Rock block monitoring of rapid salt weathering in southern Tunisia

Rectangular blocks of York Stone and of concrete placed on a sodium chloride sabkha in southern Tunisia for six years suffered very severe breakdown, thereby indicating the power of salt weathering as a process in sebkha environments.

Spatial distribution of chloride and nitrate within an unsaturated dune sand of a cold-arid desert : Implications for paleoenvironmental records

Spatial distribution of chloride and nitrate within an unsaturated dune sand of a cold-arid desert : Implications for paleoenvironmental records
Based on chloride mass balance approach, the AA. used two tracers (Cl− and NO3−) to study the interstitial water in four profiles of an unsaturated dune sand. The aim was to reconstruct the recharge history and use this to infer the long-term

Trace element geochemistry in the waters of Pulicat Lake, South India

increase with increase of pH, chlorides and sodium in both monsoon and dry seasons. The concentration and the behaviour of the trace elements are controlled by adsorption, supplemented by organic reactions and by precipitation in sulphide-rich environments.

Experimental frost and salt weathering of chalk-II

Experiments are described in which chalk cubes were soaked in solutions of either sodium chloride, sodium sulphate, or magnesium sulphate. After removal of excess liquid, the cubes were subjected to six freeze-thaw cycles with temperatures ranging

Hydrochemical study of groundwater in recharge area, Wadi Fatimah basin, Saudi Arabia

This study deals with the hydrochemical characteristics of groundwater in the upper catchment of Wadi Fatimah basin on the Arabian Shield. The analysis of data indicated strongly that the chloride and sulfate in the groundwater are mainly of marine

The Mexican salt industry 1560-1980. A study in chance.

Mexico has not only developed the widest range of methods for recovering sodium chloride worldwide, it was also the first country to use salt on a large scale for industrial purposes. From about 1560 to the 20th century, Mexico refined its silver

Automorphic saline soils in Israel in Aridic soils and geomorphic processes.

to the gypsic horizon is related to the depth of moisture penetration in wetter years. The profile distribution of the more soluble chloride salts reflects more closely the recent moisture regime.

Observations of three-dimensional salt distribution in building sandstone

of sulphur and chloride, where distributions are not consistent between salt types, dictated by conditions at the 6 surfaces of the blocks. This highlights the dangers of extrapolating the results of salt weathering simulations with regard to salt

Spatial variability of soils developing on basalt flows in the Potrillo volcanic field, southern New Mexico : prelude to a chronosequence study

The spatial variability of swale soils results in part from the significant hydrologic variability of low-lying landscape positions. Depth profiles of chloride concentrations suggest that hydrologic variability systematically correlates

Flow and chemical composition of drainage water from farmland in the Belgian loamy region. Part 2. Patterns of irons leaching with particular reference to nitrate

. They were lower for land under cereals than under sugar-beets. When the available nitrogen for leaching was high, nitrate and chloride were not leached together. At this moment, the NO3 concentration was positively related with the flowrate and the Ca

A morphological approach to understanding preferential flow using image analysis with dye tracers and X-ray computed tomography

This paper describes a multi-scale approach to analyse transport mechanisms using visualisation techniques. Chloride and Brilliant Blue tracers were applied to undisturbed soil cores to examine the physical and morphological properties associated
