“Prompt gamma-ray activation analysis (PGAA) was applied to well homogenized meteorite samples initially prepared for the wet chemical analysis. By comparing the PGAA data with wet chemical analysis data in literatures, it was confirmed that PGAA can be alternative or even advantageous to wet chemical analysis in terms of the data reliability. Because the same sample can be analyzed by INAA followed by PGAA, data obtained by a combination of PGAA and INAA were proved to enable us to discuss the detailed chemical characteristics of meteorite samples represented by eucritic meteorites (eucrites).”
