Farrah and Pickering (1976) attribute polynuclear bridged copper(II) species to be the predominant adsorbed species on kaolinite. Moreover cadmium can form comparatively stable chloride complexes in solution which will not get re-adsorbed once it happened to desorb into the solution due to the prevailing conditions ( Doner, 1978 ).
The adsorption of copper and other heavy metals onto clay minerals is an important process that controls the distribution of trace metals in natural environments. Copper isotopes are a potentially useful tool to track the source of contaminated metals in soils formed in natural systems, but Cu isotope fractionation during adsorption onto clay minerals, the major …

As a result, the formation and destruction of magnetite would lead to changes in magnetic susceptibility, which can be used as a proxy to discern potassic versus phyllic alteration (Clark et al. 1992; Purucker and Clark 2011; Clark 2014).Potassic-altered rocks with high magnetic susceptibility have been reported in many porphyry copper deposits, e.g., at …
