The influence of hillslope gradient, regolith texture, stone size and stone position on the presence of a vesicular layer and related aspects of hillslope hydrologic processes: a case study from the Australian arid zone
This paper aims to determine the influence of slope gradient, regolith texture, stone size, and depth of stone embedment on the presence of a vesicular layer just below the surface in arid Australia. The study also identifies the role
Archéologie préhistorique et processus de formation des stones-lines en Afrique centrale (Congo-Brazzaville et zones périphériques)
Les stone-lines étudiées correspondraient à une surface de sol du type pavage datant du Maluekien (70 000-40 000 BP, avec une industrie lithique attribuée au Sangoen), recouverte postérieurement par des matériaux meubles remontés par les termites ou
Stone cover on desert hillslopes: extent of bias in diameters estimated from grid samples and procedures for bias correction
The surface stone mantles typical of dryland hillslopes are the focus of this work. Because the stones on dryland slopes are often only a veneer over finer-textured materials, true volumetric sampling is not possible and any method that is adopted
Thermal response characteristics of stone: implications for weathering of soiled surfaces in urban environments
Soiling of stone surfaces by particulate deposition increases absorption of radiant energy, raises surface/subsurface temperature gradients and accentuates rates of surface temperature change. Short-term fluctuation of raised surface temperatures
, in response to variations in windspeed and cloud cover, may ultimately contribute to stone breakdown through fatigue effects which reduce cohesive strength of intergranular bonds and initiate microfracture development.
Estimating stone and boulder content in forest soils - evaluating the potential of surface penetration methods
This study aims a) to investigate the stoniness (relative volume of stones and boulders) of representative forest soils in central Sweden, b) to evaluate the possibilities to predict soil stoniness with non-destructive surface penetration methods
of weathering are distinguished: a phase of approximate duration 100,000 yr in which most weathering and leaching occurs in the matrix, which becomes increasingly acidified; and a phase from 100,000 to 350,000 yr which is dominated by cation release from stones
, reversal of the acidification trend, and breakdown of stone fabric.
and Oriental hawthorn. Styles transported included grouped rocks, stone lanterns and neatly trimmed shrubs. Such features usually made up a small part of the entire garden of Hawaiian Japanese-Americans, but they were frequent enough to suggest a display
disturbance to the pavement cover, if not too extensive, can also be repaired by this mechanism. The cross-surface flux of stones also represents a powerful smoothing agent, lowering topographic highs and filling topographic depressions. The results presented
