Continents, especially their Archean cores, are underlain by thick thermal boundary layers
that have been largely isolated from the convecting mantle over billion-year timescales, far …

Unlike in the ocean basins where the shallow mantle eventually contributes to the
destruction of the overlying crust, the shallow mantle beneath continents serves as a stiff …

Since the early 1950s, the number of international measurement standards for anchoring
stable isotope delta scales has mushroomed from 3 to more than 30, expanding to more …

Zircon megacrysts represent a late stage in the crystallisation of the magmas that produced
the low-Cr megacryst suite (Ol+ Opx+ Cpx+ Gnt+ Ilm+ Phl+ Zir) found in many kimberlites …

We present an estimate for the composition of the depleted mantle (DM), the source for mid‐
ocean ridge basalts (MORBs). A combination of approaches is required to estimate the …

铼-锇同位素定年已经成为矿床学乃至于地质学领域最重要的定年技术之一.
文章简略地回顾了铼-锇同位素体系技术方法的发展过程; 介绍了准确测定187Re …

Basalts and mantle peridotites of mid-ocean ridges are thought to sample Earth's upper
mantle. Osmium isotopes of abyssal peridotites uniquely preserve melt extraction events …

The Re-Os isotopic systematics of spinel-and garnet-bearing mantle xenoliths from North
and Central America, Europe, southern Africa, Asia, and the Pacific region were determined …

Archaean–Proterozoic crust, atop a thick (180 km), cold (40 mW/m2), melt-depleted mantle
keel, characterised the North China Craton (NCC) at the end of the Precambrian. Differing …

Recycled ancient oceanic crust with variable amounts of aging, or inclusion of sediments of
differing types and origins has often been invoked as a source for present‐day ocean island …
