Measurements of the 36Cl/10Be ratio in the deep ice of Talos Dome (East Antarctic): applications to paleomagnetism and ice dating. Open
Cosmogenic nuclides such as beryllium-10 (10Be) and chlorine-36 (36Cl) are valuable tools for dating deep ice cores and reconstructing paleomagnetic events. These nuclides are formed through interactions of target atoms in the atmosphere w…
