Sanukitoid - Wikipedia
Sanukitoids are a variety of high-Mg granitoid found in convergent margin settings. The term "sanukitoid" was originally used to define a variety of Archean plutonic rock, but now also includes younger rocks with similar geochemical characteristics.
Sanukitoid - SpringerLink
Sanukitoids, also called high-magnesium granodiorites, were first described by Shirey and Hanson (1984). They consist in a complete magmatic series, from diorite to granite; the most common facies consisting in monzodiorites and monzogranites.
Discrimination and origin of the sanukitoid series: Geochemical ...
Mar 1, 2010 · We also propose new ways to discriminate between sanukitoids and TTGs, propose a wider definition for sanukitoids, and discuss the source of sanukitoid magmas and possible tectonomagmatic processes that have formed them.
Geochemistry and petrogenesis of sanukitoids and high-K …
May 1, 2019 · Sanukitoids (s.l.) exhibit geochemical features ranging from alkali to calcic, and include magnesian and mostly metaluminous features as well (Fig. 6 a–c). According to the SiO 2 vs. K 2 O diagram, sanukitoids (s.l.) were classified as medium- to high-K (Fig. 6 d).
Archean TTGs and sanukitoids from the Jiaobei terrain, North …
Aug 1, 2016 · We have identified the late Archean sanukitoids from the Jiaobei terrain where the ∼2.9 Ga, ∼2.7 Ga and ∼2.5 Ga TTGs are well exposed (Jahn et al., 2008, Liu et al., 2013).
Petrogenesis of the Jaisamand sanukitoids and associated TTGs ...
The new field, mineralogical and geochemical data classify the Jaisamand granitoids into sanukitoids, TTGs, and transitional TTGs, which are most likely coeval in nature.
Phanerozoic sanukitoids from Caledonian Scotland: Implications …
Dec 1, 2012 · Sanukitoids represent a volumetrically minor but important series of Neoarchean granitoids enriched in large-ion lithophile elements (e.g., Ba, Sr, and light rare earth elements), and with relatively high compatible elements (e.g., Mg, Ni, and Cr).
The sanukitoid series: magmatism at the Archaean–Proterozoic …
Mar 1, 2009 · A specific type of granitoid, referred to as sanukitoid (Shirey & Hanson 1984), was emplaced mainly across the Archaean–Proterozoic transition. The major and trace element composition of sanukitoids is intermediate between typical …
Evolution of Archean Sanukitoids from the Otto Stock by Magma …
May 27, 2021 · Here, extraordinary textural relations unequivocally show that at the Late Archean Otto stock, Abitibi, Canada, sanukitoids resulted from the assimilation of clinopyroxenite by monzonitic magmas and coeval magmatic–hydrothermal Na–K metasomatism.
Pervasive Neoarchean melting of subducted sediments generating ...
Jan 8, 2024 · In this work, we identified two types of rock units (i.e., sanukitoids and associated adakitic suites, exposed in the Eastern Hebei Complex of the North China Craton) and illustrated their petrogenesis and tectonic context through field, …
