英文摘要 | The Mg/Sr ratio in a stalagmite, which is directly proportional to D-Mg/Ca, the solid-liquid distribution coefficient of Mg, is proposed as a geochemical thermometer to estimate paleotemperature changes. The paleotemperature change in eastern Beijing over the past 3000 years has been reconstructed by using this thermometer in the stalagmite ZFFS-1 from Jingdong Cave. The records can be divided into two periods: 3000-2000 aBP, cool and wet, the air temperature averaging 9.8degreesC; and 2000 aBP-present, hot and dry, the air temperature being 1degreesC higher than the mean value (11.7degreesC) of the past 3000 years. During 500-200 aBP, the air temperature was about 1.2degreesC lower than that of the present, corresponding to the Little Ice Age in Europe. Like delta(18)O and delta(13)C, Mg/Sr (or D-Mg/Ca) reflects an obviously warming trend of the past 200 years. These results are supported by historic records. |
