Description :
Mineralogical and structural features control the weathering processes and landform development of 2 different crystalline stocks in the Iberian Massif : the Santa Elena and Linares stocks. Mineralogical and geochemical evidence indicate the Santa Elena materials are more intensely weathered. High fracturation and high Ca-richer plagioclase contents are key factors producing the pervasive Santa Elena stock weathering. Fluvial erosion removed the alteration products in incised tectonically controlled streams resulting in boulder accumulation.
