The purpose of this study is to obtain information on the origin of mineral ores by ion beam induced luminescence (IBIL) analysis of natural mineral pigments, which is a method of detecting and analyzing the electromagnetic waves (ion beam induced luminescence) of several eV generated by the relaxation process of the outer shell electrons excited by an ion beam. The IBIL analysis was conducted using a natural mineral pigments called "HAKUSUIMATSU" to identify the ore type, and then experiments were conducted on the identified ores from several different regions, and it was found that the IBIL analysis showed different spectra depending on the region of origin.
