CLINOZOISITE Joppa Hill, Amherst, NH 4 mm terminated clinozoisite crystal in bed of diopside crystals.	Species: CLINOZOISITE Locality: Joppa Hill, Amherst, NH Specimen Size: 4 mm terminated clinozoisite crystal in bed of diopside crystals, two views. Field Collected: Tom Mortimer Catalog No.: u1048 Notes:
CLINOZOISITE Joppa Hill Locale, Amherst, NH 4 mm terminated brown crystal with diopside ZOISITE Crystal form	Species: CLINOZOISITE Locality: Joppa Hill Locale, Amherst, NH Specimen Size: 4 mm terminated brown crystal with diopside Field Collected: Tom Mortimer Catalog No.: u1048 Notes: This is a re-photo of this specimen. The crystal drawing is of a zoisite. It is a good match for this Joppa Hill crystal, including the small triangular face near the termination. However, a 2022 Raman analyses of Joppa Hill Clinozoisite-Zosite dimorphs by George Adleman favored a clinozoisite identification, see Raman analysis.
CLINOZOISITE Joppa Hill, Amherst, NH 2.8 cm field of view	Species: CLINOZOISITE Locality: Joppa Hill, Amherst, NH Specimen Size: 2.8 cm field of view Field Collected: Tom Mortimer Catalog No.: NC Notes: Specimen used for Raman analysis
CLINOZOISITE Joppa Hill Locale, Amherst, NH 1.3 mm field of view. Cluster of zoisite crystals. CLINOZOISITE Joppa Hill Locale, Amherst, NH 1.5 mm field of view. Cluster of zoisite crystals.	Species: CLINOZOISITE Locality: Joppa Hill Locale, Amherst, NH Specimen Size: 1.3 mm field of view, (top photo). 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, additional analysis is required to differentiate these two species. The steep termination initially biased my [tm] opinion to zoisite.
CLINOZOISITE Joppa Hill Locale, Amherst, NH 1.3 mm field of view	Species: CLINOZOISITE Locality: Joppa Hill Locale, Amherst, NH Specimen Size: 1.3 mm field of view Field Collected: Tom Mortimer Catalog No.: u487 Notes: This is a re-photo of this specimen. Zoisite and clinozoisite are dimorphs, so EDS cannot differentiate these species. George Adleman examined two Joppa Hill specimens that I sent with Raman spectroscopy. The Raman result favored the clinozoisite identification over zoisite. Two RAMAN plots are included.
CLINOZOISITE Joppa Hill Locale, Amherst, NH 0.8 mm field of view	Species: CLINOZOISITE Locality: Joppa Hill Locale, Amherst, NH Specimen Size: 0.8 mm field of view Field Collected: Tom Mortimer Catalog No.: u485 Notes: Both crystal termination ends are visible.
CLINOZOISITE Joppa Hill locale, Amherst, NH 2.8 cm field of view	Species: CLINOZOISITE Locality: Joppa Hill locale, Amherst, NH Specimen Size: 2.8 cm field of view Field Collected: Don Swenson Catalog No.: A Don Swenson specimen. Collected 2004. Notes: This is the best Joppa Hill clinozoisite specimen that I have seen, both in size and crystal quality. Pale green diopside and orange grossular are also present on this specimen. Clinozoisite is uncommon in New Hampshire.
