Secular change in metamorphism and the onset of global plate tectonics
On the contemporary Earth, distinct plate tectonic settings are characterized by differences in
heat flow that are recorded in metamorphic rocks as differences in apparent thermal …

Garnet: A rock-forming mineral petrochronometer
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 …
