Tectonic or subduction erosion refers to the removal of upper-plate material from the forearc
at convergent margins. Subduction erosion has been suggested to represent a major …

Oxygen is the most abundant element in the Earth's crust, mantle, and fluids and therefore its
isotopic composition provides robust constraints on magma genesis. Application of oxygen …

The nine editions of Stable Isotope Geochemistry have appeared over a time span of nearly
50 years. The first edition (1973) appeared as a slim book of 135 pages. Due to the rapid …

Abstract Analysis of δ 18 O in igneous zircons of known age traces the evolution of
intracrustal recycling and crust-mantle interaction through time. This record is especially …

The strong resilience of the mineral zircon and its ability to host a wealth of isotopic
information make it the best deep-time archive of Earth's continental crust. Zircon is found in …

Silicic magmas play an important role in the formation of continental crust and are
responsible for some of the most hazardous volcanic eruptions on the planet. Low-δ 18 O …

The basalts of the 2021 Fagradalsfjall eruption were the first erupted on the Reykjanes
Peninsula in 781 years and offer a unique opportunity to determine the composition of the …

We measured oxygen isotope compositions of 34 adakites, high-Mg andesites, and lavas
suspected to contain abundant slab and sediment melts from the Western and Central …

Massif-type anorthosites, enormous and enigmatic plagioclase-rich cumulate intrusions
emplaced into Earth's crust, formed in large numbers only between 1 and 2 billion years …

Abstract The North China Craton (NCC) has been considered to be part of the
supercontinent Columbia. The nature of the NCC western boundary, however, remains …
