1In-situ cosmogenic ^(36)Cl denudation rates of carbonates in Guizhou karst area显示文摘This study quantifies surface denudation of carbonate rocks by the first application of in-situ cosmogenic36Cl in China. Concentrations of natural Cl and in-situ cosmogenic36Cl in bare carbonates from Guizhou karst areas were measured with isotope dilution by accelerator mass spectrometer. The Cl concentration varied from 16 to 206 ppm. The 36Cl concentrations were in range of (0.8-2.4)106 atom g-1 , resulting in total denudation rates of 20-50 mm ka-1 that averaged over a 104-105 a timescale. The 36Cl-denudation rates showed roughly a negative correlation with the local mean temperature. This preliminary observation may suggest the variations of proportions of chemical weathering and physical erosion in denudation process, depending upon local climatic conditions.XU Sheng LIU CongQiang FREEMAN Stewart LANG YunChao SCHNABEL Christoph TU ChengLong WILCKEN Klaus ZHAO ZhiQi 2013Chinese Science Bulletin2013,58,20:7
2贵州喀斯特地区碳酸盐岩的宇宙成因核素^(36)Cl侵蚀速率显示文摘喀斯特地区侵蚀速率是理解全球碳循环、喀斯特地貌演化以及土地利用等学科的最基本问题之一.侵蚀速率估算方法主要包括:(1)流域河水化学溶解物平衡的计算;(2)置于不同环境下的大理岩片重量损失的观测;(3)显微侵蚀测量仪对暴露地表的直接测量;(4)碳酸盐岩中石英脉的长期观测;(5)地表岩石中宇宙成因核素36Cl(半衰期3万年)的测定.与其他方法相比,地表岩石中36Cl含量反映了104-105年尺度内的岩石暴露和侵蚀历史.徐胜 刘丛强 FREEMAN Stewart 郎赟超 SCHNABEL Christoph 涂成龙 WILCKEN Klaus 赵志琦 2013科学通报2013,58,19:2
