Writeup from MB 101:
Tupelo 34.24216°N, 88.77594°W Mississippi, USA Found: 30 April 2012 Classification: Enstatite chondrite (EL6) History: Ms. O'Connell and Mr. Doherty found the meteorite while looking for Indian artifacts in a cultivated field on his family farm, a recorded Archaic site (22Le1064). Ms. O'Connell spotted it and showed it to Mr. Doherty who realized that is was unlike the stone tools that had been found there. Web research then led them to believe that it was a meteorite. Petrography: (H. McSween, UTenn) The meteorite is an enstatite chondrite, composed of abundant chondrules, with significant amounts of Fe/Ni metal and sulfides. The only silicate phase is enstatite (En98, homogeneous, as determined by electron probe), and no olivine has been found. Most of the chondrule outlines are obscured by metamorphic recrystallization. Analyses of Si and Ni in kamacite, partitioning of Ni between phosphide and kamacite, Ti and Cr in troilite, and Mn, Fe, and Mg in alabandite all confirm that the meteorite is an EL6 chondrite (Zhang et al., 1995). Specimens: 20 g at AMNH, 0.2 g at UTenn, main mass with finder. | ||||||||||||||||||||||||||||||||
