Weathering is the fundamental precondition for erosion and soil formation which sculpture Earth´s surface. It is a complex interplay of minerals, rock fabric, tectonical fractures, climate, and organic activity. To explore the dependences between these factors two weathering profiles on magmatic bedrock were compared using six-meter-deep soil pits and drill cores in both a humid and a Mediterranean climate regime of Chile. Detailed mineralogical and geochemical investigations of soil and saprolite were combined with spatially...
