Rapakivi granites in the geological history of the earth. Part 1, magmatic associations with rapakivi granites: Age, geochemistry, and tectonic setting

The Río de la Plata Craton: a review of units, boundaries, ages and isotopic signature

“…A SHRIMP zircon U-Pb age of 2,056 ± 6 Ma, reported by Santos et al (2003), is the best estimation of the crystallization age of this granite. This confirms that the Soca Granite should not be considered an example of the typical anorogenic rapakivi association, but an A2-type rapakivi granite of the rapakivi granite-shoshonite rock series, formed after continent collision or arc magmatism (Eby 1992;Larin 2009). In summary, this late-to postorogenic association of granite and gabbro magmatism occurred at 2,080-2,050 Ma and includes medium-to high-K 2 O calc-alkaline, alkaline and rapakivi intrusions.…”

Proterozoic rapakivi granites from the North Qaidam orogen, NW China: Implications for basement attribution

“…Yang et al, 2005). Futhermore, their ages are also consistent with the Mazur (1750 Ma) and Korosten (1790 to 1760 Ma) rapakivi granite plutons in the southeastern East European craton (e.g., Larin, 2009). These data can confirm that the Proterozoic rapakivi granites in the North Qaidam orogen are part of the Proterozoic rapakivi granite province in the northern hemisphere.…”

“…These rapakivi granites are considered as members of the Proterozoic rapakivi granite plutonic association of the northern hemisphere Yu et al, 1996;Larin, 2009). Proterozoic rapakivi granites in the northern hemisphere cratons predominately range in age from 1790 to 1500 Ma (Anderson, 1983;Bettencourt et al, 1999;Dall'Agnol et al, 1999;Larin, 2009). They mainly occur in the East European and North American cratons (e.g., Haapala, 1995, 1996;Elliott, 2001;Sharkov, 2010).…”

“…They mainly occur in the East European and North American cratons (e.g., Haapala, 1995, 1996;Elliott, 2001;Sharkov, 2010). Rapakivi granites with ages of 1790 to 1700 Ma mainly occur in the Siberian and East European cratons Yu et al, 1996;Larin, 2009).…”

“…Typical rapakivi granites are commonly Proterozoic in age and occur in Precambrian cratons, particularly in the northern hemisphere Haapala, 1995, 1996;Haapala and Rämö, 1999;Larin, 2009). They constitute a huge rapakivi granite belt extending from the Siberian and North China cratons to Russia and the Baltic Sea platforms, then through southern Greenland and occupying large areas of the North American continent .…”
