Global chemical weathering of surficial rocks estimated from river dissolved loads

Tipo de material: TextoTextoSeries ; American Journal of Science, 287(5), p.401-428, 1987Trabajos contenidos:
  • Meybeck, Michel
Tema(s): Recursos en línea: Resumen: This article starts from the representative water analyses for major rock types commonly found on the continents. A theoretical world average is then set up on the basis of global outcrop proportions and compared to the observed composition. After discussion, this theoretical average is apportioned into the individual contributions from various minerals and rocks. As the water analyses are mostly derived from a previous study of unpolluted monolithologic French watersheds, this approach is called the Temperature Stream Model.
