EPIDOTE Rt. 101 - 101A Road Cut, Amherst, NH 5 mm field of view	Species: EPIDOTE Locality: Rt. 101 - 101A Road Cut, Amherst, NH Specimen Size: 5 mm field of view Field Collected: Tom Mortimer Catalog No.: u320 Notes:
EPIDOTE Rt. 101 - 101A Road Cut, Amherst, NH 1 mm crystal pair	Species: EPIDOTE Locality: Rt. 101 - 101A Road Cut, Amherst, NH Specimen Size: 1 mm crystal pair Field Collected: Tom Mortimer Catalog No.: Notes: The serrated edges are seen on many of the micro epidote crystals from this locality.
EPIDOTE Rt. 101 - 101A Road Cut, Amherst, NH 3 mm field of view. Dark prismatic epidote on adularia	Species: EPIDOTE - REE rich Locality: Rt. 101 - 101A Road Cut, Amherst, NH Specimen Size: 3 mm field of view. Dark prismatic epidote on adularia. Field Collected: Tom Mortimer Catalog No.: u2253 Notes: These dark crystals from the Rt. 101 - 101A locality were initially thought to be allanite, but EDS analysis showed the rare earth element (REE) was too low to be allanite. They are REE enriched epidote. Epidote chemistry is: Ca₂Al₂(Fe³⁺,Al)Si₃O₁₂(OH) , Fleischer 2008 Allanite-(Ce) chemistry is: CaCeFe²⁺Al₂(Si₂O₇)(SiO₄)O(OH) , Fleischer 2008 A second polished grain, quantitative, EDS analysis , BC243, also indicated a REE rich epidote, with about 0.15 APFU REE content.
EPIDOTE Rt. 101 - 101A Road Cut, Amherst, NH 2 mm cluster of bladed epidote crystals on adularia.	Species: EPIDOTE - REE rich Locality: Rt. 101 - 101A Road Cut, Amherst, NH Specimen Size: 2 mm cluster of bladed epidote crystals on adularia. Field Collected: Tom Mortimer Catalog No.: u299 Notes: The REE rich epidote also occurs in this tabular habit.
EPIDOTE Rt. 101 - 101A Road Cut, Amherst, NH 1.5 mm high epidote on adularia.	Species: EPIDOTE - REE rich Locality: Rt. 101 - 101A Road Cut, Amherst, NH Specimen Size: 1.5 mm high epidote on adularia. Field Collected: Tom Mortimer Catalog No.: u282 Notes:
EPIDOTE Cambridge, NH 10 mm field of view. Epidote crystals to 0.8 mm	Species: EPIDOTE Locality: Cambridge, NH Specimen Size: 10 mm field of view. Epidote crystals to 0.8 mm Field Collected: Cliff Trebilcock Catalog No.: A Cliff Trebilcock specimen Notes: Substrate matrix is milky quartz.
EPIDOTE Holt's Locality, Cambridge, NH 5.5 mm field of view	Species: EPIDOTE Locality: Holt's Locality, Cambridge, NH Specimen Size: 5.5 mm field of view Field Collected: Cliff Trebilcock Catalog No.: 2124 Notes: This pink mineral embedded in the green epidote was initially visually identified as piemontite. Epidote confirmed by EDS analysis, (BC377, set27). Not a smidgen of manganese (Mn), an essential element for piemontite, was detected, (4 spots on 2 grains probed). A 2023 Raman analysis was also in agreement with the epidote identification. The black trace is from the Holt's Locality specimen, the red trace is a RUFF reference plot for epidote.
EPIDOTE Government Pit, Albany, NH 4.2 mm field of view	Species: EPIDOTE Locality: Government Pit, Albany, NH Specimen Size: 4.2 mm field of view Field Collected: Don Dallaire Catalog No.: Don Dallaire specimen #4094 Notes:
