The temporal evolution of sanukitoids in the Karelian Craton, Baltic Shield: an ion microprobe U–Th–Pb isotopic study of zircons

Whole-rock geochemistry of some tonalite and high Mg/Fe gabbro, diorite, and granodiorite plutons (sanukitoid suites) in the Kuhmo district, eastern Finland

“…This phenomenon appears to be regional rather than local as it has been recently demonstrated that the period between 2.74 Ga and 2.70 Ga has been a significant period of sanukitoid magmatism over a large part of the Karelia craton (e.g., Samsonov et al, 2004;Bibikova et al, 2005;Halla, 2005).…”

Mesoarchean sanukitoid rocks of the Rio Maria Granite-Greenstone Terrane, Amazonian craton, Brazil

“…Archean sanukitoid suites have been described over the last 20 years in the Canadian Shield (Shirey and Hanson, 1984;Stern and Hanson, 1991;Stevenson et al, 1999), Pilbara craton (Smithies and Champion, 2000), Karelian craton of the Fennoscandian Shield (Chekulaev, 1999;Lobach-Zhuchenko et al, 2000a,b, 2005 Kovalenko et al, 2005;Bibikova et al, 2005), Zimbabwe craton (Bagai et al, 2002;Kampunzu et al, 2003), Dharwar craton (Moyen et al,2001(Moyen et al, , 2003 and Amazonian craton (Althoff et al, 2000;Souza et al, 2001;Leite et al, 2004;Oliveira et al, 2006a,b;Dall'Agnol et al, 2006). The term sanukitoid suite (or high-Mg diorite suite), first introduced by Shirey and Hanson (1984) for Late Archean felsic intrusive and volcanic rocks from the Superior Province geochemically distinct of the TTG suites, refers to a series of associated high-magnesium rocks (diorites through granodiorites) that have similar geochemical characteristics.…”

Age and petrology of the Kaapinsalmi sanukitoid intrusion in Suomussalmi, eastern Finland

“…In the Karelian craton, sanukitoids are younger than the surrounding TTG, implying that sanukitoids are not directly linked to the subduction processes that might have produced TTGs (Bibikova et al, 2005). The sanukitoid intrusions of the Russian part of the Karelian craton are divided into Eastern and Western sanukitoid zones (�obach-Zhuchenko et al, 2005;Bibikova et al, 2005).…”

“…The sanukitoid intrusions of the Russian part of the Karelian craton are divided into Eastern and Western sanukitoid zones (�obach-Zhuchenko et al, 2005;Bibikova et al, 2005). The sanukitoid intrusions in the Eastern sanukitoid zone were formed 2.730 -2.745 Ga ago.…”

“…Sanukitoid intrusions in the Russian part of the Karelian craton are divided into Eastern and Western sanukitoid zones, which differ in composition and age (�obach-Zhuchenko et al, 2005;Bibikova et al, 2005). Seven sanukitoid intrusions located in Finland have been described: Kuittila (O'Brien et al, 1993), Nilsiä, Koitere (Halla, 2005), Arola, �oso, Siikalahti Käpyaho 2006) and the recently recognised Kaapinsalmi sanukitoid intrusion (Heilimo, 2006a;2006b) (Fig.…”
