“…The history of cooling and exhumation of intrusive igneous bodies (cf. Harrison and Clarke, 1979;Hurford, 1986;England and Molnar, 1990;Foster et al, 1992;George, 1993;Caggianelli et al, 2000;Parada et al, 2005;Glorie et al, 2017;Bernet et al, 2019;Nieto-Samaniego et al, 2019) can be determined by constructing cooling curves or paths, thereby assessing the temperature, time and depth variables that characterize the body from its initial emplacement to its final exposure on the surface (Figures 1 and 2).…”

In general, this cooling is generated as rocks move toward the surface through exhumation events resulting from erosion processes or tectonic activity (cf.…”

“…In recent decades, different radiometric dating techniques have been combined to construct cooling curves or paths in rock bodies (since isotopic systems are essentially a form of geothermometry) in order to understand the dynamics of orogenic belts and sedimentary basins, as well as their relationships with mineral deposits and petroleum systems (cf. Zeitler, 1985;Green, Duddy, Gleadow et al, 1989;Hunziker et al, 1992;Gallagher et al, 1998;McInnes et al, 1999;Armstrong, 2005;Bernet et al, 2006, Peyton andCarrapa, 2013 a, b;Bernet et al, 2019).…”

“…Zeitler et al, 1982;Bernet et al, 2006;Deeken et al, 2006;Peyton and Carrapa, 2013a); however, exhumation processes are also related to erosion and climatic effects, as well as the combination of these processes to a greater extent (cf.

The present study reviews radiometric and thermobarometric techniques used to construct cooling curves or paths to characterize intrusive bodies and to calculate cooling and exhumation rates. To construct these curves or paths, the temperature, time and depth variables must be estimated in intrusive bodies by applying various analytical techniques, including thermobarometry and U-Pb zircon, Ar-Ar hornblende and muscovite, fission track and (U-Th)/He zircon and apatite dating, in combination with a geological framework of reference for each intrusive body. The authors recommend to determine the crystallization age by zircon U-Pb dating, to quantify the emplacement depth using thermobarometry methods according to the composition of the intrusive body, to calculate the initial cooling ages with hornblende and muscovite Ar-Ar methods, as well as to calculate the cooling/exhumation ages in the upper crust using low-temperature thermochronology methods. These cooling curves or paths in intrusive bodies are highly relevant when studying compressive or extensional areas because they partly represent the thermal history of the era, thereby providing data on the magmatic and tectonic evolution of the region. Thus, these studies are highly important for designing geodynamic models and for their possible application in developing the tectonic model of the country.

Detrital thermochronology studies based on the lag-time approach are increasingly employed to investigate the erosional evolution of mountain belts and perform paleotectonic reconstructions starting from the analysis of sedimentary rocks. However, simple predictions of lag-time conceptual models are often in conflict with observations in sedimentary basins. In this review article, we discuss the major assumptions of the lag-time approach, and present conceptual models to illustrate the main factors that may influence the final complexity of the detrital thermochronologic record in a sedimentary basin. These factors include: (i) the original complexity of the thermochronologic age structure in the source region; (ii) mixing of detritus from multiple source regions characterized by different geologic evolution; (iii) modifications of the original thermochronologic fingerprint from source to sink; (iv) potential post-depositional annealing due to thick sedimentary burial. Based on this synthesis and discussion, we present a list of interpretive guidelines and fundamental criteria for the geologic interpretation of the detrital thermochronologic record derived from the erosion of single and mixed sources. These interpretive guidelines are then applied to published detrital thermochronology datasets from the European Alps, Taiwan and the Himalayas in order to illustrate benefits and pitfalls of the geologic interpretation of thermochronologic age trends through a stratigraphic succession. Results provide evidence for (i) non-steady-state exhumation of the European Alps, (ii) late Miocene onset of arc-continent collision in Taiwan, and (iii) late Miocene morphogenic phase of mountain building in the Himalaya. Concepts presented in this article reinforce existing approaches and provide new perspectives for the application of the detrital thermochronologic approach to tectonic settings where the geologic evolution may be poorly understood. As such, they are expected to guide geologists towards interpretations that are both consistent with evidence provided by different thermochronologic systems, and geologic evidence provided by the rock record.
