Rutile is the most common naturally occurring titanium dioxide polymorph and is widely
distributed as an accessory mineral in metamorphic rocks ranging from greenschist to …

Titanite (CaTiSiO5) is a common mineral in calc-silicates, metamorphosed igneous rocks,
and calc-alkaline plutons. The mineral was first named by Martin Klaproth in 1795 for its high …

Zircon and rutile are common accessory minerals whose essential structural constituents, Zr,
Ti, and Si can replace one another to a limited extent. Here we present the combined results …

Diffusion of Pb was characterized in natural and synthetic zircon under a range of
conditions. In most experiments, mixtures of Pb sulfate and ground zircon were used as the …

Ocean microstructure data show that turbulent mixing in the deep Brazil Basin of the South
Atlantic Ocean is weak at all depths above smooth abyssal plains and the South American …

This substantially revised edition includes recently published information relating to plate
tectonics and continental origin. A large number of new figures have been added, and new …

Apatite is a common U-and Th-bearing accessory mineral in igneous and metamorphic
rocks, and a minor but widespread detrital component in clastic sedimentary rocks. U–Pb …

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 …

Geothermics is an area of geophysics that studies the thermal state and history of the interior
of the Earth. Solar heat penetrates only into the topmost layers of the Earth's crust. Diurnal …

Useful U–Pb isotopic data may be obtained from sphene (or titanite, CaTiSiO5) because:(1)
it is a widespread accessory mineral,(2) it can incorporate uranium in its structure, and (3) it …
