| Species: GOETHITE Locality: Long Mtn., Odel, NH Specimen Size: 5 cm specimen. Field Collected: ex Don Swenson, (collection date noted as Aug. 1992) Catalog No.: 1829 Notes: Interesting specimen from an undocumented locality, although Long Mtn. is noted under Stark, NH by Phillip Morrill for amethyst. |
Species: GOETHITE Locality: Mine Ledge, Surry, NH Specimen Size: 2.2 cm field of view Field Collected: Tom Mortimer Catalog No.: Notes: Eleven image stack with Helicon Focus. | |
Species: GOETHITE Locality: Knox Mtn. Ossipee, NH Specimen Size: 7 mm field of view. Reddish goethite crystal on right, smoky quartz crystal on left. Field Collected: Tom Mortimer Catalog No.: u252 Notes: When I collected this, I thought this might be a danalite crystal, or perhaps monazite based on the color and the miarolitic cavity environment. The shape suggest garnet, but I have never seen garnet in a NH miarolitic cavity. An EDS analysis showed only Fe (of elements > sodium), so goethite/limonite. This is likely a pseudomorph after pyrite. |

Species: GOETHITE Locality: Stoddard Mine, Westmoreland, NH Specimen Size: 9 mm field of view. Dark brown, resinous, goethite in quartz with green malachite Field Collected: Tom Mortimer Catalog No.: TBC Notes: Goethite confirmed by EDS analysis (BC136). For some time I had wondered what this brown resinous mineral was. The analysis and surrounding malachite indicate a former chalcopyrite mineral altered to goethite. |

Species: GOETHITE pseudo after Pyrite Locality: Ore Hill Rd. Circle, Sugar Hill, NH Specimen Size: 2.2 cm goethite pseudomorph after pyrite Field Collected: Don Swenson 5/09 Catalog No.: A Don Swenson specimen Notes: |

Species: GOETHITE Locality: Mine Ledge, Surry, NH Specimen Size: 4 mm field of view. Furry goethite balls on quartz. Field Collected: Tom Mortimer Catalog No.: u1502 Notes: |

Species: GOETHITE Locality: Mine Ledge, Surry, NH Specimen Size: 1.5 mm goethite crystal Field Collected: Tom Mortimer Catalog No.: u778 Notes: Goethite blade crystals like this are rare. |

Species: GOETHITE Locality: Johnson Rd., Bow, NH Specimen Size: 2.5 cm specimen. Field Collected: 2016 Catalog No.: u2165 Notes: A January, 2018 carbon tape EDS analysis showed mostly an iron oxide (goethite) with a bit of zinc and sulfur. I had considered this deep orange mineral might be minium, the lead-oxide mineral, due to all the decomposing galena nearby. |
Species: GOETHITE balls in quartz Locality: Mine Ledge, Surry, NH Specimen Size: 2.8 mm field of view. Yellow goethite balls on first growth goethite coated quartz crystal overgrown by clear second growth quartz crystal. Field Collected: Tom Mortimer Catalog No.: u2411 Notes: |
|
Species: GOETHITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 2.5 mm field of view Field Collected: Bob Whitmore - from a tub of Palermo phosphate rocks gifted by Bob. Catalog No.: u2460 Notes: Visual ID. A goethite "worm." |

Species: GOETHITE ? Locality: Palermo Mine, N. Groton, NH Specimen Size: 1.1 mm field of view Field Collected: Bob Whitmore - from a tub of Palermo phosphate rocks gifted by Bob. Catalog No.: TBC Notes: Visual ID. The interior of these nodules is very granular, as seen in the top broken section. |
