Despite its low abundance in most rocks, zircon is extraordinarily useful in interpreting
crustal histories. The importance of U-Th-Pb isotopic dating of zircon is well and long …

Garnet could be the ultimate petrochronometer. Not only can you date it directly (with an
accuracy and precision that may surprise some), but it is also a common rock-forming and …

Mantle metasomatism is a relatively recent concept introduced in the early 1970s when
detailed studies of lithospheric mantle rock fragments (xenoliths), brought to the surface of in …

Rutile is an important carrier of high field strength elements (HFSE; Zr, Nb, Mo, Sn, Sb, Hf,
Ta, W). Its Zr content is buffered in systems with quartz and zircon as coexisting phases. The …

The timing of the final welding of the southern Altaids to construct Pangea is a matter of
debate which has led to considerable uncertainty regarding the configuration of northeast …

In this chapter, an overview of the findings to date from laboratory measurements of diffusion
of cations in the accessory mineral phases zircon, monazite, apatite, titanite (sphene) and …

Eclogites from the Earth's mantle found in kimberlites provide important information on
craton formation and ancient geodynamic processes because such eclogites are mostly …

A detailed petrological and geochemical study of low-temperature peridotite xenoliths from
Kimberley and northern Lesotho is presented to constrain the processes that led to the …

Estimation of burial rates and duration of prograde metamorphism of ultra-high-pressure
(UHP) rocks (T= 590–630° C, P= 2.7–2.9 GPa) of the Zermatt–Saas ophiolite from Lago di …

To investigate the systematics of the 176 Lu–176 Hf and 147 Sm–143 Nd garnet
chronometers, we performed REE and isotope analyses on garnet crystals of different size …
