Comment on: 'Genesis of subtropical soils with stony horizons in NE Argentina: Autochthony and polygenesis'. H. Morras, L Moretti, G. Piccolo, W. Zech.Quaternary International (2009), vol. 196 (1-2): 137-159

摘要

We feel it necessary to comment the paper of Morras et al. (2009) in this journal. The authors presented there a re-interpretation about the origin of the "red materials-soils" outcropping in the Province of Misiones, northeastern Argentina. Particularly, they discussed the "tropical loess" theory (Iriondo, 1996; Iriondo and Krohling, 1997, 2007, 2008; Iriondo et al., 1997) focusing their research on the premise that all the materials covering the landscape of Misiones are a product of the weathering of the K-basalt and subsequent pedogenesis, mainly using pedological criteria.
