The concept of I‐ and S‐type granites was introduced in 1974 to account for the observation that, apart from the most felsic rocks, the granites in the Lachlan Fold Belt have properties that generally fall into two distinct groups. This has been interpreted to result from derivation by partial melting of two kinds of source rocks, namely sedimentary and older igneous rocks. The original publication on these two granite types is reprinted and reviewed in the light of 25 years of continuing study…

Post-Archean granitic rocks: contrasting petrogenetic processes and tectonic environments
Abstract Granitic rocks represent a ubiquitous component of upper continental crust but their origin remains highly controversial. This controversy stems from the fact that the granites may result…
Origin of S-, A- and I-Type Granites: Petrogenetic Evidence from Whole Rock Th/U Ratio Variations
The origin and evolution of granites remain a matter of debate and several approaches have been made to distinguish between different granite types. Overall, granite classification schemes based on…
Possible Biosphere-Lithosphere Interactions Preserved in Igneous Zircon and Implications for Hadean Earth.
TLDR
It is observed that zircons found in S-type granitoids formed under more reducing conditions than those formed from I-typegranitoids from the same terrain, consistent with the incorporation of (reduced) organic matter in the former and highlights one possible manner in which life may modify the composition of igneous minerals.
Carboniferous Granitoid Magmatism of Northern Taimyr: Results of Isotopic-Geochemical Study and Geodynamic Interpretation
Data on the petrography, geochemistry, and isotopic geochronology of granites from the northern part of the Taimyr Peninsula are considered. The Early–Middle Carboniferous age of these rocks has been…
Extensive charnockitic-granitic magmatism in the crystalline crust of West Lithuania
A number of plutons of charnockitic and granitic rocks have been revealed in the West Lithuanian Granulite Domain in the course of the recent geological mapping. Th e largest, Kursiai (Curonian),…
Low- and high-temperature granites
ABSTRACT I-type granites can be assigned to low- and high-temperature groups. The distinction between those groups is formally based on the presence or absence of inherited zircon in relatively mafic…
U–Pb zircon geochronology of Silurian–Devonian granites in southeastern Australia: implications for the timing of the Benambran Orogeny and the I–S dichotomy
Despite extensive geochemical study and their importance to granite studies, the geochronology of Silurian to early-Devonian granitic rocks of southeastern Australia is poorly understood. In order to…

Abstract The 365-Ma You Yangs batholith is a mainly I-type monzogranitic body, containing rocks with both clinopyroxene and hornblende, but with a 2–2.5 km-wide rim of S-type rocks. In places, the…
Precambrian Crustal Evolution in the Great Falls Tectonic Zone: Insights from Xenoliths from the Montana Alkali Province
Zircon U-Pb ages, Lu-Hf data, and whole-rock Sm-Nd data from xenoliths in the Eocene Grassrange diatremes of central Montana reveal the presence of Proterozoic-Archean crust at depth in the Great…
