Notes:
Locality: Palermo Mine, N. Groton, NH

Locality: Palermo Mine, N. Groton, NH
Specimen Size: 3 mm field of view. Goyazite with bipyramidal quartz.
Field Collected: Walter Lane. A Bob Janules specimen.
Catalog No.:
Notes: This is goyazite habit type 4.
Locality: Keyes Mine, Orange, NH
Specimen Size: 6 mm field of view. Goyazite crystals to 0.8 mm on fairfieldite/messelite
Field Collected: Ingeborg Burgraff - 1984
Catalog No.: u1209
Notes: Goyazite from the Keyes Mines is rare. This specimen is the only one the author has seen.
Locality: Keyes Mine, Orange, NH
Specimen Size: 6 mm field of view. Goyazite crystals to 0.8 mm on fairfieldite/messelite, (the steep white rhombs in the background).
Field Collected: Ingeborg Burgraff - 1984
Catalog No.: u1209
Notes: Another view from above specimen.
The rough surface of many pseudo-cubic goyazite crystals are actually an array of lustrous aligned faces that strongly reflect light at the right incident angle. This affect is present on two of the small crystals on this photograph.
Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: 1.7 mm zoned goyazite crystal, (i.e. goyazite crystal with phantom)
Field Collected: From crate of Palermo rocks given by Bob Whitmore
Catalog No.: u1238
Notes:
Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: 1 mm rhombic goyazite crystal with stippled surface on quartz
Field Collected: Jim Nizamoff (2012)
Catalog No.: u1306
Notes: These goyazite crystals were found in a hydrothermal quartz fracture zone. Goyazite confirmed by EDS analysis.
Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: Largest crystal is 0.7 mm
Field Collected: John Anderson via MMNE give-away.
Catalog No.: u1319
Notes: Large goyazite crystal has many clear apatite crystals on surface, including somewhat out-of-focus group on front corner. Orange patch on top is iron oxide staining.
