| 摘 要： | 在中欧地区的河谷、洪积扇、山坡坡麓及湖底常零星分布着更新世及全新世的碳酸盐沉积物。不少学者把碳酸盐沉积当作气候变化的产物并划分出其在中欧沉积的若干时期。笔者通过德国中部Leine河流域新老石灰泉华的详细研究对泉华沉积与气候直接联系的观点提出了新的见解。运用不同方法测年验证，得知研究区的石灰泉华沉积始于11000aB.P,随后石灰泉华在研究区不同地点连续沉积。岩芯上沉积的变化和石灰泉华层的消失应是由地貌过程所引起的泉水出露位置改变所致。

| Abstract: | Pleistocene and Holocene freshWater carbonate is often scattered in valleys, on alluvial fans, at the foot of mountain slopes and the bottom of lakes in Central Europe. Since the beginning of this century, a large number of different names have been given to this kind of deposit, such as sinter, calc-sinter, travertine, tufa or calctufa, Sinterkalk, Wiesenkalk, Dauch and Quellkalk. Fundamentally all the different terms are used in a general meaning as well as in more restricted contexts to distinguish between different freshwater carbonate deposits on grounds of porosity,genesis and location. Quite a few researchers have used carbonate deposits as paleoclimatic indication and have divided into many different episodes for these deposits, in Central Europe.In order to clarify the mechanism of carbonate deposition in the maritime climate zone of Central Europe, the authors have made detailed investigations into calc- sinters in the area of Leine River (southern forer Saxony, Germany). Many drillings have presented sinters with a thickness commonly between 5 cm and 150 cm. |
