and metamorphism in a latest Oligocene metamorphic core complex in northwest Turkey.
45 Ga anorthosite-mangerite-charnockitegranite (AMCG) plutonism
in Lithuania: implications for the Mesoproterozoic evolution of the East European Craton.
05Ga syntectonic plutonism
in the Nyong Group, South-Western Cameroon: consequences for the Eburnean-Transamazonian belt of NE Brazil and Central Africa.
Topics include: Plutonism
versus Neptunism, the sanukitoid series, the geochemistry of Archaean plagioclase-rich granites as a marker of source enrichment and depth of melting, chemical structure in granitic magmas, and more.

2003, Re-Os and U-Pb geochronology of the Clear Creek, Dublin Gulch and Mactung deposits, Tombstone Creek, Yukon: absolute timing relationships between plutonism
and mineralization: Canadian Journal of Earth Sciences, v.
Tectonic environments and sources of magmatism have not been studied using modern petrological techniques based on minor element and isotope geochemistry and, thus, the tectonic settings of orogenic volcanism, plutonism
, and sedimentation in Estonia are so far poorly understood.
The book covers subjects such as the age of the earth, catastrophism vs uniformitarianism, evolution vs creationism, plutonism
vs neptunism, continental drift and plate tectonics.
The earliest Carboniferous igneous activity in the Baltic Sea and NE Poland overlaps in time with the volcanism and plutonism
elsewhere in NW Europe.
Anns Leucogranite has yielded a younger, Cambrian age using the Rb-Sr isochron method (Cormier 1980) and may represent a later phase of plutonism
Exposed crustal cross sections provide a direct view of continental crust, and are a major source of insight into variations in lithologic and geochemical composition, structural style, metamorphism, plutonism
, and rheology.
