Results demonstrate that climate fluctuations recorded by the two boreholes correspond to the marine oxygen isotope stages. Thick layer of coarser grained fluvial deposits and the third layer of "hard mud" were deposited in the study area during MIS 6, reflecting a cold climate. The sediments became fine-grained and indicate a coastal marsh depositional environment during MIS 5. The second layer of "hard mud" was deposited during MIS 4. Fine-grained coastal marsh deposits dominated in the study area during early MIS 3, while lagoon-beach ridges prevailed during middle and late MIS 3, forming a layer of silt and fine sand in the coastal plain. The MIS 2 strata are composed of a typical sedimentary sequence with coarse grain in the lower section and fine grain in the upper section, i. e. yellowish grey or brownish yellow silt and brownish yellow or dark green "hard mud", respectively.
研究结果显示,两孔记录的古气候波动可与深海氧同位素曲线进行对比:对应于深海氧同位素曲线第6阶段(MIS6),堆积厚层的河道相粗颗粒沉积及第3硬土层,反映当时气候寒冷;第5阶段(MIS5),为滨海湖沼沉积,沉积物的颗粒显著变细;第4阶段(MIS4),本区形成第2硬土层;第3阶段(MIS3)的早期,本区也发育滨海湖沼沉积,中晚期则形成潟湖—砂坝体系,在滨海平原区普遍发育粉、细砂层;第2阶段(MIS2),地层由下粗上细的沉积序列构成,下部为黄灰、棕黄色粉砂,上部则为棕黄色或暗绿色硬粘土。

The lithologic characters changed from fluviolacustrine sandstone to aeolian Red Clay with thin interval of greyish-white sand layers at the depth of 602 m. It can be inferred from the rock strata and age that the development age of aeolian sequence in Lanzhou area was 7 Ma at least, which is in accordance with the bottom age (7~8 Ma) of the aeolian sequence of the eastern and central Loess Plateau, suggesting that their accumulation processes are unitary.
皋兰山剖面深度602 m处出现由河湖相砂岩向以风成红粘土为主常夹有薄层砂岩的地层转变,通过岩性地层及年代的推断,兰州地区的风尘序列堆积发育的年代至少为7 Ma,与黄土高原风尘序列堆积底界8~7 Ma基本一致,说明了兰州地区与黄土高原在风尘序列堆积过程中具有统一性。

Xiaozhongdian Basin is a NNW-directed fault depression basin which was shaped while the Qinghai-Tibet Plateau intensely upheaved since the end of the Pliocene epoch, where the lacustrine clay of the middle and late Pleistocene is well distributed from the Xiaozhongdian River section.
滇西北小中甸盆地是上新世末期以来在青藏高原强烈隆起过程中形成的NNW向第四纪断陷湖盆地,从深切的小中甸河谷剖面可见盆地上部发育中晚更新世湖相粘土。
