During the upcoming PCMA seminar, Dr. Zuzanna Kabacińska (Geochronology Research Unit, Institute of Geology, Adam Mickiewicz University, Poznań, Poland) will deliver a presentation: “Electron Paramagnetic Resonance (EPR) in archaeology and geology: principles and applications. Perspectives of EPR dating of lime mortars”.
Abstract: Electron Paramagnetic Resonance (EPR), also known as Electron Spin Resonance (ESR), belongs to the so-called Trapped Charge Dating methods, which give the time of the crystal formation or its last exposure to heat or light. The presentation aims at explaining the principles and showing the applications of EPR in archaeology and geology.
The second part of the presentation will focus on the preliminary results of the Polish Returns NAWA project „Radiation defects in anthropogenic carbonates: Towards Electron Paramagnetic Resonance dating of lime mortars and plasters (DANCER)”, which is being implemented by dr Zuzanna Kabacińska at the Institute of Geology, Adam Mickiewicz University in Poznań. The project aims at establishing EPR as a dating technique applicable to historical binders, which can currently be dated only by radiocarbon (14C) and optically stimulated luminescence (OSL) methods.
Dr. Zuzanna Kabacińska, a physicist and archaeologist, applies her interdisciplinary background to archaeological and geological materials, with a particular focus on absolute dating methods.
The seminar will be held on Thursday, 13th March 2025, at 2 pm (Warsaw time) – on the Zoom platform and at the PCMA UW office (15/17 Tyniecka st. 02-630 Warsaw). To receive the link, please write to seminarium.pcma@uw.edu.pl
