Critical tests of vertical vs. horizontal tectonic models for the Archaean East Pilbara Granite–Greenstone Terrane, Pilbara Craton, Western Australia
TLDR
In this article, an integrated model of punctuated partial convective overturn of the upper and middle crust in response to dominantly magmatic processes is presented to explain the ca. 750 Myr history of the terrane.About:

A catalytic delamination-driven model for coupled genesis of Archaean crust and sub-continental lithospheric mantle
TL;DR: In this paper, the authors proposed a model for the near-coeval formation of the Archaean continental crust (dominantly tonalite-trondhjemite-granodiorite: TTG), which can be explained by melting the base of basaltic plateaux formed above mantle upwellings (plumes), leaving behind restites containing pyroxene, garnet, and rutile.

Review: secular tectonic evolution of Archean continental crust: interplay between horizontal and vertical processes in the formation of the Pilbara Craton, Australia
TL;DR: The Archean Pilbara Craton contains five geologically distinct terranes (the East Pilbara, Karratha, Sholl, Regal and Kurrana Terranes) all of which are unconformably overlain by the 3.53-3.17-Ga De Grey Superbasin this article.

Geological and trace element evidence for a marine sedimentary environment of deposition and biogenicity of 3.45 Ga stromatolitic carbonates in the Pilbara Craton, and support for a reducing Archaean ocean
TL;DR: The authors used trace element geochemistry from a number of laminated stromatolitic dolomite samples of the c. 3.40 Ga Strelley Pool Chert and Dresser Formation to test the origin of the deposits.

Volcanic degassing, hydrothermal circulation and the flourishing of early life on Earth: A review of the evidence from c. 3490-3240 Ma rocks of the Pilbara Supergroup, Pilbara Craton, Western Australia
TL;DR: In the case of the Warrawoona Group of the Pilbara Craton, the authors of as discussed by the authors show that most bedded chert units originated as epiclastic and evaporative sedimentary rocks that were silicified by repeated pulses of hydrothermal fluids that circulated through the footwall basalts during hiatuses in volcanism.

Uniform-sense normal simple shear of the continental lithosphere
TL;DR: In this article, the authors suggest that the thin crust characteristic of the Basin and Range Province extends eastward beneath the west margin of the Colorado Plateau and the Rocky Mountain regions.

A model for Trondhjemite-Tonalite-Dacite Genesis and crustal growth via slab melting: Archean to modern comparisons
Mark S. Drummond,Marc J. Defant +1 more
TL;DR: In this paper, the authors introduced the importance of subducted oceanic crustal age on arc petrogenesis and demonstrated that Archean TTD crustal generation processes are also present in selected high-Al Phanerozoic TTD terranes.
Journal ArticleDOI
Effect of steeper Archean geothermal gradient on geochemistry of subduction-zone magmas
TL;DR: A comparative study of Archean and post-Archengitic granitic rocks shows significant changes with time as mentioned in this paper, which is a direct consequence of the cooling of Earth, and the high rare-earth element fractionation and the low Yb content of the Archean granitoids indicate the major role of garnet and hornblende, whereas these two minerals do not play a prominent part in the genesis of modern granitic rock.

Structural geology of rocks and regions
TL;DR: In this article, the authors present a detailed analysis of structural geology, including deformation mechanisms and microstructures, and their relationship to structural structures and deformation mechanism and dynamic analysis.
