Neoarchean granitoids occurring within the Central Zone of the Limpopo Complex include the ~2.73-2.64 Ga biotite±amphibole-bearing Alldays granitoid, the ~2.68- 2.62 Ga garnet-bearing Singelele leucogranite, the ~2.65-2.63 Ga Avoca granitoid with pyroxene-bearing and pyroxene-absent variants, the ~2.65-2.62 Ga biotite-bearing Verbaard granitoid and the ~2.61-2.58 Ga Bulai granitoid with

The granitoid gneiss samples are characterized by high Al 2 O 3 contents, moderate to high Sr/Y, (La/Yb) N and Na 2 O/K 2 O ratios, no obvious Eu and Sr anomalies, and depleted Nb, Ta, and Ti values that are similar to those of Archean trondhjemite–tonalite–granodiorite (TTG) suites, indicating that the investigated rocks belonging to TTG‐series rocks. Granitoid rocks of the Puritan Quartz Monzonite and associated biotite gneiss and amphibolite in northwestern Wisconsin compose the southwestern part of the Puritan batholith of Late Archean age. Road cutting north of Pigg's Peak in Swaziland, displaying Eoarchaean (c. 3644 Ma) gneisses and migmatites of the Ancient Gneiss Complex and crosscutting dykes of younger, homogeneous granodiorite The granitoid gneisses from the Daqingshan complex of this study consist of TTG gneisses and MG (monzogranitic and granitic) gneisses. They show similar geochemical characteristics. Gneiss and migmatite samples from the southern part of the Western Gneiss Complex of Norway define a single U–Pb zircon discordia line with lower and upper intercepts at 1633 ± 8 Ma and 969 ± 8 Ma. The upper intercept is interpreted as the magmatic age of the protoliths, showing that the basement rocks were generated during the Gothian orogeny (1750–1500 Ma). The migmatites yield Granitoid rocks ranging in composition from granite to tonalite are the dominant rocks exposed in the south western part of the Puritan batholith.

This belt is composed of several suites of tonalite-granodiorite- Dziggel, Annika; Armstrong, Richard; Stevens, Gary; Nasdala, L. Description. SHRIMP U-Pb zircon and titanite dating have been used to constrain the timing of mid- to lower-crustal metamorphism (∼650-700°C and 8-11 kbar) and syn-kinematic melting in the granitoid gneiss-dominated terrane south of the Barberton greenstone belt, S Granitoid gneiss is a variety of metamorphic gneiss that appears to have bands of black and white minerals such as feldspar and mica.
