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 ...

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 ...
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...
The OJB term is, however, very inappropriate since Jönköping is located far to the west and Oskarshamn far to the east of the presently known distribution of this rock complex. For that reason, the original name, Vetlanda-Oskarshamn belt, will be used in this paper, and it is ...
