Portuguese term or phrase: capa de alteração
From a geological/hydrological study. This particular sentence is talking about aquifers. I see many hits on "capas de alteração" on the net (wrt aquifers), but I don't know the technical translation for this term.

Nas formações cristalinas a água subterrânea circula preferencialmente pelas capas de alteração mais superficiais, representando estas formações, em muitos casos, a zona de recarga e o depósito superficial do aquífero cristalino mais profundo.

Thanks
