Pathway Weathering in Granitoid Rocks from Central Region of Angola: Geochemical and Mineralogical Data [PDF]
, 2012 The Central Region of Angola is characterized by the abundance of granitoid rocks, whose weathering “in situ” originated the so-called residual soils. The textural, geochemical and mineralogical properties of these soils depend not only on the chemical ...
