| 摘 要： | 对岱海西南部湖滨地区（40°32.127′N,112°37.802′E）钻取的一根长79.16m的高取芯率（98.8%）沉积岩芯（DH06A）进行了高分辨率的湖泊沉积物磁学性质测量。对U型槽法和常规散样方法得到的磁化率和非磁滞剩余磁化强度测量结果进行了系统的比较。

| Abstract: | High-resolution magnetic measurement on lake sediments from arid and semi-arid regions is an important means of characterizing paleoenvironmental changes. Previous research has shown that the Daihai Lake, an inland graben-type basin in Inner Mongolia, China, contains rich information about the evolution of paleomonsoons. Here we present results of high-resolution magnetic measurements of the lake sediments from a 79.16m core(DH06A), drilled at the southeast littoral area of the Daihai Lake(40°32.127′N, 112°37.802′E). |
