Petrology and Sr-Nd characteristics of the Nova Lacerda dike swarm, SW Amazonian Craton: new insights regarding its subcontinental mantle source and Mesoproterozoic geodynamics
(TAYLOR & FRANCIS INCPHILADELPHIA, 2012)
The NNW-trending Nova Lacerda tholeiitic dike swarm in Mato Grosso State, Central Brazil, intrudes the Nova Lacerda granite (1.46 Ga) and the Jauru granite-greenstone terrain (ca. 1.79-1.77 Ga). The swarm comprises diabases ...
Sr and Nd isotope variations along the Pleistocene San Pedro - linzor volcanic chain, N. Chile: tracking the influence of the upper crustal altiplano puna magma body
(Elsevier, 2017)
Subduction-related magmas that erupted in the Central Andes during the past 10 Ma are strongly affected by crustal assimilation as revealed by an increase in Sr-87/Sr-86 isotope ratios with time that in turn are correlated ...

Sr-Nd-Pb isotopic constraints on the nature of the mantle sources involved in the genesis of the high-Ti tholeiites from northern Parana Continental Flood Basalts (Brazil)
(Elsevier B.V., 2013-10-01)
There has been little research on geochemistry and isotopic compositions in tholeiites of the Northern region from the Parana Continental Flood Basalts (PCFB), one of the largest continental provinces of the world. in order ...
Halogens, trace element concentrations, and Sr-Nd isotopes in apatite from iron oxide-apatite (IOA) deposits in the Chilean iron belt: Evidence for magmatic and hydrothermal stages of mineralization
(Elsevier Ltd, 2019)
© 2018 Elsevier LtdThe ratio of the halogens F and Cl in apatite is highly sensitive to changes in the composition of an evolving silicate melt or aqueous fluid. For this reason apatite chemistry is widely used as a monitor ...
