DANALITE   Iron Mtn., upper adit pit, Bartlett, NH
4 mm field of view. Orange-red bipyramidal danalite crystals in quartz.

Locality:          Iron Mtn., upper adit pit, Bartlett, NH
Specimen Size: 4 mm field of view. Orange-red bipyramidal danalite crystals in quartz.

DANALITE   Iron Mtn., upper adit pit, Bartlett, NH
1.2 mm red octahedral danalite crystal with quartz.

Locality:          Iron Mtn., upper adit pit, Bartlett, NH
Specimen Size: 1.2 mm red octahedral danalite crystal with quartz.
Field Collected: Tom Mortimer
Catalog No.: u1012
Notes: These danalite crystals were found totally embedded in quartz. Breaking out undamaged crystals was very difficult. For every good one salvaged, several were broken.

DANALITE   Iron Mtn., upper adit pit, Bartlett, NH
1.7 mm complex danalite crystal with quartz.

Locality:          Iron Mtn., upper adit pit, Bartlett, NH
Specimen Size: 1.7 mm complex danalite crystal with quartz.
Field Collected: Tom Mortimer
Catalog No.: u895
Notes: This danalite face appears to be a group of three intergrown crystals.

DANALITE   Iron Mtn., upper adit pit, Bartlett, NH
2 mm danalite crystal in quartz.

Locality:          Iron Mtn., upper adit pit, Bartlett, NH
Specimen Size: 2 mm danalite crystal in quartz.
Field Collected: Tom Mortimer
Catalog No.: u893
Notes: Unfortunately the apex is dinged on this one.

DANALITE   Iron Mtn., upper adit pit, Bartlett, NH
3 mm field of view. Pair of danalite crystals in quartz.

Locality:          Iron Mtn., upper adit pit, Bartlett, NH
Specimen Size: 3 mm field of view. Pair of danalite crystals in quartz.
Field Collected: Tom Mortimer
Catalog No.: u893
Notes: Another pair of danalite crystals on specimen u893

DANALITE   Iron Mtn., upper adit pit, Bartlett, NH
Field of view about 5 mm. Partially exposed yellow crystal in center may be helvite.

Locality:          Iron Mtn., upper adit pit, Bartlett, NH
Specimen Size: Field of view about 5 mm. Partially exposed yellow crystal in center may be helvite. Danalite forms a series with helvite and genthelvite. Encyclopedia of Minerals states danalite may be "lemon yellow."
Field Collected: Tom Mortimer
Catalog No.: u892
Notes: Many of the Iron Mtn. danalite crystals have a greenish-yellow helvite core. A broken crystal cross-section, lower center, shows a red rind around a glassy yellow core. An article by D. Burt, American Mineralogist vol. 65, pages 355-380, 1980, notes that at the Iron Mtn., Bartlett, New Hampshire locality, "the danalite crystals are zoned, with helvite cores and danalite rims."

Cross-section of penetration pair of zoned 2 mm danalite crystals showing a danalite red outer rind with yellow-green helvite core.

Locality:          Iron Mtn., upper adit pit, Bartlett, NH
Specimen Size: Cross-section of penetration pair of zoned 2 mm danalite crystals showing a danalite red outer rind with yellow-green helvite core.
Field Collected: Tom Mortimer
Catalog No.: u1030
Notes: A excellent example of a helvite core surrounded by a danalite rim.
