TL;DR: Olivine phenocrysts' compositions record differences in the contributions of pyroxenite-derived melts in mid-ocean ridge basalts, which imply involvement of 2 to 20% (up to 28%) of recycled crust in mantle melting.

TL;DR: The K2O^SiO2 diagram, used to divide volcanic arc rocks into rock types (basalts, basaltic andesites, dacites and rhyolites) and volcanic series (tholeiitic, calc-alkaline and shoshonitic), is particularly susceptible to the effects of alteration as discussed by the authors.

TL;DR: The term Anthropocene has been proposed and increasingly employed to denote the current interval of anthropogenic global environmental change as mentioned in this paper, which is considered as a formal epoch in that, since the start of the Industrial Revolution, Earth has endured changes sufficient to leave a global stratigraphic signature distinct from that of the Holocene or of previous Pleistocene interglacial phases, encompassing novel biotic, sedimentary and geochemical change.

TL;DR: In this article, the authors argue that the Iceland plume played a pivotal role in the formation of the North Atlantic Igneous Province because the simultaneous and widespread initiation of activity requires a major thermal event in the mantle.

TL;DR: The Cenomanian-Turonian boundary (90.4 Ma) represents a major period of worldwide environmental disturbance as discussed by the authors, leading to the formation of oceanic black shales and the extinction of 26% of all genera.
