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

, 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.

Geochemistry of basalts in unravelling the mantle processes and crustal evolution: Insights from the greenstone belts of western Dharwar Craton

Geosystems and Geoenvironment, 2022
Basalts are an integral part of all the greenstone belts of Dharwar Craton which played a vital role in the thermo-tectonic evolution and mantle processes during the Archean time.

Theoretical petrology [PDF]

, 1979
The central issues in petrology have remained remarkably unchanged in the last 50 years. In igneous petrology, the focus is on understanding the nature and cause of diversity in igneous rocks: on identifying primary magma types and constraints on the ...

The lithospheric mantle and lower crust-mantle relationships under Scotland: a xenolithic perspective [PDF]

, 2011
In the British Isles the majority of volcanic rocks containing upper mantle and lower crustal xenoliths occur in Scotland. Most of the occurrences are of Carboniferous–Permian age.

Early Cenozoic denudation of central west Britain in response to transient and permanent uplift above a mantle plume [PDF]

, 2018
Upwelling mantle plumes beneath continental crust are predicted to produce difficult to quantify, modest uplift and denudation. The contribution of permanent and transient components to the uplift is also difficult to distinguish.
