Apatite's ubiquity in crystalline rocks, variable trace element contents (particularly with
regard to the REE, actinides and Sr), and amenability to various dating techniques based on …

Zircon is the main mineral in the majority of igneous and metamorphic rocks with Zr as an
essential structural constituent. It is a host for significant fractions of the whole-rock …

The Th/U ratios of zircon crystals are routinely used to help understand their growth
mechanism. Despite the wide application of Th/U ratios in understanding the geological …

At low temperatures (< 750 C at moderate to high crustal pressures), the production of
sufficient melt to reach the melt connectivity transition (∼ 7 vol%), enabling melt drainage …

Crust extracted from the mantle in arcs is refined into continental crust in subduction zones.
During sediment subduction, subduction erosion, arc subduction, and continent subduction …

Arc magmas and the continental crust share many chemical features, but a major question
remains as to whether these features are created by subduction or are recycled from …

Formation of continental crust has shaped the surface and interior of our planet and
generated the land and mineral resources on which we rely. However, how the early …

This chapter focuses on phosphates that are significant in metamorphic rocks. A quick
survey of phosphate mineral descriptions at a commercial mineral web-site revealed over …

Ages retrieved from accessory minerals in high-grade metamorphic rocks place important
constraints on the timing of events and the rates of tectonometamorphic processes operating …

We report measurements of Pb diffusion in both synthetic (CePO4) and natural monazites
run under dry, 1-atm conditions. Powdered mixtures of prereacted CePO4 and PbZrO3 were …
