The LIAG is a non-university research institute in Hanover, which is concerned with the exploration of the usable subsurface as well as the development of geophysical measurement and evaluation methods. The institute looks back on more than 50 years of experience in geophysical research.
The section Geochronology is specialised in Quaternary geochronology using luminescence and electron spin resonance (ESRElektronenspinresonanz-Datierung Eine physikalische Datierungsmethode, die darauf beruht, daß die Menge magnetischer Anomalien im Probenmaterial proportional zur Lagerungszeit im Sediment ist.) methods. For Blessberg Cave the group is testing thermoluminescence (TL) dating of speleothems, which has a potential to date calcite up to ~2 million years. It is also planned to contribute in dating cave sediments.
