Geochemistry and assemblage accretion of metavolcanic rocks in the Beardmore–Geraldton greenstone belt, Superior Province

Canadian Journal of Earth Sciences, 1996
The Beardmore–Geraldton greenstone belt lies between the Wabigoon volcanic arc (Onaman–Tashota terrane) and the Quetico metasedimentary subprovince and thus has an important bearing on the accretionary model that has been proposed for the amalgamation of these terranes.

Geochemistry and tectonic interpretation of some metavolcanic rock units of the western North Cascades, Washington

Geological Society of America Bulletin, 1989
Metavolcanic rocks of the western North Cascades of Washington, including the Chilliwack Group (CG), the Elbow Lake Formation (ELFm), and the Yellow Aster Complex (YAC), have been analyzed for clinopyroxene composition and whole-rock major, trace, and rare-earth elements (REE9s) to determine their original chemistry and tectonic setting.

Geochemistry and Petrology of the Kösedağ metavolcanic rocks, Sakarya Composite Terrane, Northern Turkey

, 2015
Central Pontides in Northern Turkey is a key area, comprising variably metamorphosed and deformed low-grade metavolcanic rocks. In this study we report the geochemical characteristics of the Kösedağ metavolcanics (KMV), and infer their tectonomagmatic ...

Nature of the Angular Unconformity between the Paleozoic Metasedimentary Rocks and the Mesozoic Metavolcanic Rocks in the Eastern Sierra Nevada, California

Geological Society of America Bulletin, 1974
Two major wall-rock sequences, the Paleozoic metasedimentary rocks and the Mesozoic metavolcanic rocks, in the eastern Sierra Nevada, California, are separated by an angular unconformity rather than by a fault as has been proposed by other investigators.
