Mossbauer spectroscopy study of the metallic particles extracted from the Antarctic chondrite Allan Hills-769

Pieces of the Antarctic L6 chondrite Allan Hills-769 (ALH-769) have been submitted to magnetic and chemical separation in order to obtain small metallic grains of the special ordered crystal structure of AuCu-type tetrataenite. The samples have been analyzed in each step of preparation by Mossbauer...

Description
Summary:Pieces of the Antarctic L6 chondrite Allan Hills-769 (ALH-769) have been submitted to magnetic and chemical separation in order to obtain small metallic grains of the special ordered crystal structure of AuCu-type tetrataenite. The samples have been analyzed in each step of preparation by Mossbauer spectroscopy and other techniques.
