Abstract

We analyzed amber samples from the Baltic region (Mexico) and imitation amber, in order to develop an analytical method allowing to discriminate between different samples causing little or no damage. We propose a two-step method that involves the use of Laser Induced Breakdown Spectroscopy (LIBS) to obtain spectra, and Discriminant Analysis to analyze the resulting data. We studied the damage caused to the samples using confocal optical microscopy.
