On the Tertiary and Older Peridotites of Scotland [PDF]

open access: greenQuarterly Journal of the Geological Society of London, 1885
Those rocks which contain an excessive proportion of the bases, especially magnesia and ferrous oxide, and are therefore composed largely of unisilicates, may be conveniently classed as ultra-basic rocks. Such rocks constitute a small but highly interesting group, which is characterized as follows:—They have a very ...

Platinum Group Element Traces of CAMP Volcanism Associated With Low‐Latitude Environmental and Biological Disruptions

open access: yesGeophysical Monograph Series, Page 263-304., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Oxygen-isotope and trace element constraints on the origins of silica-rich melts in the subarc mantle [PDF]

open access: yes, 2007
Peridotitic xenoliths in basaltic andesites from Batan island in the Luzon arc contain silica-rich (broadly dacitic) hydrous melt inclusions that were likely trapped when these rocks were within the upper mantle wedge underlying the arc.
