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.

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.

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.

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).

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).

The new field, mineralogical and geochemical data classify the Jaisamand granitoids into sanukitoids, TTGs, and transitional TTGs, which are most likely coeval in nature.

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).

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 …

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.

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, …
