Species: GOYAZITE Locality: Chickering Mine, Walpole, NH Specimen Size: 0.25 mm pseudo-cubic crystal Field Collected: Tom Mortimer Catalog No.: u1413 Notes: This is a re-do of a 2010 photo. A 2013 Kerry Day EDS analyses plot (no chemistry or light elements) suggested [kd] "An impure Goyazite. Lots of Ca, Ba and Fe substitution." Although almost a dozen goyazite specimens were collected at the Chickering Mine (most by Bob Wilken), this is the only analysis as of 1/25. It would be interesting to see if others had similar "substitutions", or is this something else? |
