Species: SPHALERITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 1.2 mm sphalerite crystal in albite vug. Field Collected: Tom Mortimer, 2009 Catalog No.: u964 Notes: A visual identification. Could be another species with a dark mineral coating. |

Species: SPHALERITE Locality: "Old Silver Mine", Woodstock, NH Specimen Size: 2 mm sphalerite crystal in albite vug. Field Collected: Tom Mortimer Catalog No.: u937 Notes: Initially thought this might be tetrahedrite, but EDS analysis (M44, KD set 5) indicated sphalerite. |
Species: SPHALERITE Locality: Mascot Mine, Gorham, NH Specimen Size: 3 cm vug with blue-green sphalerite Field Collected: Don Swenson - late 1980's Catalog No.: Secondary collection Notes: This blueish-green sphalerite is unusual for New Hampshire. Don had this analyzed by Harvard, approximately 1990 |

Species: SPHALERITE Locality: Ore Hill Mine, Warren, NH Specimen Size: 2 cm sphalerite crystal on 5.5 cm specimen Field Collected: Tom Mortimer Catalog No.: 1249 Notes: Perhaps the largest complete sphalerite crystal known from NH. Matrix is iron-stained quartz. |
Species: SPHALERITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 6 mm field of view. Dark sphalerite mass in center Field Collected: From a tub of Palermo phosphate rocks gifted by Bob Whitmore Catalog No.: u1890 Notes: EDS analyzed, BC62. The Na line is close to the Zn line and the S line is very close to the Pb line. These annotations on the EDS plot are very likely due to element miss-assignment by the EDS software. The large carbon peak is due to the carbon coat applied to the sample. Not a remarkable specimen, but a good reference sample for sphalerite at the Palermo Mine. A number of rare Palermo phosphate minerals contain zinc, so specimens containing sphalerite should be closely examined for these rarities. |

Species: SPHALERITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 6 mm field of view. Dark sphalerite mass in center Field Collected: From a tub of Palermo phosphate rocks gifted by Bob Whitmore Catalog No.: u1891 Notes: Another EDS analyzed Palermo sphalerite, BC60. The Na line is close to the Zn line and the S line is very close to the Pb line. These annotations on the EDS plot are very likely due to element miss-assignment by the EDS software. The large carbon peak is due to the carbon coat applied to the sample. Not a remarkable specimen, but a good reference sample for sphalerite at the Palermo Mine. |

Species: SPHALERITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 7 mm field of view. Blue-black disolving sulfide = sphalerite. Field Collected: Clayton Ford acquired by Gordon Jackson 9/22/03, gifted to Tom Mortimer 2016. Catalog No.: u2015 Notes: An EDS analysis (BC181) showed only zinc and sulfur, so sphalerite. From the bluish tarnish, I thought might be bornite. Some of the blocky clear crystals in the foreground are not quartz. Need further study. |
Species: SPHALERITE Locality: Mascot Mine, Gorham, NH Specimen Size: 4 cm specimen with sphalerite crystals to 7 mm. Field Collected: John Anderson Catalog No.: 2096 Notes: This crystal group had a heavy limonite coating. At first glance I thought they were the common siderites from Mascot, but the crystal shape was wrong. A good cleaning revealed these nice sphalerite crystals. Unfortunately a few are dinged. These are the largest euhedral sphalerite crystals I have seen from the Mascot Mine. |

Species: SPHALERITE with Quartz Locality: Shelburne Lead Mine, Shelburne, NH Specimen Size: 8 mm field of view Field Collected: Tom Mortimer - 6/25/99 Catalog No.: u381 Notes: A 19 image stack with Meiji EMZ-5TR. |

Species: SPHALERITE Locality: Mineral Hill, Wakefield, NH Specimen Size: 3.4 cm specimen of massive green sphalerite Field Collected: Don Swenson Catalog No.: A Don Swenson specimen Notes: |
