Web1 de jan. de 2016 · Clay minerals form in a range of conditions (pH, temperature, pressure), and clay-rich sediments result from a range of different formation mechanisms, from solid-state alteration to dissolution and neoformation, to detrital inheritance (Singer, 1980 ). WebHence, halloysite-abundant clay minerals of high adsorption capacity in deep regolith could efficiently retain the REEs released from weathering of the parent granite. Reduction in adsorption capacity during the clay transformation in shallow depth partially leads to REE desorption, and the released REEs would be subsequently transported to and adsorbed …
