Rapakivi Granites of the Kodar Complex (Aldan Shield): Age, Sources, and Tectonic Setting

Early-paleozoic rapakivi-textured granite from the North Qinling (Central China): implications for crust–mantle interactions in a post-collisional setting

“…Typical rapakivi granites, such as the Finnish pluton (Sederholm 1891), Korosten pluton, Salmi pluton (Rämö and Haapala 1995), Miyun rapakivi granite (Yang et al 2005), and Kodar Complex (Larin et al 2021) as well as orogenic rapakivi-textured granites such as the Jangart Complex (Konopelko et al 2007;Solomovich and Trifonov 2014), Itu batholith (Pereira et al 2023), Deer Isle pluton (Lux et al 2007;O'Brien et al 2019), Shahewan pluton Zhou et al 2008), and Tataleng pluton (Lu et al 2007a;Hu et al 2008), have a common rapakivi texture characterized by ovoid alkali feldspar porphyry mantled by oligoclase. Despite their remarkable petrological similarity, 1979).…”

“…The main point of contention is whether they were formed during a transitional stage from compression to extension, marking the end of the main orogenic collision and the beginning of intracontinental orogeny (Lu et al 2003;Wang et al 2003Wang et al , 2005Gong et al 2009;Larin 2009;Solomovich and Trifonov 2014;Sun 2017). Studies on rapakivi-textured feldspars have provided important records of plutonic processes (Sederholm 1891;Nekvasil 1991 andHaapala 1995;Haapala et al 2005;Larin et al 2021); however, the crystallization process of these feldspars is still controversially discussed (Hibbard 1981;Nekvasil 1991;Bussy 1990;Dempster et al 1994;O'Brien et al 2019;Alves et al 2021).…”

interest as it provides information about tectonic and crustal evolution (Larin et al 2021; Prasanth et al 2023). Most typical Proterozoic rapakivi granites are found in cratons, with an A-type affinity that is commonly associated with continental rifts (
