The Shebandowan group: "Timiskaming-like" Archean rocks in northwestern Ontario
, 1987 This group of Archean volcanic and metasedimentary rocks is generally considered to be younger than the Keewatin metavolcanic rocks. The metasedimentary rocks are disposed in tight to isoclinal folds with strong plunge variations that are mainly due to ...

Progress in the Application of Oxygen Isotopes in the Study of Petrogenesis
Yankuang ceshi, 2013 Since different types of rocks on the earth have different oxygen isotope compositions, they can be used to discuss the origins of various rocks and it has become a powerful tool for studying petrology.

Geology and Petrology of the Kösedağ Metavolcanic Rocks to the south of Tosya
, 2015 The Kösedağ Metavolcanics crops out in the southern Central Pontides as a NE-SW trending belt to the south of Tosya. This unit is characterized by a low-grade metavolcanic assemblage interbedded with metasedimentary lithologies. While these metavolcanics
