Popis: The article represents the results of the research of the chemical composition of mammoth tusk Mammuthus Primigenius and its phase transformation using thermogrammetric (TGA) and X-ray spectroscopy analysis (XRD). The elemental analysis of mammoth tusk showed, that besides basic elements in the structure of hydroxyapatite (HAP) contains magnesium ions, i.e. hydroxyapatite in the studied samples is presented in magnesium-substituted form. The thermal decomposition of mammoth tusk components occurs in wide temperature range with a change in the structure of the mineral part from hydroxyapatite to whitlockite. It was found that this process is caused by the presence of magnesium ions.
