Chemical weathering on the glacial foreland of Storbreen, Jotunheimen Mountains, Norway
Mountains of Norway. Its Little Ice Age maximum occurred about 1750 when it deposited a well-defined end moraine. Since then it has retreated leaving a series of recessional moraines. All of these moraines have been dated lichenometrically by Matthews (see Matthews, 1992 for a comprehensive summary). We used this series of dated moraines to investigate the early stages of pedogenesis, the early...
متن کاملQuantifying glacial moraine age, denudation, and soil mixing with cosmogenic nuclide depth profiles
[1] Glacial boulders and soils on moraines are often dated to quantify the timing of glaciations and/or rates of chemical weathering in moraine chronosequences. A common assumption is that moraine crest erosion and soil mixing are unimportant. However, several studies suggest moraine denudation may be substantial. We evaluate the magnitude of moraine denudation and soil mixing in the Pinedale (...
متن کاملRock weathering creates oases of life in a high Arctic desert.
During primary colonization of rock substrates by plants, mineral weathering is strongly accelerated under plant roots, but little is known on how it affects soil ecosystem development before plant establishment. Here we show that rock mineral weathering mediated by chemolithoautotrophic bacteria is associated to plant community formation in sites recently released by permanent glacier ice cove...
متن کاملAn instability theory for the formation of ribbed moraine, drumlins and mega-scale glacial lineations.
We present a theory for the coupled flow of ice, subglacial water and subglacial sediment, which is designed to represent the processes which occur at the bed of an ice sheet. The ice is assumed to flow as a Newtonian viscous fluid, the water can flow between the till and the ice as a thin film, which may thicken to form streams or cavities, and the till is assumed to be transported, either thr...
متن کاملEstimation of zeolite application effect on solute transport parameters at different soils using HYDRUS-1D model
ABSTRACT-Application of models for simulation of solute and pollutants transport in soil can reduce time and costs for remediation process. HYDRUS-1D model was developed to simulate the one–dimensional flow of soil water, heat, solute and viruses in variably saturated–unsaturated porous media. The objective of this investigation is to determine the solute transport parameters in disturbed soil ...
