PYRRHOTITE Mine Falls Park, Nashua, NH 5 cm specimen of massive pyrrhotite on milky quartz.	Species: PYRRHOTITE Locality: Mine Falls Park, Nashua, NH Specimen Size: 5 cm specimen of massive pyrrhotite on milky quartz. Field Collected: Tom Mortimer Catalog No.: 1464 Notes: Pyrrhotite is slightly magnetic, distinguishing it from pyrite
PYRRHOTITE Former Pizza Hut site, Rt. 101A, Exit 7W Everett Turnpike, Nashua, NH 1.2 mm pyrrhotite crystal group. PYRRHOTITE Former Pizza Hut site, Rt. 101A, Exit 7W Everett Turnpike, Nashua, NH 1.2 mm pyrrhotite crystal group, alternate lighting	Species: PYRRHOTITE Locality: Former Pizza Hut site, Rt. 101A, Exit 7W Everett Turnpike, Nashua, NH Specimen Size: 1.2 mm pyrrhotite crystal group Field Collected: Tom Mortimer (June, 2012) Catalog No.: u1294 Notes: In thin calcite vein, disolved with away vineger. Second view with alternate light orientation. Similar thin, tabular, pyrrhotite crystals were found by Scott Whittemore at nearby Mine Falls Park, Nashua, in the early 1990's.
PYRRHOTITE Former Pizza Hut site, Rt. 101A, Exit 7W Everett Turnpike, Nashua, NH 0.8 mm pyrrhotite crystal.	Species: PYRRHOTITE Locality: Former Pizza Hut site, Rt. 101A, Exit 7W Everett Turnpike, Nashua, NH Specimen Size: 0.8 mm pyrrhotite crystal. Field Collected: Tom Mortimer (June, 2012) Catalog No.: u1294 Notes: Found in thin calcite vein.
PYRRHOTITE Former Pizza Hut site, Rt. 101A, Exit 7W Everett Turnpike, Nashua, NH 0.7 mm pyrrhotite crystal.	Species: PYRRHOTITE Locality: Former Pizza Hut site, Rt. 101A, Exit 7W Everett Turnpike, Nashua, NH Specimen Size: 0.7 mm pyrrhotite crystal. Field Collected: Tom Mortimer (June, 2012) Catalog No.: u1294 Notes: Found in thin calcite vein. There appears to be an undisolved substrate of calcite behind this thin crystal of pyrrhotite. Part of a clear adularia crystal is in the upper right of the photo.
PYRRHOTITE Mine Falls Park, Nashua, NH 4.5 mm pair of co-planer, oxidized, pyrrhotite crystals with small pyrie crystal, top right.	Species: PYRRHOTITE Fe_1-xS (x = 0 - 0.2) Locality: Mine Falls Park, Nashua, NH Specimen Size: 4.5 mm pair of co-planer, oxidized, pyrrhotite crystals with small pyrite crystal, top right. Field Collected: Bob Janules Catalog No.: u1337 Notes:
PYRRHOTITE Rt. 93 Road Cut, Campton, NH 2.5 cm specimen	Species: PYRRHOTITE Locality: Rt. 93 Road Cut, Campton, NH Specimen Size: 2.5 cm specimen Field Collected: Clayton Ford, ex. Bob Whitmore Catalog No.: 1880 Notes: This bronzy-metalic mineral was originally thought to be pentlandite, a nickle-iron sulfide. This Rt. 93 Campton, NH occurrence was responsible for pentlandite being included on New Hampshire mineral species lists for many years. A Bob Whitmore gift of this TN specimen allowed me to have it analyzed, (EDS analysis) . There is no nickle present, (two sample points probed). The species is pyrrhotite. It is slightly magnetic. Pentlandite and pyrrhotite are visually indistinguishable. These two species are frequently found mixed together. There are only a handful of specimens from this occurrence. It is possible that one of these may contain pentlandite, but lacking any past or present analytic data, I have deleted pentlandite from my NH mineral species list.
PYRRHOTITE Palermo Mine, N. Groton, NH 6 cm specimen with brown thin plates of metalic pyrrhotite on triphylite. PYRRHOTITE Palermo Mine, N. Groton, NH 8 mm zoom view of dark-bronze pyrrhotite in triphylite.	Species: PYRRHOTITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 6 cm specimen with brown thin plates of metalic pyrrhotite on triphylite. Field Collected: Bob Wilken Catalog No.: 1917 Notes: This pyrrhotite is weakly magnetic, a diagnostic test that differentiates it from pyrite. Pyrrhotite is reported from the Palermo Mine.
