Bluewing 001
40º14.965' N, 118º56.210' W
Pershing County, Nevada, USA
Found 2000 June 14
Achondrite (eucrite)
A 6.1 g stone was found by Paul Gessler while he was searching for meteorites on Bluewing Flat.
Classification and analysis (P. Warren, UCLA): subophitic texture; pyroxene grains are mostly <1 mm and zoned from En67.5 Wo4.8 to En6 Wo25 to En3 Wo15 ; plagioclase is zoned from An89 to An75 , average An82 ; minor and trace phases include
silica, ilmenite, phosphate, fayalite, K-feldspar, metal and troilite; bulk composition is similar to Stannern and Bouvante. See also Warren and Gessler (2001).
Specimens: type specimen, 1.15 g, UCLA; main mass, Gessler.
