Locality: Government Pit, Albany, NH
Specimen Size: 7 cm specimen. Green Glauconite coating on Microcline and smoky quartz.
Field Collected: Tom Mortimer
Catalog No.: 1289
Notes: This specimen was previously believed to be an example of New Hampshire nontronite. The specimen has the appearance of what collectors have thought to be nontronite-chloropal. Nontronite (= chloropal) is reported in several references as occurring in the Conway area (e.g. Philip Morrill New Hampshire Mines and Mineral Localities). However, no confirmed/analyzed examples have been located. An EDS analysis showed this dusty, green, coating to be glauconite. Note: glauconite has potassium as an essential element, it is not present in nontronite.
Nontronite has been removed from my NH species list until a proven sample can be found.
