DIOPSIDE Wheeler Mtn., Winchester, NH 3 cm specimen with prism of iron-stained diopside.	Species: DIOPSIDE Locality: Wheeler Mtn., Winchester, NH Specimen Size: 3 cm specimen with prism of iron-stained diopside. Field Collected: Tom Mortimer (1994) Catalog No.: 1813 Notes: Although their color is somewhat similar to the epidote that is common at this locality, when viewed down the prism axis these crystals appear square to rectangular, quite different than the epidote. I had set these aside for about fifteen years. When I viewed them again recently, I thought they might be hedenbergite. The EDS analysis result that came back in Jan. 2012 indicated they were clearly on the diopside end of the diopside - hedenbergite series, (Mg:Fe about 2:1). These diopside crystals are the largest New Hampshire examples the author has seen.
DIOPSIDE Wheeler Mtn., Winchester, NH Central (terminated) diopside crystal is 1.0 cm	Species: DIOPSIDE Locality: Wheeler Mtn., Winchester, NH Specimen Size: Central (terminated) diopside crystal is 1.0 cm Field Collected: Tom Mortimer (1994) Catalog No.: 1812 Notes: The EDS analysis sample was taken from this specimen.
DIOPSIDE Wheeler Mtn., Winchester, NH 1.6 cm diopside crystal with ferrohornblende inclusions.	Species: DIOPSIDE Locality: Wheeler Mtn., Winchester, NH Specimen Size: 1.6 cm diopside crystal with ferrohornblende inclusions. Field Collected: Tom Mortimer (1994) Catalog No.: 879 Notes: Terminations on most of these Wheeler Mtn. diopside crystals are crude. Many of the crystals collected contained numerous blades of dark-green ferrohornblende. Very pale lemon-yellow titanite crystals are a frequent association with this diopside. The Wheeler Mtn. locality is at a contact between the Amoonusic Volcanics and a granite body to the west.
