Viene segnalata la scoperta di scisti a glaucofane in due località nei pressi del passo Shangla, fra la media valle dell’Indo e la valle dello Swat, nel Pakistan Settentrionale. Tale litotipo metamorfico affiora in vicinanza di una lunga linea di faglia che mette a contatto formazioni cretaceo-eoceniche con formazioni paleozoiche o più antiche. La presenza della facies degli scisti blu (scisti a glaucofane) presso la faglia di Patan ed altri elementi, inducono a ipotizzare tale dislocazione come la traccia di un fenomeno di subduzione verificatosi nel Terziario. La faglia di Patan rappresenterebbe la prosecuzione occidentale della sutura dell'alto Indo interpretato da Gansser quale traccia della subduzione del continente indiano sotto il continente eurasiatico.
