This study combines the microstructural and petrological analysis of garnet its inclusions in quartzite-hosted garnetite from ultrahigh-pressure Lago di Cignana metaophiolite (Western Alps). We present a comprehensive record metamorphism, compaction, state stress during interaction between oceanic metasediments infiltrating fluids along major open-system fluid pathway. The arrangement into laye...

The mid-Proterozoic (ca. 1850–850 Ma) is a peculiar period of Earth history in many respects: ophiolites and passive margins this age are rare, whereas anorthosite A-type granite suites abundant; metamorphic rocks typically record high thermobaric (temperature/pressure) ratios, ultrahigh pressure (UHP) rare; the abundance economic mineral deposits features rare porphyry Cu-Au abundant Ni-Cu Fe-...
