Zoned Olivines in Metallurgical Slags of the Bronze Age:Electron Microscopy and Raman Mapping

摘要

In this work,we studied the zoned olivine crystals from historical metallurgical slags by means of hyperspectral Raman mapping and Raman spectroscopy.As a result,we detected 3 crystal zones:central,intermediate and peripheral.The most important was the"gap"area within the intermediate zone with a Raman band typical for olivine.This defective area was formed due to quick melt crystallization and crystal absorption of glass microparticles and non-structural impurities.
