1Minimum Bedrock Exposure Ages and Their Implications:Larsemann Hills and Neighboring Bolingen Islands,East Antarctica显示文摘可观的争吵在广泛的冻结成冰是否在 Larsemann 山发生在全球上次冰川的最大值(LGM ) 期间上存在。在这研究,我们使用在里面 situ 生产了 cosmogenic 核种 10Be (半生活 1.51 妈) 提供最小的暴露年龄让六件基岩样品和一块乖僻的大石头以便在 Larsemann 山并且在附近的 Bolingen 岛上决定冰川的消失的最后时期。从友谊山拿的三件基岩样品(镜子半岛上的最高的山峰, Larsemann 山;从冰表的 2 km ) 有最小的暴露年龄从 40.0 ~ 44.7 ka 。从山峰 106 的乖僻的大石头(就在冰表的边) 有仅仅 8.8 ka 的更年轻的最小的暴露年龄。为从 Blundell 的二件基岩样品的最小的暴露年龄达到顶点(Stornes 半岛上的最高的山峰, Larsemann 山;从冰表的 2 km ) 是大约 17 和 18 ka。在 Bolingen 岛上(西南到 Larsemann 山;从冰表的 10 km ) ,为一件基岩样品的最小的暴露年龄在友谊山类似于那(即, 44 ka ) 。我们的结果显示在 Larsemann 山并且在附近的 Bolingen 岛上的基岩暴露在全球 LGM 前显然开始了(即, 2022 ka ) ,并且在南极海岸区域的基岩侵蚀率可能显然比在内部陆地高。HUANG Feixin LI Guangwei LIU Xiaohan KONG Ping JU Yitai David FINK FANG Aimin YU Liangjun 2010Acta Geologica Sinica(English Edition)2010,84,3:2
2Cenozoic terrestrial palynological assemblages in the glacial erratics from the Grove Mountains, east Antarctica显示文摘Fossiliferous glacial erratics have been found in moraines of the Grove Mountains, east Antarctica since 1998 by Chinese National Antarctic Research Expedition (CHNARE) teams. These erratics were derived from a suite of glaciogene strata hidden beneath the Antarctic Ice Sheet in the Lambert glacier drainage system, and thus provide a record of Cenozoic paleoenvironmental conditions and fossil biotas that are so far unknown from outcrops and drill cores in this region. By microfossil analysis, sparse Neogene spores and pollen grains are revealed, including: Toroisporis (Lygodiaceae), Granulatisporites (Pteridaceae?), Osmunda (Osmundaceae), Polypodiaceae, Magnastriatites (Parkeriaceae), Deltoidospora, Araucariaceae, Taxodiaceae, Podocarpus (Podocarpaceae), Dacrydium (Podocarpaceae), Pinus (Pinaceae), Keteleeria (Pinaceae), Picea (Pinaceae), Tsuga (Pinaceae), Chenopodiaceae, Artemisia (Asteraceae), Asteraceae, Gramineae, Fraxinoipollenites (Oleaceae), Oleoidearumpollenites (Oleaceae), Oleaceae, Operculumpollis, Nothofagidites (Nothofagus), Rhus, Quercus (Fagaceae), Juglans (Juglandaceae), Pterocarya (Juglandaceae), Liquidambar (Hamamelidaceae), Ulmus (Ulmaceae), Ulmoidepites (Ulmaceae), Tilia, Proteacidites (Proteaceae) and Tricolpopollenites; but without any marine diatoms. Most of the spores and pollen grains in the erratics are considered to originate from local sources except for some older exotic components that might be recycled from the basement sedimentary rocks by the ice sheet, so they are in situ sporo-palynological assemblages. Furthermore, since the source areas of the glaciogenic sedimentary rocks are assumed to be local or in the up glacier areas, the palynological assemblages in these erratics represent an inland terrestrial flora during a warmer period of the ice-sheet evolutionary history. The ages of these erratics are also discussed based on the occurrence of some diagnostic pollens such as the Artemisia, Chenopodiaceae and Nothofagus, which implies Neogene (most probably Pliocene). As a preliminary conclusion, we think that the existence of the Cenozoic glaciogenic rocks and their palynological assemblages present new evidence for a large scale glacial retreat event in the Grove Mountains of east Antarctica, and thus support a dynamic East Antarctic Ice Sheet (EAIS). Furthermore, the absence of marine fossils in the samples analyzed not only provides additional evidence for a terrestrial sedimentary environment of these erratics, but also indicates that there is no transportation of Cenozoic marine fossils from the adjacent areas of the Grove Mountains.Aimin Fang Xiaohan Liu Weiming Wang Feixin Huang Lianjun Yu 2009Progress in Natural Science:Materials International2009,19,7:2
3Preliminary investigation of rubidium distribution in the Grove Mountains area, East Antarctica显示文摘We analyzed rock samples from the Grove Mountains in Antarctica to determine the distribution of rubidium (Rb) in that location. We collected samples from the Black Nunataks, Melvoldt Nunataks, Mason Peaks, Zakharoff Ridge, Mount Harding, and the northern Gale Escarpment. Geochemical analysis indicated that in some samples the amount of Rb was higher than 300 ppm. This suggests that rocks from the Grove Mountains are rich in Rb. Based on field observations and previous research, we speculate that mica and potash feldspar from moyite, granite gneiss, and felsic pegmatite are the primary carrier minerals of Rb. However, further research is necessary to confirm this speculation.LI Yan HUANG Feixin 2018Advances in Polar Science2018,29,2:1
