Nature, affinities and significance of metavolcanic rocks in the Outokumpu assemblage, eastern Finland [PDF]
Bulletin of the Geological Society of Finland, 1984 The rock association of serpentinite‒chrome-silicate skarn‒dolomite-quartz rock‒black schist in the Outokumpu region, in which polymetallic sulphide ore deposits occur, has been compared to an ophiolite.

Gold mobilization during metamorphic devolatilization of Archean and Paleoproterozoic metavolcanic rocks [PDF]
Geology, 2020 Volcanic rocks in Archean and Paleoproterozoic greenstone belts are abundant and have been suggested as potential Au source for orogenic Au deposits. The behavior of Au during metamorphism of these rocks is however, poorly known.

Palaeoproterozoic mafic and intermediate metavolcanic rocks in the Turku area, SW Finland [PDF]
Bulletin of the Geological Society of Finland, 2007 Twenty two samples were analysed from mafic and intermediate volcanic rocks from the Turku area along ~60 km long north-south geotraverse. Geographically and lithologically the samples were divided into the Pargas, Turku and Vahto groups.

The petrology of the metavolcanic rocks of the Rusty Lake area, Manitoba
, 1972 A study of the mineralogical and chemical properties of the metavolcanic rocks of the Rusty Lake greenstone belt was accomplished by means of sampling on a 1000 foot grid.

Geochemical evolution of Dalradian metavolcanic rocks : implications for the break-up of the Rodinia supercontinent [PDF]
Journal of the Geological Society, 2011 Neoproterozoic basaltic magmatism in the Dalradian Supergroup of Scotland and Ireland was associated with the break-up of the Rodinia supercontinent. Magmas were erupted in rift-related basins along a strike length of at least 700 km and during a time ...

Petrology of Metavolcanic Rocks in the Bishop Corners – Donaldson Area, Grenville Province, Ontario
Canadian Journal of Earth Sciences, 1973 A calc-alkalic suite, with an apparent thickness of 7 km, varies from alkali basalt and tholeiite composition in the lowest part exposed, through andesite flows and pyroclastic rocks, to rhyodacite pyroclastics at the top.

Hydrocarbons in the Säviä volcanic schist zone, central Finland [PDF]
Bulletin of the Geological Society of Finland, 1987 Light hydrocarbon gases have been analysed from 21 samples of hydrothermally unaltered and 11 samples of hydrothermally altered metavolcanic rocks from the Säviä volcanic schist zone in the southwestern part of the Proterozoic Vihanti— Pyhäsalmi ...

Geology and Lithogeochemistry of the Supracrustal Sequence and Interlayered Metabasites of NE Santos Dumont Region (MG) [PDF]
Anuário do Instituto de Geociências, 2017 The region near Santos Dumont town consists of a sequence of interlayered metabasic rocks and supracrustal gneisses. Two lithological units were individualized based on geological-structural mapping (1:50,000), petrography and lithogeochemistry: a ...

Strain analysis in the Orijärvi triangle, southwestern Finland; in perspective of tectonic models [PDF]
Bulletin of the Geological Society of Finland, 1999 Finite strain analyses were performed in metavolcanic rocks (agglomerates and pillowed metabasalts) from the Orijärvi area, southwestern Finland. In this area, tight folding (F1) of layered metasedimentary rocks and development of a penetrative axial ...
