Research projects:

Determination of the relative age of fossil teeth using the fluorine dating method

The main component of teeth and bone is hydroxylapatite Ca10(PO4,CO3)6(OH,CO3)2 , whose chemical and isotopic composition is an important indicator in paleoenvironmental studies. The structure of apatite allows numerous isomorphic substitutions, and its composition may be altered after deposition in sediment. One of the transformation processes of bioapatite is F– substitutions in the (OH)– position, the quantification of which has been used in the past to determine the age of fossil bones. However, due to the complex crystallochemistry of apatite and complex sub-deposition processes, a number of problems have been identified in the interpretation of results not only when comparing samples from different locations, but also within a single site. With the development of research methods used in the reconstruction of palaeoenvironments, infrared spectroscopy (FTIR) and Raman microscopy have become increasingly important as tools for assessing the degree of diagenetic alteration of fossils (e.g. by determining CI crystallinity and C/P ratio). The main goal of this research is to test suitability of both methods for determining the age of fossil teeth based on the F contents in their structure.

Preliminary isotope study of fossils from the Cradle of Humankind caves, South Africa

Underground karst forms of the Bolt’s Farm located within the UNESCO World Heritage List Hominid Fossil Sites of South Africa World Heritage Site are being intensively explored by geologists and anthropologists searching for fossil material of Pliocene and Pleistocene fauna and, most importantly, archaic human species. A goal of our preliminary study is to asses the suitability of oxygen isotope analysis by SIMS and GS-IRMS as well as spectroscopic analysis using FTIR and Raman microscopy for the investigation of mammalian fossil teeth from the Bolts’ Farm.

Development of the reference material(s) for U-Pb dating of apatite

Minerals of the apatite group commonly incorporate trace amounts of uranium into their structure. Due to the different closure temperature of the U-Pb system for apatite, it can complement zircon or it may serve as the sole way of the age determination of rocks. In cases, where limited amount of the material is available, the in situ analysis using SIMS is the method of choice. However, SIMS is hampered by the lack of homogeneous apatite reference materials, and therefore, the goal of our project is to develop new, well-characterized reference material(s) for U-Pb dating of apatite.
