AEGIRINE Peter's Quarry, Hurricane Mtn., Conway, NH 1.3 cm splintery mass	Species: AEGIRINE NaFeSi₂O₆ Locality: Peter's Quarry, Hurricane Mtn., Conway, NH Specimen Size: 1.3 cm splintery mass Field Collected: Bob Wilken - 2021 Catalog No.: u2564 Notes: Aegirine confirmed by EDS analysis The chemistry imputed from this analysis is Na_0.95Fe_0.71Si₂O_3.6 , normalized for 2 Si. This is close to the desired Na:Fe ratio of 1:1.... much closer than for the amphibole arfvedsonite and riebeckite species reported from Hurricane.

AEGIRINE Hurricane Mtn., Conway, NH 2 cm vertical field of view AEGIRINE Hurricane Mtn., Conway, NH 10 mm vertical field of view	Species: AEGIRINE Locality: Hurricane Mtn., Conway, NH Specimen Size: 2 cm vertical field of view and 10 mm close-up view. Field Collected: Leroy Grant - 1970's Catalog No.: 2154 Notes: In 2022, Bob Wilken found and identified (EDS) aegirine at Hurricane Mtn. These were mostly micro green splinters in the cores of matrix embedded arfvedsonite crystals. Alerted to this association, I reviewed a small lot of Leroy Grant Hurricane specimens, (acquired 2018), that I had dismissed as typical, non-descript, embedded arfvedsonite. One miniature chunk had these aegerine crystals. These were not as green as Bob's find, perhaps due to greater weathering. Aegirine has been on New Hampshire species lists for decades, reported from Red Hill, Moultonborough, My Red Hill collecting efforts had failed to find an example, so Bob's discovery of the Hurricane Mtn. occurrence was most satisfying.
AEGIRINE Hurricane Mtn., Conway, NH 10 mm vertical field of view	Species: AEGIRINE Locality: Hurricane Mtn., Conway, NH Specimen Size: 10 mm vertical field of view Field Collected: Leroy Grant - 1970's Catalog No.: 2154 Notes: Another aegirine crystal on the 2154 specimen, very dark green.
AEGIRINE ? Red Hill, Moultonboro, NH 4 mm field of view	Species: AEGIRINE ? Locality: Red Hill, Moultonboro, NH Specimen Size: 4 mm field of view Field Collected: Tom Mortimer Catalog No. poly bag, awaiting EDS: Notes: Aegirine is reported from Red Hill. In my review of saved Red Hill samples, I found one that had these splintery interiors of hastingsite. These reminded me of the Hurricane aegirine interiors of arfvedsonite. These Red Hill ones appear quite altered. Perhaps these black crystals are altering aegirine? All Red Hill hastingsite has a platy cleavage. These are different.
