| 1 | The origin and provenance of Malan loess along the eastern margin of Qinghai-Xizang (Tibetan)Plateau and its adjacent area显示文摘A preliminary study of the Malan loess on the eastern margin of the Qinghai-Xizang(Tibetan)Plateau and its adjacent area shows that along the boundary of Kunlun Mts.-Buqing Mts.-A’nymaqnMts.-South Qinling(Motianling),the Malun loess falls roughly into two main depositional regions:to itsnorth,a hot loess region in which dusts come mainly from the Asian inland arid area;to its south,a coldloess region in which dusts come chiefly from the Qinghai-Xizang Plateau.The possible causative fac-tors and processes for the loess difference are the uplift of the Plateau and the effects of its resultant particuolar landform,the interactions of its induced Asian monsoon,by-flowing westlies and plateau monsoon,and thedifference of sediments of source areas. | 方小敏 | 1995 | Science China Chemistry1995，38，7： | 13 |
| 2 | Climatic and environmental changes over the last millennium recorded in the Malan ice core from the northern Tibetan Plateau显示文摘In this paper, climatic and environmental changes were reconstructed since 1129A.D. based on the Malan ice core from Hol Xil, the northern Tibetan Plateau. The record of δ 18O in the Malan ice core indicated that the warm-season air temperature variations displayed a general increase trend, the 20th-century warming was within the range of natural climate variability, and the warmest century was the 17th century while the warmest decade was the 1610s, over the entire study period. The “Medieval Warm Epoch” and “Little Ice Age” were also reflected by the ice core record. The dust ratio in the Malan ice core is a good proxy for dust event frequency. The 870-year record of the dust ratio showed that dust events occurred much frequently in the 19th century. Comparing the variations of δ 18O and the dust ratio, it is found that there was a strong negative correlation between them on the time scales of 101―102 years. By analyses of all the climatic records of ice cores and tree rings from the northern Tibetan Plateau, it was revealed that dust events were more frequent in the cold and dry periods than in the warm and wet periods. | WANG Ninglian1,2, YAO Tandong2,1, PU Jianchen1, ZHANG Yongliang1 & SUN Weizhen1 1.

| 3 | RARE EARTH ELEMENTS IN THE MALAN LOESS FROM THE MIDDLE REACHES OF THE HUANGHE RIVER显示文摘Loess of China, especially the Malan loess distributed along the middle reaches of the Huanghe River, has attracted great attention of many geologists throughout the world because of its extensive occurrence and close relation with the living environment of mankind. As the Malan loess was formed relatively late, and thus has not been affected by hysterogenic diagenesis, it has well preserved the primary characteristics at the time of | 吴明清 文启忠 潘景瑜 刁桂仪 | 1991 | Chinese Science Bulletin1991，36，16： | 7 |
| 4 | The Cosmic Dusts in the Malan Loess Near Xi' an显示文摘The Quaternary loess deposits in the arid-semiarid area in northwestern China are composed of eolian sedimemts which are continuous in terms of sedimentation and have undergone little alternation after deposition.They provide an ideal place for the preservation of the extraterrestrial falls on the earth.The Late Pleistocene Malan loess is chosedn for our study of the preserved cosmic dusts. | 赵济湘 肖永林 祝一志 | 1994 | Chinese Science Bulletin1994，39，24： | 0 |
