Gold mobilization during metamorphic devolatilization of Archean and Paleoproterozoic metavolcanic rocks [PDF]
Geology, 2020 Abstract Volcanic rocks in Archean and Paleoproterozoic greenstone belts are abundant and have been suggested as a 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 [PDF]
, 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. In total, this greenstone belt is exposed over more than 250 square miles.
