Abstract
We present results of the determination of36C1 (T 1/2=3.0·105a) in rock samples produced in situ by cosmic rays and natural radioactivities. These experiments were designed to determine the feasibility of using36Cl for studying erosion processes in calcium rich minerals like limestone or dolomite. The36Cl/Cl ratios in the samples have been determined with accelerator mass spectrometry (AMS) at the Munich accelerator laboratory. A first application is the investigation of the erosion in the last million years in Allchar (Yugoslavia) for the feasibility study of the geochemical205Tl solar neutrino experiment.
