Analytical Metallurgy and Isotopic Forensic Evaluation of the 1957 Ubatuba Magnesium Debris

The scientific and historical narrative of the Ubatuba magnesium fragments began on September 13, 1957, when Ibrahim Sued, a prominent columnist for the Rio de Janeiro newspaper *O Globo*, received an envelope containing an anonymous letter and three highly porous, metallic fragments [1, 2]. The letter writer claimed to have been fishing near the coastal town of Ubatuba in São Paulo, Brazil, when a metallic flying disc climbed rapidly, wobbled, and exploded in a brilliant midday flash, scattering fragments along the beach [2, 3, 4]. Sued forwarded the pieces to Dr. Olavo Fontes, initiating a s
