Silurian high-pressure granulites from Central Qiangtang, Tibet: Constraints on early Paleozoic collision along the northeastern margin of Gondwana

“…Belomorian tectonic province; Mints et al, 2010) to Cenozoic (e.g. Himalayas; Liu and Zhong, 1997), are important indicators of plate convergence and collision following the subduction of oceanic or continental crust (O'Brien and Rötzler, 2003;Ernst and Liou, 2008).…”

Geology and metallogenic potential of the northwesternmost Norrbotten Province around Altevatn in Troms, northern Norway

“…Archaean rocks predominate in the northeast, and include tonalitetrondhjemite-granodiorite (TTG) suites, subordinate greenstone belts and paragneisses, yielding ages mainly between 2.9 and 2.7 Ga (Hölta et al, 2008 and references therein). High-grade metamorphic events recorded in these rocks include 2.9-2.7 Ga, eclogite-or granulitefacies metamorphism, as well as younger, c. 1.9 Ga, highgrade metamorphic overprinting Mints et al, 2010;Skublov et al, 2011), related to Fennoscandian reamalgamation.…”
