1 Airaghi, Laura; Warren, Clare J.; de Sigoyer, Julia; Lanari, Pierre and Magnin, Valérie (2018). Influence of dissolution/reprecipitation reactions on metamorphic greenschist to amphibolite-facies mica ⁴⁰Ar/³⁹Ar ages in the Longmen Shan (eastern Tibet). Journal of Metamorphic Geology (Early Access).

Co-Authored by Clare Warren and using data collected by lead author Laura Airahgi in the Ar Lab at the Open University, this paper looks at metamoprhic rocks from eastern Tibet and uses a combination of techniques to look at there metamorphic history. One finding from the paper is that the Ar record of the micas in the studies low to medium grade rocks appears controlled mainly by dissolution-reprecipiation processes rather than diffusive loss.

This paper uses new Ar ages and plant fossil archives to understand the uplift history of the southeastern margin of Tibet in the latest Eocene, with a surface height of part of the margin to be ~3 km and rising at ~34Ma and possibly reaching the present 3.9Km elevation in the early Oligocene.
