Limited fluid-rock interaction at marble-gneiss contacts during Cretaceous granulite-facies metamorphism, Seward Peninsula, Alaska

In a study, stable-isotope profiles indicated that flat-lying marble units acted as impermeable barriers to upward fluid flow in transitional amphibolite-granulite grade rocks of the Kigluaik Mountains in Seward Peninsula AK. Channelized fluid pathways through the marble units developed during uplif...

Zusammenfassung:	In a study, stable-isotope profiles indicated that flat-lying marble units acted as impermeable barriers to upward fluid flow in transitional amphibolite-granulite grade rocks of the Kigluaik Mountains in Seward Peninsula AK. Channelized fluid pathways through the marble units developed during uplift and cooling but were not present during peak metamorphism.
