Species: ANORTHITE Locality: Piper-Whiteface Trail, west side Piper Mtn., Gilford, NH Specimen Size: 5 cm specimen. Anorthite crystals in diabase matrix Field Collected: Tom Mortimer (Oct., 2010) Catalog No.: Notes: |

Species: FLUORITE Locality: Stoddard Mine, Westmoreland, NH Specimen Size: 2.5 cm specimen with 1.1 cm clear fluorite octahedron, with secondary cubic-octahedral overgrowth. Field Collected: Tom Mortimer Catalog No.: 1068 Notes: |

Species: FLUORITE Locality: Knox Mtn., Ossipee, NH Specimen Size: 9 cm specimen. 1 cm fluorite cube on microcline. Field Collected: Mike Graham Catalog No.: 1362 Notes: |

Species: CHILDRENITE-EOSPHORITE Locality: Chickering Mine, Walpole, NH Specimen Size: 3 mm lustrous radial spray of clear childrenite-eosphorite crystals on siderite matrix. Field Collected: Peter Cristofono (2010) Catalog No.: Notes: The EDS analysis of this specimen showed that it is slightly on the Childrenite side of the childrenite-eosphorite series. The manganese content must be grater than the iron content for the specimen to fall on the eosphorite side of the childrenite-eosphorite series. The analysis of several Chickering Mine childrenite-eosphorite specimens has yet to yield a sample that falls on the eosphorite side of the series. This was the first clear example that was analyzed. The previously analyzed ones were pale yellow. |

Species: WARDITE Locality: Chickering Mine, Walpole, NH Specimen Size: 1 mm wardite crystal with iron staining Field Collected: Tom Mortimer Catalog No.: u782 Notes: |

Species: FERROHORNBLENDE Locality: Streambed, Streeter Hill, Chesterfield, NH Specimen Size: 15 cm specimen. Black sprays of ferrohornblende in fine-grain mica matrix with garnets. Field Collected: Tom Mortimer (2008) Catalog No.: Notes: Ferrohornblende indicated by EDS analysis. An interesting water-worn/glacially-polished rock. |

Species: MUSCOVITE Locality: Keyes Mine #1, Orange, NH Specimen Size: 9 cm specimen with 1.8 cm muscovite crystal in large albite vug. Field Collected: Tom Mortimer Catalog No.: Notes: Several small blue-green apatite crystals are also visible. |
|
Species: GEDRITE Locality: West side Surry Mtn. Surry, NH Specimen Size: 10 cm specimen with 3 cm gedrite crystal spray in quartz. Field Collected: Tom Mortimer Catalog No.: Notes: Reference gedrite data page that relates to this locality. |

Species: FORSTERITE - Fe rich (Olivine) Locality: Everett Lake, Dike 2 rip-rap, Hopkington, NH Specimen Size: 5 cm specimen with glassy green olivine blebs and glassy black augite embedded in basalt. Field Collected: Tom Mortimer (Sept. 2007) Catalog No.: Notes: Fe rich forsterite identified by EDS analysis. Forsterite, Mg2[SiO4] , and fayalite, Fe2[SiO4] , form a solid solution series. This Hopkington, NH specimen is on the forsterite side of the series mid-point. |

Species: PREHNITE Locality: Rt. 101 - 101A road cut, Amherst, NH Specimen Size: 7 cm specimen with glassy pale-green prehnite crystals. Field Collected: Tom Mortimer (Aug 1997) Catalog No.: 1029 Notes: |
