Italian term or phrase: ammassi isolati da stratificazioni impermeabili
Qui non ho proprio capito cosa intenda, si parla di esami CPT:
"La resistenza alla punta qc e l’attrito laterale locale fs nonché la pressione nei pori “u” vengono riportati nel grafico così come il rapporto percentuale Rf = 100 * fs / qc detto “rapporto di frizione”. La punta e le aste ad essa collegate vengono spinte nel terreno mediante un sistema idraulico e telaio di contrasto montato, in genere, su un autocarro il cui peso fornisce il contrasto necessario all’avanzamento dell’attrezzo. La punta viene inserita alla velocità standard di 2 cm/s. Alla fine dell’infissione di ogni singola asta, di lunghezza di un metro, la prova viene sospesa e si ritira verso l’alto la testa di spinta per poter avvitare un nuovo segmento d’asta e riprendere la prova per il metro successivo. Il diagramma della pressione nei pori “u” può rilevare l’andamento della pressione con la profondità; nei terreni permeabili essa coincide circa con la pressione statica, l’estrapolazione verso l’alto consente di stimare la posizione della falda (o eventuali posizioni di più falde in ammassi isolati da stratificazioni impermeabili)."

masses isolated by impermeable strata
Explanation:
We are talking about the position of water tables here, ground water therefore, which has been isolated in big blobs of ground (soil rather than rock, so just masses, not rock masses, and masses rather than layers) by impermeable strata which is very probably rock. You could take Isabelle's suggestion of isolated masses trapped by, but IMHO you want "masses", which may or may not be veins.

I think this is what you need.

However, as the fluid boundary-layer thickness will be much less than the block .... Minimum exit vapor fraction for an isolated vein in impermeable host rocks.

You could put the word trapped in too. Lots of references.
