Results Xunhua-Guide area is characterized by step-shaped low-relief at different elevation. The low-relief surfaces developed above the newer strata in sedimentary basin among the Oligocene to the lower Pleistocene are in higher elevation, but above the older strata, are in lower elevation. The elevations of all above low-relief surfaces are lower than those of the planation surface above the bedrocks in the thrust belts. The low-relief surfaces of terraces, developed on both sides of the deep-cutting valleys within the basins, are lowest in elevation.

结果 循化－贵德地区地形形态总体呈台阶状结构，在不同海拔高度存在低起伏地形；发育于盆地沉积地层之上的低起伏面表现为年代越新的地层之上低起伏面高程越高，越老的地层高程越低，并且它们均低于发育于逆冲带基岩之上的夷平面；发育于盆地深切河谷两侧阶地之上的低起伏面海拔高程总体较低。

Recent developments in the research on the geology and geochemistry of the newly-discovered clayey breccias at the lop of the Xiaochaka Formation in the Juhuashan, Xiaochaka and Shishuihe areas, Qiangtang Basin, northern Tibet have disclosed that mineral compositions, textures and structures, occurrences and sectional architectures of the clayey breccias agree well with those of the paleo-weathering crust in these areas. Compared with the bedrocks, the paleo-weathering crust is characterized by the leaching out of CaO and CO2, and relative enrichment of SiO2, Al2 O3, Fe2O3, K2O, Na2O, MnO and P2O5. The clayey weathered residues in the paleo-weathering crust are characterized by marked enrichment of REEs, much higher contents of LREEs than those of HREEs, markedly positive Ce anomalies and negative Eu anomalies, and a noticeable increase in other element contents besides Mo, Sn and U from the clayey weathered residues.
