view. Milky rhombs of dolomite on quartz to 0.4 mm. Field Collected: Tom Mortimer Catalog No.: u1118 Notes: Dolomite, CaMg(CO3)2 , indicated by EDS analysis. Low element weight Mg peak somewhat attenuated by EDS detector compared to Fe peak. This would likely be ferroan dolomite, bordering on ankerite. |

Species: SCORZALITE - (previously labeled as LAZULITE) Locality: Jackson Hill, Stoddard, NH Specimen Size: 3 cm zone of massive scorzalite with muscovite mica Field Collected: A Harvard Mineral Museum specimen Catalog No.: #100715 Labeled as Lazulite Notes: A Feb., 2011 EDS analysis of a grain from this specimen showed an absence of magnesium indicating this phosphate species is scorzalite, Fe2+Al2(PO4)2(OH)2 , not lazulite, (Mg,Fe2+)Al2(PO4)2(OH)2 . Specimen photo moved to scorzalite gallery. |

Species: ALMANDINE-QUARTZ - (previously labeled as RHODONITE) Locality: Rt 112 road cut, Easton, NH Specimen Size: 3 cm specimen with massive pink almandine - quartz vein. Field Collected: Tom Mortimer Catalog No.: 1642 Notes: A Feb., 2011 EDS analysis of a grain from this specimen showed a minimal amount of manganese. The EDS analyst concluded "This is a quartz matrix which is shot with millions of tiny blebs of an almandine garnet." |
|
Species: RHODONITE Locality: Wildwood, Easton, NH Specimen Size: 3.2 cm specimen with zone of massive pink rhodonite. Field Collected: Bob Whitmore Catalog No.: 1779 Notes: Hardness greater than 5, not soluable in HCl, therefore not rhodochrosite. |
|
Species: VESUVIANITE on Grossular Locality: Joppa Hill, Amherst, NH Specimen Size: 0.8 cm double terminated vesuvianite crystal on 1.8 cm grossular garnet with minor pale green diopside. Field Collected: Bob Janules Catalog No.: Notes: |

Species: VESUVIANITE on Grossular - another view Locality: Joppa Hill, Amherst, NH Specimen Size: 0.8 cm double terminated vesuvianite crystal on 1.8 cm grossular garnet with minor pale green diopside. Field Collected: Bob Janules Catalog No.: Notes: |

Species: MORAESITE Locality: Chickering Mine, Walpole, NH Specimen Size: 5 mm field of view. Radial sprays of moraesite Field Collected: Tom Mortimer Catalog No.: Notes: Moraesite, Be2[OH|PO4] · 4H2O, confirmed by EDS analysis. Note, elements lighter than sodium (i.e. Be and O) do not generate a response on the EDS detector. |
