Quantification of pedogenic particles masked by geogenic magnetic fraction

Quantification of pedogenic particles masked by geogenic magnetic fraction

Abstract Pedogenic magnetic fraction in soils is attributed to fine-grained particles, i.e. superparamagnetic grains. In the case of a strongly magnetic geogenic fraction, pedogenic magnetic contribution is hard to detect. To the best of our knowledge, detailed research into the masking of pedogenic...
