Species: RUTHERFORDINE Locality: Charles Davis Mine, N. Groton, NH Specimen Size: 2.5 mm zone of bright yellow rutherfordine Field Collected: Tom Mortimer (June 2000) Catalog No.: u405 Notes: A grain from this zone disolves slowly in cold muriatic acid with a few occasional bubbles, suggesting a carbonate. This yellow mineral is not fluorescent, but the specimen surface has much, nearly (daylight) invisible autunite. The specimen is weakly radioactive. Rutherfordine is reported from the nearby Palermo Mine. |

Species: RUTHERFORDINE Locality: Chickering Mine, Walpole, NH Specimen Size: 1.5 mm field of view Field Collected: Tom Mortimer Catalog No.: u1155 Notes: Rutherfordine suggested by EDS analysis. (KD set 19). Square outline suggests a replacement of a former uraninite crystal. The earthy yellow zone has a pale green fluorescence in SW UV that is reasonable for rutherfordine. |

Species: RUTHERFORDINE Locality: Palermo Mine, Groton, NH Specimen Size: 5.0 mm field of view, daylight and SW UV views. Field Collected: From a tub of Palermo rocks gifted by Bob Whitmore, 2009 Catalog No.: u2525 Notes: The rutherfordine is surrounded by and aureole of autunite that is invisible in the daylight view. I have collected and verified rutherfordine from other NH localities, but this is first that I have seen from Palermo. There may be two different minerals here, a yellow one and a cream-colored one. |
