The origin of metavolcanic and associated argillaceous rocks at Island Bay, Wellington, New Zealand

New Zealand Journal of Geology and Geophysics, 1985
Abstract The alternating greywacke‐argillite turbidite beds exposed on the eastern side of Island Bay, Wellington, New Zealand, belong to the Torlessia fossil zone of the Torlesse Supergroup. They were deposited in a deep‐water marine environment.

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.

Age and tectonic setting of Mesozoic metavolcanic and metasedimentary rocks, northern White Mountains, California

Geology, 1987
Mesozoic metavolcanic and metasedimentary rocks in the northern White Mountains, eastern California and western Nevada, are separated from lower Paleozoic and Precambrian rocks by Jurassic and Cretaceous plutons. The large stratigraphic hiatus across the plutons is called the Barcroft structural break. Recent mapping and new U/Pb zircon ages of 154 +3/−

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.
