摘要： The solution chemistry of forested streams primarily in western North America is explained by considering the major factors that influence this chemistry-geological weathering;atmospheric precipitation and climate;precipitation acidity;terrestrial biological processes;physical/chemical reactions in the soil;and physical, chemical, and biological processes within streams. Due to the complexity of all these processes and their varying importance for different chemicals, stream water chemistry has exhibited considerable geographic and temporal variation and is difficult to model accurately. The impacts of forest harvesting on stream water chemistry were reviewed by considering the effects of harvesting on each of the important factors controlling this chemistry, as well as other factors influencing these impacts - extent of the watershed harvested, presence of buffer strips between streams and harvested areas, nature of post-harvesting site preparation, revegetation rate following harvesting, pre-harvesting soil fertility, and soil buffering capacity. These effects have sometimes reinforced one another but have sometimes been counterbalancing or slight so that harvesting impacts on stream water chemistry have been highly variable. Eight major knowledge gaps were identified, two of which - a scarcity of detailed stream chemical budgets and knowledge of longitudinal variation in stream chemistry - relate to undisturbed streams, while the remainder relate to forest harvesting effects.

摘要： Sampled outcrops of Permian coal seams of the Bainmedart Coal Measures in the Lambert Graben, eastern Antarctica, have been analysed for their proximates, ultimates, ash constituents and trace elements. A similar series of samples has been analysed for their principle maceral and microlithotype components and vitrinite reflectance, The coals are sub-bituminous to high volatile bituminous in rank;maturity increases markedly in southern exposures around Radok Lake where the oldest pan of the succession is exposed and some strata have been intruded by mafic dykes and ultramafic sills, The coal ash is mostly silica and aluminium oxides, indicating that the mineral ash component is mostly quartz and various clay minerals, The ratio of silica to aluminium oxides appears to increase in an upward stratigraphic direction, The coal macerals include a relatively high liptinite content (mainly sporinite) that is significantly higher than for typical Gondwana coals. Greater degrees of weathering within the floodbasin/peat mire environments associated with climatic drying towards the end of the Permian might account for both preferential sporopollenin preservation and increased silica:aluminium oxide ratios up-section. Correlation of the coat maceral components to adjacent peninsula India coals indicates the closest comparative coals of similar age and rank occur within the Godavari Basin, rather then the Mahanadi Basin, which is traditionally, interpreted to have been contiguous With the Lambert Graben before Gondwanan breakup. The petrological characteristics suggest that either previous interpretations of Palaeozoic basin alignments between Antarctica and India are incorrect, or that environmental settings and post-Permian burial histories of these basins were strongly independent of their tectonic juxtaposition. A permineralized peat bed Within file Succession reveals that the coals predominantly comprise wood- and leaf-rich debris derived From low-diversity forest-mire commu
