High‐Titanium Zircon Rims in Rhyolite – A Reflection of Adiabatic Ascent?

Geological Journal, EarlyView.
The ascent of granitic magma from source to emplacement is rapidly achieved through dyking, resulting in negligible heat loss to the surrounding wallrock (i.e., adiabatic). Zircon growth during ascent can record the changing magma conditions including adiabatic cooling and heating, resulting in high titanium rims on low titanium cores without ...
