Efectos de la meteorización laterítica pretriásica en dolomías del Silúrico-Devónico de la Cordillera Costero Catalana (NE España)

As result of tectonic uplift during the last stages (Permian) of the Hercynian orogeny, the outcropping rocks of Catalan Coastal Ranges (metamorphic, igneous and sedimentary rocks) were submitted to extensive chemical weathering under warm, humid climatic conditions that produced a weathering profil...
