The very low water content of the granulitic unit of Holsnøy, in the Bergen Arcs, Norway, caused its partial metastable preservation throughout Caledonian burial end exhumation, leading to the observed mixture of completely eclogitized and uneclogitized rocks. Large-scale eclogite-facies fracturing enabled fluid penetration into the granulite and subsequent eclogitization, and resulted in a ver...

This paper is an outgrowth of the compilation of metamorphic information for the Canadian Shield in Ontario, and complements the recently compiled Metamorphic Map of the Canadian Shield. The paper contains a summary of the Archean metamorphic history of the Superior Province in Ontario on a subprovince basis, with an emphasis on the limitations of the existing data and the reasoning applied in ...

The article describes the history of studying diamond content tectonic structures territory Belarus. Based on results magnetometric, mineralogical, studies carried out by industrial geologists and scientists over past 50 years, new scientifically substantiated criteria for search explosion pipes have been developed using Clifford’s rule, according to which kimberlite are within Archean cratons,...

We present a comprehensive petrological and geochronological study of single granulite sample from the lithosphere-scale Beraketa shear zone in southern Madagascar to constrain orogenic history Gondwana assembly this region. The studied provides panoply data constraining prograde, retrograde, late metasomatic region via application Ti-in-quartz, Ti-in-zircon, Zr-in-rutile, Al-in-orthopyroxene t...

Lunar highland meteorites contain fragments of metamorphic granulites with a wide range of Mg* (molar Mg/(Mg+Fe)) [1], between that of Mg-suite plutonics and magnesian anorthositic granulites (MAG), and those of ferroan anorthosites (FAN), Figure 1 [2,3]. The intermediate-Mg* granulites have been inferred (explicitly or implicitly) to represent mixtures of FAN and MAG or Mg-suite rocks. To test...

The connection between the North China Craton (NCC) and contiguous cratons is important for the configuration of the Nuna supercontinent. Here we document a new Paleoproterozoic high-pressure (HP) complex dominated by garnet websterite on the northern margin of the NCC. The peak metamorphism of the garnet websterite was after ∼1.90 Ga when it was subducted to eclogite facies at ∼2.4 GPa, then e...
