Session: Debating the Connections Between the Plutonic and Volcanic Rock RecordCordilleran Section Annual Meeting & Pacific
Plutonic rocks of intermediate composition on Gran Canaria: The missing link of the bimodal volcanic rock suite. Contributions to Mineralogy and Petrology 141, 430-445.Freundt-Malecha B, Schmincke H-U, Freundt A (2001) Plutonic rocks of intermediate composition on Gran Canaria: the missing link ...
A comparison between Palaeoarchaean volcanic and plutonic rocks of the eastern Kaapvaal craton allows linking the volcanic and plutonic records. Given the distinctive compositional differences between major intrusive rock types (TTG and GMS series), volcanic rocks can be likened to either one or the ...

TiO2 (d) SiO2 vs. K2O for felsic volcanics of the Siang window, Eastern Himalaya. A.K. Singh, R.K. Bikramaditya Singh / Geoscience Frontiers 3(5) (2012) 613e634 629 at least were derived by partial melting of a similar source composition to that of the mafic volcanic rock (PRO117...
In any case, the restricted compositional range observed for an element scarcely mobile during weathering processes such as TiO2, and the lack of clear relationships between LOI and major oxides (with the exception of CaO) suggest that the bulk rock major element composition (recalculated on ...
This study presents whole-rock major and trace element analyses of volcanic rocks and sills of the BNC to establish their composition and geological setting, and two new U–Pb zircon ages from a rhyolite lava and a rhyolite sill to determine the age of the BNC. In addition, 40Ar/39Ar step...
This work reviews possible signatures and potential detectability of present-day volcanically emitted material in the atmosphere of Venus. We first discuss
