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 ...

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 ...
Middle Miocene calc-alkaline volcanism in Central Patagonia (47°S): Petrogenesis and implications for slab dynamics Volcanismo calcoalcalino durante el Mioceno Medio en Patagonia Central (47°S): Petrogénesis e implicaciones en la dinámica de placas
(Servicio Nacional de Geologia y Mineria, 2010)
We present a chronological (K-Ar), petrologic and geochemical study (major and trace elements, Sr- Nd isotopes) of Middle Miocene (ca. 16-14 Ma) calc-alkaline rocks (basalts to andesites) extruded in the present-day back-arc ...
