Paleodose of Quartz in Volcano Ash beside Huguang Maar Lake
View through CrossRef
Quartz grains were extracted from volcano ash beside Huguang Maar Lake, and the thermoluminescence (TL) of the grains was measured. Based on the thermoluminescence data of quartz the paleodose of volcanic ash beside Huguang Maar Lake was calculated with sensitized revise technique. The calculated TL dose depending on TL about 315◦C is 75.3±4.8Gy, while the calculated dose depending on TL about 407◦C is 115±8Gy. A physical model is set up to analyze the difference of the two calculation doses, and it can be seen that the latter is relatively veracious.
