KRYZHANOVSKITE Palermo Mine N. Groton, NH 1.7 mm field of view. Red-brown octahedral kryzhanovskite crystals.	Species: KRYZHANOVSKITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 1.7 mm field of view. Red-brown octahedral kryzhanovskite crystals. Field Collected: ex. Bill Henderson Catalog No.: A Joe Mulvey specimen, ex. Bill Henderson Notes:
KRYZHANOVSKITE Parker Mtn. Mine, Center Strafford, NH 0.8 mm octahedral kryzhanovskite crystals	Species: KRYZHANOVSKITE (Fe³⁺,Mn)Fe³⁺₂(PO₄)₂(OH)₃ Locality: Parker Mtn. Mine, Center Strafford, NH Specimen Size: 0.8 mm octahedral kryzhanovskite crystals Field Collected: Gene Bearss Catalog No.: A Gene Bearss collection specimen Notes: Broken crystals on this specimen have a vitreous, red-brown, interior. These are the finest NH kryzhanovskite crystals the author has seen.
KRYZHANOVSKITE Palermo Mine, N. Groton, NH 0.25 mm kryzhanovskite octahedron	Species: KRYZHANOVSKITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 0.25 mm kryzhanovskite octahedron Field Collected: Bob Whitmore - from a tub of Palermo phosphate rocks gifted by Bob. Catalog No.: u2425 Notes: This phosphate chunk had a zone of mostly granular kryzhanovskite, but the granular area had some voids with tiny crystals like this one. Most crystals were almost invisible, unless they had reflecting light off a crystal face.
KRYZHANOVSKITE Palermo Mine, N. Groton, NH 0.20 mm kryzhanovskite crystals	Species: KRYZHANOVSKITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 0.20 mm kryzhanovskite crystals Field Collected: Bob Whitmore - from a tub of Palermo phosphate rocks gifted by Bob. Catalog No.: u2425 Notes: This phosphate chunk had a zone of mostly granular kryzhanovskite, but the granular area had some voids with tiny crystals like this one. Most crystals were almost invisible, unless they had reflecting light off a crystal face.
KRYZHANOVSKITE Palermo Mine, N. Groton, NH 0.20 mm kryzhanovskite crystal with cacoxenite? ball.	Species: KRYZHANOVSKITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 0.20 mm kryzhanovskite crystal with cacoxenite? ball. Field Collected: Bob Whitmore - from a tub of Palermo phosphate rocks gifted by Bob. Catalog No.: u2425 Notes:
KRYZHANOVSKITE Palermo Mine, N. Groton, NH 0.25 mm kryzhanovskite crystal.	Species: KRYZHANOVSKITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 0.25 mm kryzhanovskite crystal. Field Collected: Bob Whitmore - from a tub of Palermo phosphate rocks gifted by Bob. Catalog No.: u2425 Notes:
KRYZHANOVSKITE Palermo Mine, N. Groton, NH 3 cm (vertical) specimen with granular mass of kryzhanovskite in upper half.	Species: KRYZHANOVSKITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 3 cm (vertical) specimen with granular mass of kryzhanovskite in upper half. Field Collected: Bob Whitmore - from a tub of Palermo phosphate rocks gifted by Bob. Catalog No.: u2425 Notes: Sub mm kryzhanovskite crystals are present within this granular mass.
KRYZHANOVSKITE Palermo Mine, Groton,, NH 1.3 mm field of view.	Species: KRYZHANOVSKITE Locality: Palermo Mine, Groton, NH Specimen Size: 1.3 mm field of view. Field Collected: From a tub of Palermo rocks gifted by Bob Whitmore, 2009 Catalog No.: u2526 Notes:
KRYZHANOVSKITE Valencia Mine, Groton, NH The lower complete xl facet is ~0.43 mm across KRYZHANOVSKITE Valencia Mine, Groton, NH 6.0 mm field of view	Species: KRYZHANOVSKITE Locality: Valencia Mine, Groton, NH Specimen Size: Top photo, the lower complete xl facet is ~0.43 mm across. Field Collected: Bob Wilken Catalog No.: A Bob Wilken specimen & photo Notes: Kryhanovskite chemistry from mindat.org is (Fe³⁺,Mn²⁺)₃(PO₄)₂(OH,H₂O)₃ . Chemistry from EDS analysis of this specimen is Fe_1.31Mn _0.66Mg_0.28P_2.0O_10.9 , normalized for 2 P. The (Fe + Mn) is low for the 2 P normalization for kryhanovskite. The literature does not have a kryhanovskite analysis that includes Mg. The sarcopside chemistry could also be considered: (Fe²⁺,Mn²⁺,Mg)₃(PO₄)₂ .
