| 1 | Discovery of Quaternary glacial evidence of Snow Mountain in Taiwan, China显示文摘There are glacial remains of three different periods on the main peak of Snow Mountain in Taiwan province, including cirque lake, crosswall, polished surface, striation, moraine ete. These three different periods were called, respectively, Shanzhuang ((44.25 ± 3.72) kaBP), Shuiyuan ((18.26 ± 1.52) kaBP), and Xueshan glacial stages (the late period of last glaciation). it is characterized by the earlier glacier broad in scale. | CUI Zhijiu YANG Jianfu LIU Gengnian WANG Xin SONG Guocheng | 2000 | Chinese Science Bulletin2000,45,6: | 20 |
| 2 | Discovery and character of the Kunlun-Yellow River Movement显示文摘Based on geomorphological, tectonic and sedimentary data, a Kunlun Yellow River Tectonic Movement has been recognized in 1 10-0 60 Ma B.P. This tectonic movement, which leads to uplift of the Qinghai_Xizang (Tibet) Plateau from 1 500 to 3 000-3 500 m, is periodic, abrupt and changeable in the movement rate of uplifting and slide slipping. | CUI Zhijiu 1, WU Yongqiu 2,3 and LIU Gengnian 1 1.

| 3 | Much late onset of Quaternary glaciations on the Tibetan Plateau:determining the age of the Shishapangma Glaciation using cosmogenic 26Al and 10Be dating显示文摘The onset of Quaternary glaciations is a critical event in the climate and tectonic history of the Tibetan Plateau.The Shishapangma Glaciation,defined based on the till deposit from the northern slopes of Mt.Shishapangma,has been identified as the oldest glaciation on the Tibetan Plateau.However,the timing of this glaciation has not been constrained.We measured^(10)Be and^(26)Al concentrations of a set of boulders on top of this till and simulated their complex exposure-burial histories.The simulated results indicate that the formation age of this till is likely around 835.2±241.0 ka,representing the minimum timing of glacial onset on the Tibetan Plateau.The Shishapangma Glaciation is apparently much younger than the glacial onset in many other areas of the world,such as Europe and North America,and was likely driven by the coupled effect between tectonic uplift and climate cooling during the early–middle Pleistocene transition. | Yixin Chen Yingkui Li Mei Zhang Zhijiu Cui Gengnian Liu | 2018 | Science Bulletin2018,63,5: | 7 |
| 4 | Comments on the planation surface once more显示文摘The authors reviewed the research of planation surface in recent years and commented on the development of method and theory about the planation surface. Some aspects of research, such as the restrictive planation surface, the karst planation surface, the fossil planation surface, the dating of weathering crust, the research of weathering crust and environmental evolution, extremely enriched the method and theory of the planation surface. Besides, the authors pointed out that we must take further steps to study the following issues: the deformation of planation surface, the original height of planation surface, the recognition and contrast of the planation surface. The weathering crust and planation surface should be regarded as a whole, and it will still be a principal aspect in the future. | CUI Zhijiu LI Dewen FENG Jinliang LIU Gengnian | 2002 | Chinese Science Bulletin2002,47,10: | 4 |
| 5 | Comment on planation surface显示文摘Planation surfaces includes peneplain, pediment and etchplain, which differ from each other in formation and distribution. The double leveling surfaces theory offered by Budel can be used to explain the landforms in limestone areas. According to Budel, that the residue is the upper layer of a planation surface is very important in studying the formation | Zhiju Cui Dewen Li Yongqiu Wu Gengnian Liu | 1999 | Chinese Science Bulletin1999,44,22: | 3 |
| 6 | Characteristics of the subglacially-formed debris-rich chemical deposits and related subglacial processes of Qiangyong Glacier,Tibet显示文摘Subglacially-formed debris-rich chemical deposits were found both on bedrock surface and in bedrock crevice on the edge of Qiangyong Glacier, one of the continental glaciers in Tibet. Grain size distribution, internal structures and chemical components of the chemical deposits were analyzed. It can be inferred that the temperature of some part of the ice-bedrock interface is close to the melting point and there exists pressure melting water under Qiangyong Glacier. Debris, especially those from continental aerosols, can release Ca^++ in the water. At the lee-side of obstacles on glacier bed the CO2 in the melting water might escape from the water and the melting water might refreeze due to the dramatically reduced pressure, making the enrichment and precipitation of CaCO3. The existence of subglacial melting water and the process of regelation under Qiangyong Glacier indicate that sliding could contribute some proportion to the entire movement of Qiangyong Glacier and it belongs to multiolex cold-temperate glaciers. | LUO Risheng, CAO Jim, LIU Gengnian, GUI Zhijiu(College of Environmental Sciences, Peking University, Beijing 100871, China) | 2003 | Journal of Geographical Sciences2003,13,4: | 2 |
| 7 | Global warming accelerates the upfreezing of permafrost in arid middle Tianshan Mountains显示文摘Upfreezing is an important geomorphic process in the periglacial environment.It is a product of cold climate and thus an important part of the cryospheric processes.Based on the long-term positioning observations in the source area of the Urumqi River,this article represents an in-depth discussion of the characteristics of sorted circles and upfreezing mechanisms in the Tianshan Mountains.In the source area of the Urumqi River,the intensity of upfreezing is the highest within the top 25 cm near the surface,while targets with a diameter of 3 cm are least affected by upfreezing.There is no distinct difference between the centre with fine grains and the margin with coarse debris within the same sorted circle in terms of the intensity of upfreezing.The correlation analysis demonstrates that temperature plays an important role in upfreezing and the development of sorted circles.A long-time positioning observation of sorted circles reveals that periglacial landforms are sensitive to regional climate change and respond quickly to the temperature increase of the recent two decades.Enhanced upfreezing was found to be due to increased soil moisture content. | LI ChuanChuan CHEN YiXin NIE ZhenYu CUI ZhiJiu LIU GengNian | 2013 | Chinese Science Bulletin2013,58,31: | 2 |
| 8 | Processes and environmental significance of the subglacial chemical deposits in Tianshan Mountains显示文摘On the bedrock surface of Glacier No.1 in the headwater of Urumqi River, Tianshan Mts., well layered and crystallized subglacial calcite precipitations were discovered. Based on observations and analysis of the surface form, sedimentary texture and structure, and chemical composition of the deposits, clues about the subglacial processes and environment are deduced. The radial-growth crustation texture of the deposits, which builds up in the saturated CaCO3 so- lution, proves the existence of pressure melting water and water films under Glacier No.1; and their rhythmic beddings, dissolved planes and unconformable contacts show that the water films responsible for the formation of these structures were in a wide range of spatial as well as tem- poral variations. Though formed under continental glacier in non-limestone area, the deposits are quite similar to those formed under temperate glaciers in limestone areas, a fact that shows a similar process of chemical precipitation between the two. Hence the enrichment of calcium in the subglacial melting water and the process of precipitation have actually little to do with the bedrock lithology and the glacier types. The cemented detritus in the deposits are rich in Fe and Al while depleted in K, Na and Si; also the included clay mineral consists mainly of illite, which reveals some weak chemical weathering under the continental glacier. The subglacial CaCO3 precipitates when plenty of Ca++ melt into the subglacial melting water on a comparatively en- closed ice-bedrock interface under a high CO2 partial pressure, the forming of subglacial chemical deposits therefore offers unequivocal evidence for the ongoing of subglacial chemical reactions. | LIU Gengnian LUO Risheng CAO Jun CUI Zhijiu | 2005 | Science China Earth Sciences2005,48,9: | 2 |
| 9 | Mineral deformation and subglacial processes on ice-bedrock interface of Hailuogou Glacier显示文摘Hailuogou Glacier is located in a warm and humid maritime environment. It is large and moves very fast. The bottom of the glacier slides intensively and the temperature at the bottom approaches the pressure melting point. Therefore, there are abundant melting water and debris which act as effective 'grinding tools' for glacial abrasion. Polarizing microscope is used to observe the mineral deformation characteristics on the ice-bedrock interface. It is found that feldspar, quartz, hornblende and biotite are exposed to deformation, fracture and chemical alteration to various extents. Bending deformation is common for biotite, due to their lattice characteristics, and the bending orientations are mostly the same as the glacier flow. Bending deformation also occurs in a few hornblendes. High-angle tension fracture and low-angle shear fracture are common for quartz and feldspar, some of them are totally crushed (mylonizations) due to their rigidity. Thus, all the abrasion, quarrying, subglacial water action and subglacial dissolution processes at the bottom of the glacier are verified at the micro-scale level. Mineral deformation and fracture are the basic subglacial erosion mechanisms. The abrasion thickness is 30―90 μm for each time and the average is 50 μm. Most of the debris are silt produced by glacial abrasion. The extent of mineral deformation and fracture decreases drastically downwards beneath the bedrock surface. The estimated erosion rate is about 2.2―11.4 mm/a, which is similar to that of other maritime alpine glaciers, smaller than that of large-scale piedmont glaciers in Alaska (10―30 mm/a), and larger than that of continental glaciers (0.1―1.0 mm/a). The type and size of a glacier are the main factors that influence its erosion rate. | LIU GengNian CHEN YiXin ZHANG Yue FU HaiRong | 2009 | Chinese Science Bulletin2009,54,18: | 1 |
