摘要:
ABSTRACTA population of stones moving under seasonal snow creep down the backwall of a shallow glacial cirque in the Snowy Mountains, Australia, was sampled on a stratified random plan. On this basis the weight of the total population was estimated for combination with movement measurements over the 1963–1975 winters to determine an annual transport rate of 15 t/m/km2/y, resolvable into a vertical drop of 6.6 t/m/km2/y and a horizontal shift of 13.5 t/m/km2/y. Compared with the rates determined by Rapp for different slope processes in Swedish Lapland this is slow. This process may be better developed in mid-latitudes than in high latitudes as a result of more rapid firnification.Some measures of nivational striae are given.
