The aim of this chapter is to present the K-Ar and Ar-Ar dating techniques in the context of
noble gas studies, since there are already several recent texts on K-Ar and Ar-Ar dating …

Because monazite is extremely rich in U and Th, radiogenic Pb (∗ Pb) accumulates very
quickly, and reaches, in about 100 Ma, a level where it is possible to analyse it with the …

The temperature-time significance of 40 Ar/39 Ar muscovite ages is difficult to evaluate
quantitatively because of ambiguities in the choice of an appropriate model diffusion …

It remains controversial whether burial and exhumation in mountain belts represent episodic
or continuous processes,,,,,,,,,,,,,,,,,,,. Regional patterns of crystallization and closure ages of …

The southern Dora Maira massif consists of several continental crustal slices differing in their
metamorphic grade, separated and themselves dissected by major low-angle faults. In the …

Geochronological investigations in high-and ultra-high-pressure metamorphic rocks are
problematic since firstly the low temperatures lead to fine grain size and disequilibrium …

Abstract The Dora‐Maira massif is an archetypal nappe stack of subducted and exhumed
upper crust. Slices of continental crust experienced metamorphism at upper blueschist to …

40Ar 39Ar data for white micas from quartzite mylonites from a thrust system are evaluated
with respect to whether the minerals record cooling ages or, alternatively, ages of …

The Pressure–Temperature–time–deformation evolution of the high-to ultra-high-pressure
units of the Western Alps has been progressively refined in the last 40years, leading to …

Recent developments in microanalytical tools such as the ion and laser microprobe have
revealed spatial distributions of radiogenic isotopes in minerals which cannot be explained …
