Recent progress of Be-10 tracer studies in Chinese loess
Studies of cosmogenic Be-10 in Chinese loess began about twenty-five years ago and since then a number of research groups worldwide have contributed to a firm understanding of the production, transport, deposition and storage of Be-10 in loess. The essential characteristics that make Be-10 a useful...

Studies of cosmogenic Be-10 in Chinese loess began about twenty-five years ago and since then a number of research groups worldwide have contributed to a firm understanding of the production, transport, deposition and storage of Be-10 in loess.
