Species: BERTRANDITE Locality: Aggregate Industries Quarry, Raymond, NH Specimen Size: 0.7 mm clear crystal cluster Field Collected: Tom Mortimer Catalog No.: u2323 Notes: Brookite and bertrandite are other possible ID's for these. These AIQ crystals do have some appropriately oriented striations (that bring to mind a brookite ID ... suggested by Bob Wilken). The AIQ ones do not have the elongate habit seen in many of the mindat baddeleyite photos. Most of the similar, clear, mindat ones come from volcanic complex environments (Italy & Germany), like the AIQ environment. There are a few tiny zircons also on this specimen. Zircons are more common at AIQ (Zr - favoring baddeleyite) but we also have uncommon anatase (Ti - favoring brookite). |

Species: ADULARIA - K feldspar Locality: Rt. 101 - 101A road cut Amherst, NH Specimen Size: 2.5 cm specimen with magnified 3 mm field of view Field Collected: Tom Mortimer Catalog No.: u2358 Notes: Little contrast in the adularia crystal covered surface. EDs analysis verified a potasium feldspar. Raman analysis pending to differentiate orthoclase from microcline dimorphs. |
