Pallasite, Main Group
Since its discovery in 1822 several pieces of what were first believed to be independent finds (e.g., Ollague, Salta) have been deemed to be separated pieces of a single fall. Kamacite has prominent Neumann bands due to preterrestrial shock(s.) Olivine is forsterite with an average composition Fa12.30 (Wasson & Choi) or Fa12.20 (McKibbinn et al., 2019). The ∆17O value is -0.27.
