Volcanism and tectonic setting

1988
The relationship between volcanism and tectonic setting is a diverse topic. One approach to this subject in recent years has been from a geochemical point of view, the approach being to correlate particular geochemical properties or trends in modern volcanics with their specific tectonic setting, and to use the patterns derived from modern successions ...

Distribution and Tectonic Setting of Kimberlites

Minerals and Rocks, 1980
The general world-wide distribution of kimberlites is shown in Fig. 1 and in greater detail for the main kimberlite provinces in Figs. 2–6. From the aspect of the tectonic setting of kimberlite, Dawson (1970) established that, in the case of the kimberlites of Africa, most kimberlites are confined to the ancient cratons (or areas underlain by the ...

OXYGEN FUGACITY ACROSS TECTONIC SETTINGS

Goldschmidt2022 abstracts, 2020
Experiment and observation have established the centrality of oxygen fugacity (fO2) to determining the course of igneous differentiation, and so the development and application of oxybarometers have proliferated for more than half a century. The compositions of mineral, melt, and vapor phases determine the fO2 that rocks record, and the activity models

Magmatism and tectonic settings

Journal of Geophysical Research, 1972
Mutual relationships of mobile lithospheric plates define two distinct tectonic environments each characterized by diagnostic magmatism. A compressional environment occurs at loci of plate convergence; quartz- and hypersthene-normative intermediate, acid and basic members of the calc-alkaline orogenic suite are emplaced above a dipping seismic zone.
