... the Gridino eclogites originated due to an eclogite-facies metamorphic overprint on Mesoarchean mafic dikes. These dikes are widespread over the Gridino area and are referred by all other researchers to a Paleoproterozoic lherzolite-gabbro-norite complex. However, Dokukina and her coauthors ( Dokukina...

... settings in which early TTG crust has been produced are largely uncertain. The primary melt glassy inclusions with a glass phase in cores of prismatic zircon crystals from TTG gneisses provide evidence for the volcanic origin of gneiss protolith. Suggested genetic modeling of TTG-type complexes assumes...

... serpentinites have no equivalents in the other units of the Maksyutov eclogite-glaucophane schist complex and, thus, can be regarded as a separate “mafic-ultramafic” unit. Based on their mineral and chemical composition, the garnet-clinopyroxene and lawsonite-bearing rocks can be interpreted as HP associations...
