P. A1 Osácar, María Cinta A1 López Aguayo, F. AB The Cameros Basin ( N W o f the Iberian Range) is m a in ly composed o f very homogeneous silicic d e tr ita l m aterials in Weald facies. The occurrence o f c h lo rito id , cookeite, p y rite an d muscovite/p aragonite is related to a cretacic very low grade metamorphism. The geochemical analysis of this materials displays differences linked to lithologic features; comparison between metamorphic and no metamorphic materials shows no main differences in the chemical contents, but in the relationships between elements PB Sociedad Geológica de España YR 1996 FD 1996 LK http://hdl.handle.net/10272/12260 UL http://hdl.handle.net/10272/12260 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 1 jun 2026
