TL;DR: In this article, a detailed geochronological, geochemical, and Sr-Nd isotopic studies have been undertaken for most of these plutons, in an attempt to provide a comprehensive understanding in the age, genesis and geodynamical control of the extensive magmatism.

TL;DR: The Tongshankou granodiorite has geochemical features similar to slab-derived adakites, such as high Sr (740-1,300 ppm) and enrichment in light rare earth elements (REE), low Sc (<10 ppm), Y (<13.3 ppm), and depletion in heavy REE (<1.2 ppm Yb), and resultant high Sr/Y (60-92 and La/Yb (26-75) ratios as discussed by the authors.

TL;DR: In this article, the authors propose a model in which the petrogenesis of the Caico* Complex orthogneisses begins with partial melting of a metasomatically enriched spinel-to garnet-bearing lherzolite (with high-silica adakite melt as the metasomatic agent), generating a basic magma that subsequently evolved at depth through fractional crystallization of olivine, followed by low-pressure intracrustal fractionation.

TL;DR: In this paper, the authors proposed a convergent tectonic model in which hybridisation of the upper mantle occurs through interactions with adakitic or trondhjemitic melts and recycling of earlier crust, and showed that both the subducted oceanic crust and the mantle wedge played major roles in continent formation throughout successive episodes of arc accretion in Palaeo- and Mesoarchean times.

TL;DR: The Rio Maria granite-greenstone terrain (RMGGT) is a well preserved Mesoarchaean domain composed of metavolcanic rocks and several suites of granitoids ranging in age from 2.96 to 2.87 Ga.
