HEMATITE Gilman Notch, Center Ossipee, NH 4 mm fov. Hematite needles embedded in quartz.	Species: HEMATITE Locality: Gilman Notch, Center Ossipee, NH Specimen Size: 5 mm fov. Hematite needles embedded in quartz. Field Collected: Jon Herndon - 2008 Catalog No.: 1948 Notes: Gift from Brad Lewis. This specimen is from the "Surprise Pocket". See article by Herndon & Green Rocks and Minerals Mar./Apr. 2011, pgs 168-173.
CHILDRENITE Palermo Mine, N. Groton, NH 4 mm barrel-shaped, pinecone crystal cluster	Species: CHILDRENITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 4 mm barrel-shaped, pinecone crystal cluster Field Collected: Forrest Fogg -1973 Catalog No.: u1561 Notes: A polished grain EDS analysis from an adjacent broken crystal group suggested childrenite. Calcium is not present in the childrenite formula, so the modest Ca peak in the spectrum is somewhat bothersome. (The large spectral peak at the lowest end of the spectrum is due to the carbon coating.) I have not previously seen the pinecone shape and pale-blue coloration in childrenite.
BRAZILIANITE Chickering Mine, Walpole, NH 0.9 mm brazilianite crystal	Species: BRAZILIANITE Locality: Chickering Mine, Walpole, NH Specimen Size: 0.9 mm brazilianite crystal Field Collected: Tom Mortimer Catalog No.: TBC Notes:
BRAZILIANITE Chickering Mine, Walpole, NH 0.7 mm brazilianite crystal	Species: BRAZILIANITE Locality: Chickering Mine, Walpole, NH Specimen Size: 0.7 mm brazilianite crystal Field Collected: Tom Mortimer Catalog No.: TBC Notes:
MITRIDATITE Chickering Mine, Walpole, NH 4 mm field of view	Species: MITRIDATITE Locality: Chickering Mine, Walpole, NH Specimen Size: 4 mm field of view Field Collected: Tom Mortimer Catalog No.: u1733 Notes:
WARDITE Chickering Mine, Walpole, NH Pair of wardite crystals. Largest is 0.7 mm	Species: WARDITE Locality: Chickering Mine, Walpole, NH Specimen Size: Pair of wardite crystals. Largest is 0.7 mm Field Collected: Tom Mortimer Catalog No.: u1696 Notes: Photo from stack of 18 images, 0.05 mm steps, processed with Helicon Focus.
SIDERITE Chickering Mine, Walpole, NH 1.2 mm field of view. Orange second generation siderite rhombs on black earlier generation of siderite.	Species: SIDERITE Locality: Chickering Mine, Walpole, NH Specimen Size: 1.2 mm field of view. Orange second generation siderite rhombs on black earlier generation of siderite. Field Collected: Tom Mortimer Catalog No.: u1677 Notes: Photo from stack of 9 images, 0.04 mm steps, processed with Helicon Focus.
CHILDRENITE Chickering Mine, Walpole, NH 3 mm cluster of oxide coated childrenite crystals.	Species: CHILDRENITE Locality: Chickering Mine, Walpole, NH Specimen Size: 3 mm cluster of oxide coated childrenite crystals. Field Collected: Tom Mortimer Catalog No.: u1724 Notes: Photo from stack of 18 images, 0.05 mm steps, processed with Helicon Focus. At the Chickering Mine, when childrenite is found in weathered siderite vugs, it is frequently coated with an orange oxide.
HYDROXYLHERDERITE Palermo Mine, N. Groton, NH 1.1 mm hydroxylherderite crystal	Species: HYDROXYLHERDERITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 1.1 mm hydroxylherderite crystal Field Collected: Forrest Fogg Catalog No.: u1760 Notes: The crystal termination is a group of small pyramids.
CHABAZITE Joppa Hill Locale, Amherst, NH 4 mm field of view. Cluster of blocky chabazite-(Ca) crystals with dendritic patterns on surface.	Species: CHABAZITE Locality: Joppa Hill Locale, Amherst, NH Specimen Size: 4 mm field of view. Cluster of blocky chabazite-(Ca) crystals with dendritic patterns on surface. Field Collected: Tom Mortimer Catalog No.: u484 Notes: A polished grain EDS analysis was consistant with a chabazite-(Ca) identification, (the large spectral peak below oxygen is due to the carbon coating of the sample). This is the first report of chabazite at the Joppa Hill Locale. It is unknown how common the occurrence chabazite is in a skarn environment. The small cluster of acicular crystals in the lower left may be another zeolite species.
CHABAZITE Joppa Hill Locale, Amherst, NH 4 mm field of view. Cluster of blocky chabazite-(Ca) crystals with dendritic patterns on surface.	Species: CHABAZITE Locality: Joppa Hill Locale, Amherst, NH Specimen Size: 4 mm field of view. Cluster of blocky chabazite-(Ca) crystals with dendritic patterns on surface. Field Collected: Tom Mortimer Catalog No.: u489 Notes: Thin, short prismatic, zoisite crystals are present on most of the specimens with chabazite, along with the common Joppa Hill minerals grossular and diopside. The green mineral appears to be a mica group species.
ZOISITE Joppa Hill Locale, Amherst, NH 1.3 mm field of view. Cluster of zoisite crystals. ZOISITE Joppa Hill Locale, Amherst, NH 1.3 mm field of view. Cluster of zoisite crystals.	Species: ZOISITE Locality: Joppa Hill Locale, Amherst, NH Specimen Size: 1.3 mm field of view. Cluster of zoisite crystals. Field Collected: Tom Mortimer Catalog No.: u487 Notes: Two views. Top view maximizes the reflection from the prism faces to enhance the striations, (at the expense of accurate color rendering). The lower photo reproduces the pale greenish-yellow color of these crystals. A polished grain EDS analysis was consistant with a zoisite identification, (the large spectral peak below oxygen is due to the carbon coating of the sample). The element chemistry of zoisite: Ca₂Al₃Si₃O₁₂(OH) is not that different from chabazite-(Ca): (Ca,K₂,Na₂)₂[Al₂Si₂O₁₂]₂ · 12H₂O , when K and Na substitution are absent. Since zoisite and clinozoisite are dimorphs, a XRD analysis is required to differentiate these two species. The steep termination biases my [tm] opinion to zoisite.
