Incipient plutonism in the early Permian resulted in the formation of isotopically evolved, peraluminous granodiorites of the Hillgrove Suite. Following this, mixing between crustal-derived (+ 5–+ 8 εHf units) and depleted mantle-derived magmas (+ 13–+ 18 εHf units), was responsible for the formation of the c. 282 Ma Bundarra Suite.

Evidence for rutile-bearing eclogite in the mantle sources .

rutile-bearing eclogite should also play an important role in the formation of the Ninghai basalts, in addition to mantle peridotite. The terrestrial mantle-likeMg-isotopic compositions of the Ninghai basalts further support their formation by high-degree partial melting of such mixed source. In the plots of Sr-Nd isotopes and Ti/Ti*,

Rutile-Bearing Refractory Eclogites: Missing Link Between .

McDonough suggested that refractory, rutile-bearing eclogite may satisfy the mass balance requirements for Ti, Nb, and Ta in the silicate Earth. Here we show that eclogites, sampled in xenoliths from cratonic kimberlites, do indeed have the requisite trace element compositions to satisfy this mass imbalance.
