Despite these challenges, it is clear that the combined study of the plutonic and volcanic record can complement the information available from plutonic rocks alone. Over the years, there has been a controversy regarding the tectonic setting in which TTG-type magmas formed, so that clari- fying ...
The extrusion of these felsic and mafic volcanic rocks was coeval with plutonic equivalents recorded by abundant A-type magmatism (Barros et al., 1997, 2001, 2009; Barbosa, 2004; Gomes, 2006; Sardinha et al., 2006; Feio et al., 2012, 2013; Dall'Agnol et al., 2017; Marangoanha et ...

Gabbros and diorites collected from the Paleocene Tanadaro intrusion are compositionally similar to the associated volcanic rocks and, we consider, represent the plutonic equivalents of high-Al basalt. The geochemistry of Cretaceous turbiditic sedimentary rocks on Sumba indicates close proximity to an ...

The S-type volcanic rocks are not the simple erupted equivalents of the granites, although the extrusive and plutonic units can be related by open-system magmatic evolution. Zircons in the S-type rocks define covariant εHf–δ18O arrays that attest to mixing or assimilation processes between ...
Three suites of late Silurian S-type volcanics are described, two of which can be matched quite closely with plutonic equivalents. A large part of the Paleozoic continental margin volcanic activity in southeast Australia consisted of the magmatic recycling of old metasedimentary crust, probably of ...
The ages, initial 87 Sr/ 86 Sr (I Sr ) and major element compositions of the augen gneisses of Arola and Suomussalmi indicate that these rocks are the plutonic equivalents of the Luoma acid volcanics. The Arola pink leucogranite marks the terminal phase of Archaean magmatic activity (from ...
