Contrasting magmatic signatures in the Rairakhol and Koraput alkaline complexes, Eastern Ghats belt, India
(INDIAN ACAD SCIENCES, 2010)
The relation between alkaline magmatism and tectonism has been a contentious issue, particularly for the Precambrian continental regions. Alkaline complexes at the southwestern margin of Eastern Ghats belt, India, have ...
Magmatic and tectonic fabrics in the Upper Jurassic La Hoya Pluton, North Patagonian Batholith (∼43ºS) as a record of the early stages of the Andean deformation
(Elsevier B. V., 2020-08)
The magmatic record of the North Patagonian Batholith starts in Middle Jurassic times and rapidly grew in Early Cretaceous times, where it experienced its main building phase. Slightly after, in the Late Cretaceous, the ...
Fast sediment underplating and essentially coeval juvenile magmatism in the Ordovician margin of Gondwana, Western Sierras Pampeanas, Argentina
(Elsevier Science, 2012-09)
Metasedimentary high-pressure upper amphibolite facies gneisses (1.2 ± 0.1. GPa and 780 ± 45 °C) at Las Chacras, Sierra de Valle Fértil, are tectonically juxtaposed to the westernmost parts (outboard) of the Famatinian ...
Metamorphic evolution and P-T path of gneisses from Goias Magmatic Arc in southwestern Goias State
(Soc Brasileira Geologia, 2013-06-01)
In the southwestern Goias State, the rocks of the Goias Magmatic Arc present mineral assemblages typical of the amphibolite facies. Thermobarometric calculations show that P and T conditions for associations involving ...
Geoquímica de gnaisses do arco magmático de goiás na região sul do estado de goiás
(2007-04-01)
Granitic to trondhjemitic gneisses from the Pontalina region in the southern part of Goiás State, Central Brazil, have calcic to calc-alkaline, metaluminous to peraluminous compositions. They have low concentrations of ...

Temporal histories of Cordilleran continental arcs: Testing models for magmatic episodicity
(Mineralogical Society of America, 2016-10)
Magmatic activity in continental arcs is known to vary in a non-steady statemanner, the mechanisms for which are a matter of ongoing discussion. Ofparticular importance is the question to what extent episodic magmatism ...
Flexural uplift and magmatic underplating anomaly on the Argentine continental margin: profile at 43.5°S
(Springer, 2021-05)
Magmatic underplating can be defined as the addition of mafic magma to the lower crust and uppermost mantle around the Moho. This phenomenon plays an important role in continental margins and other compressional and ...
