The Late Cenozoic basins in the Weihe-Shanxi Graben, North china Craton are delineated by northeast-striking faults. The faults have, since a long time, been related to the progressive uplift and northeastward expansion of the Tibetan Plateau. To show the relation between the basins and faults, two Pliocene-Pleistocene stratigraphic sections （Chengqiang and Hongyanangou） in the southern part of the Nihewan Basin at the northernmost parts of the graben are studied herein. Based on the sedimentary sequences and facies, the sections are divided into three evolutionary stages, such as alluvial fan-eolian red clay, fan delta, and fluvial, with boundaries at -2.8 and -1.8 Ma. Paleocurrent indicators, the composition of coarse clastics, heavy minerals, and the geochemistry of moderate-fine clastics are used to establish the temporal and spatial variations in the source areas. Based on features from the middle- northern basin, we infer that the Nihewan Basin comprises an old NE-SW elongate geotectogene and a young NW-SE elongate subgeotectogene. The main geotectogene in the mid-north is a half-graben bounded by northeast-striking and northwest-dipping normal faults （e.g., Liulengshan Fault）. This group of faults was mainly affected by the Pliocene （before -2.8-2.6 Ma） NW-SE extension and controlled the deposition of sediments. In contrast, the subgeotectogene in the south was affected by northwest-striking normal faults （e.g., Huliuhe Fault） that were controlled by the subsequent weak NE- SW extension in the Pleistocene. The remarkable change in the sedimentary facies and provenance since -1.8 Ma is possibly a signal of either weak or strong NE-SW extension. This result implies that the main tectonic transition ages of -2.8-2.6 Ma and -1.8 Ma in the Weihe-Shanxi Graben are affected by the Tibetan Plateau in Pliocene-Pleistocene.

The detailed magnetic susceptibility anisotropy study on the sediments of two sections, which are located in the lake-center and the lakeshore of the Huangqihai Lake, Inner Mongolia, revealed their hydrodynamics and sedimentary environment changes in the recent 2000 years. The results show that the sediments of two sections both display normal depositional magnetic fabrics, of which the minimum susceptibility axes （K3） are oriented perpendicular to the bedding plane and the maximum magnetic susceptibility axes （K~） lie parallel with the bedding plane. In addition, the iakeshore presents higher magnetic anisotropy degree （P）, magnetic foliation （F） and current factor （F~） than the lake-center, showing that the lakeshore has higher flow velocity. For the west Huangqihai Lake （HQW） section in the lake-center, the magnetic matrix grain degree （Q） and the inclination of the minimum susceptibility axes sharply increased and decreased, respectively, at a depth of about 10 cm, 24 cm, 45 cm and 74 cm, which indicate abnormal depositional events with strong kinetic energy. Through comparative analysis, the HQW section can be divided into three stages from top to bottom. The upper stage was a stable depositional environment with strong hydrodynamic energy and low water level, which shows relatively higher Fs value and the Q value varies similarly with P and F. The middle stage was a stable depositional environment with high water level and low hydrodynamic energy, intermitted with high-energy abnormal events, which shows relatively lower Fs and the Q value was negatively correlated with P and F. The lower stage was an unstable depositional environment with low hydrodynamic energy and high water level, which shows relatively lower P, F, and F~ value.

植被中C_(4)植物比例与气候条件和生态系统类型密切相关,了解C_(4)植物扩张历史对于理解过去生态系统格局演化以及古气候变化具有重要科学意义。本研究在已有古地磁年代基础上,通过对泥河湾盆地郝家台NHA钻孔224.2~175.4 m段内243个沉积物样品的碳酸盐δ13C分析,结合δ18O、地球化学元素、粒度等环境代用指标测试,揭示了泥河湾盆地上新世3.66~2.89 Ma期间的C4植物扩张历史。研究结果显示:1)泥河湾盆地3.66~2.89 Ma期间,δ13C均高于-7‰,且δ13C值整体呈现波动上升的趋势,指示了研究时段内泥河湾盆地C3、 C_(4)植物共存,C_(4)植物总体呈现出明显扩张的趋势,其中约3.58 Ma和约3.10 Ma为研究时段内两次最为明显的C_(4)植物扩张重要时间节点;2)3.58 Ma之前,δ13C多低于-5‰,植被以C_(3)植物为主,3.58~3.10 Ma期间δ13C含量在-5‰至-3‰之间波动,气候趋向干旱化方向发展,C_(4)植物所占比例有所增加;3)3.10 Ma之后的全球性冷干事件导致泥河湾盆地气候显著变冷变干,尤其是干旱化程度显著增强,δ13C多高于-3‰,指示泥河湾盆地C_(4)植物出现显著扩张,以C_(4)植物为主的草本植被占比可能超越C_(3)植物,成为区域主要的植被类型;4)C_(4)植物扩张过程中,也存在数次波动,如在约3.46 Ma、约3.38 Ma、约3.28 Ma和约3.13 Ma等时段内出现数次持续时间较短的δ13C明显低值,分别可以与全球深海氧同位素阶段(MIS)明显冷时期对应的MG6、 MG4、 M2和KM2相一致,但这些低值呈现出随时间推移,δ13C值逐渐升高的趋势,显示C4植物的影响逐渐加强。
