建立地层年龄序列是恢复和重建古地理环境的重要手段之一.从湖相纹泥到210Pb,137CS和14C等方法的应用,对建立不同地质体形成年代有了相应的测年方法.但不同方法对测试材料和测年范围有其特殊要求.在现代风沙作用强烈的荒漠地区,寻找符合上述方法的测年材料较为困难,而塔克拉玛
The establishment of stratigraphic age sequence is one of the most important means to recover and reconstruct paleogeography.The application of 210Pb, 137CS and 14C methods from lacusle facies to the formation of different geological bodies has corresponding dating methods, but different The method has its own special requirements for the test materials and the dating range.In the desert area where the modern sandstorm is strong, it is more difficult to find the dating materials that meet the above methods, while the Taklimak
