Knowledge about changes of regional carbon density during late Quaternary is of great significance for understanding regional and global carbon *** the Hunshandake Sandy Land,located in eastern Inner Mongolia of china as an example,this paper aims to reconstruct Late Quaternary environmental changes,and then to discuss the fluctuations of organic carbon density and storage in the desert environment of northern *** study area with a mean annual precipitation ca.300 mm is characterized by the occurrence of fixed and semi-fixed sand dimes reaching a maximal height of 30 *** research methods included field observations,examinations of grain sizes,as well as carbon and calcium carbonate contents of the sediment *** chronology is based on Optically Stimulated Luminescence(OSL) dating and radiocarbon *** work reveals that the organic carbon density in the surface layer of the Hunshandake Sandy Land changed between at least 2500 g/m during the Holocene Climatic Optimum and 1500 g/m when aeolian processes *** dune construction was restricted by periglacial processes during the Last Glacial Maximum(LGM).The Holocene Climatic Optimum,indicated by extensive formation of kastanozem soils,occurred between 5 ka and 3 ka in the study *** desertification might cause a 4.%loss of total organic carbon storage within several dozen of years in the study area,a considerable amount of this carbon was re-deposited in the regions of downwind directions.

In northern china,the Late Miocene-Pliocene red clay in the eastern Loess Plateau fills a gap of climate records between the wellknown loess-soil sequences of the last 2.6 Ma and the Miocene loess-soil sequences from the western Loess *** studies indicate that the red clay is also of wind-blown origin,covering the period from～7-8 to～2.6 *** red clay therefore provides a good archive to reconstruct paleoecological succession and paleoclimate *** this study,a palynological investigation was conducted on the late Miocene-Pliocene red clay sequence at Xifeng,central Loess Plateau,which provides new insights into the nature of the evolution of vegetation and climate change from～6.2 to～2.4.*** results show that during this period the central Loess Plateau region was covered mainly by a steppe vegetation, indicating long lasting dry climatic *** vegetational zones were recognized during this *** A(～6.2 to～5.8 Ma) is characterized by a steppe ecosystem;Zone B(～5.8 to～4.2 Ma) is characterized by a significant increase of temperate forest plants,indicating a relatively humid regional climate;Zone C(～4.2 to～2.4.Ma) indicates a typical steppe *** vegetation shift at about 4.5-3.7 Ma,when the temperate forest plants decrease, the vegetation gradually changed to typical grassland and even to desert *** is interpreted to represent a drying *** uplift of the Tibetan Plateau at about 4.5 Ma that resulted in the intensification of the monsoon reversal is thought to have played an important role in this significant ecological ***-latitude cooling may have partially contributed to the climate shift during～4.5 to～3.7 Ma in the Loess Plateau region,and most likely was the driving force for the ecological shift at about 3.7 Ma.

Based on an analysis of the fractal structures and mass transport mechanism of typical shear-fluid-ore formation system, the fractal dispersion theory of the fluid system was used in the dynamic study of the ore formation system. The model of point-source diffusive illuviation of the shear-fluid-ore formation system was constructed, and the numerical simulation of dynamics of the ore formation system was finished. The result shows that: (1) The metallogenic system have nested fractal structure. different fractal dimension values in different systems show unbalance and inhomogeneity of ore-forming processes in the geohistory. It is an important parameter to symbolize the process of remobilization and accumulation of ore-forming materials. Also it can indicate the dynamics of the metallogenic system quantitatively to some extent. (2) In essence, the fractal dispersive ore-forming dynamics is a combination of multi-processes dominated by fluid dynamics and supplemented by molecule dispersion in fluids and
