Abstract: It made the tracers of debris flows by using thermoluminescence (TL) technique in simulated experiments. The luminescence mechanism of guide sample was studied through those experiments, including the material selection of the guide sample and ascertain of granularity and quality when making samples, etc. It described the procedure of how to make guide samples, including the homogeneity test of guide sample, outliers test and valuation of guide samples. The results provide a series of scientific and practical method for making high quality geological guide samples with the luminescence method.
