中文摘要：

蓝田盆地新生代时期地层以蕴含丰富的哺乳动物化石而备受关注，尤其是公王岭和陈家窝第四纪黄土地层中曾经分别发掘出了蓝田猿人头骨和下颌骨化石．基于过去对中国北方黄土高原第四纪黄土的深入研究，针对本区沉积物的磁性地层的研究似乎变得相对容易．但由于蓝田盆地毗邻秦岭北麓，区域构造地貌发育，第四纪风成沉积序列发育常常并不完整，这给特定剖面的详细定年工作会造成一定困难．在现阶段针对本区地层研究普遍缺少绝对定年的材料和方法的情况下，对部分记录了相对较完整的黄土一古土壤旋回的代表性剖面（如段家坡剖面、渭南剖面）的研究以及借助于其它替代性指标对古气候演变历史的反演将有助于蓝田盆地第四纪地层序列的横向对比和划分，这对于诸多哺乳动物化石群年代的精确研究具有重要的意义．

英文摘要：

Much attention has been paid to the Cenozoic strata of the Lantian Basin abundant in mammalian fossils, particularly in loess strata of Gongwangling and Chenjiawo, where the fossil cranium and mandible of Lantian Man were found. It seems that the magnetostratigraphic research of Quaternary sediments in this area should be very easy on the basis of previous good work of the Quaternary loess on the Chinese Loess Plateau. But the incomplete sequence of Quaternary aeolian sediments in the Lantian Basin, largely due to its lying in the north piedmont of the Qinling Mountains and the complex tectonic geomorphology of this area, makes it difficult to date specific stratigraphic sections. Thus, the stratigraphic research of this area usually lacks absolute dating materials and methods. Therefore, investigations of typical stratigraphic sections with relatively complete loess-paleosol sequence, such as the Duanjiapo section and Weinan section, and reconstruction of the paleoclimate of this area with other proxy indicators, are very helpful to comparison and classification of the Quaternary strata in the Lantian basin, and thus of great importance to accurate dating of mammalian fauna fossils.
