Fundamentals of Luminescence Photo- and Thermochronometry
2019With its classic applications rooted in archaeology and sedimentology, the field of luminescence dating has, in the past decade, experienced a remarkable bloom of innovation and novel applications in Earth science. In the field of thermochronometry, luminescence has begun to successfully complement mainstream noble-gas and fission-track techniques, by ...

Bias in detrital zircon geochronology and thermochronometry
Chemical Geology, 2013Abstract Detrital studies that utilize zircon U–Pb geochronology and fission-track (FT) thermochronometry are subject to a range of potential sources of bias that should be properly evaluated and minimized. Some of them are common to any single-grain mineral analysis (e.g., variable bedrock mineral fertility, hydraulic sorting during transport ...

Low-Temperature Thermochronometry of Meteorites
Reviews in Mineralogy and Geochemistry, 2005Timing of accretion of the primary planetesimals in the early solar system has been investigated using short-lived (e.g., 26Al, 53Mn, 182Hf and 129I) and long-lived (e.g., 238U, 235U, 232Th and 147Sm) radionuclides. The first condensed objects in the solar system are known to be the calcium-aluminum-rich inclusions (CAIs) in chondrites ...

Zircon (U-Th)/He Thermochronometry
Reviews in Mineralogy and Geochemistry, 2005A number of features of zircon (ZrSiO4), including high U-Th concentrations, high abundance in a wide range of lithologies, refractory nature under metamorphic and some magmatic conditions, and resistance to physical and chemical weathering, make it highly suitable for geochronology and thermochronology and thus a versatile tool for examining a wide ...

In vacuo crushing experiments and K-feldspar thermochronometry
Earth and Planetary Science Letters, 1993Using in c, acuo crushing methods, both C1- and K-correlated components of trapped 4°At have recently been identified in hypersolvus alkali feldspar and K-feldspar-bearing 'chert' and stromatolite samples. If these components re-emerge during the late stages of thermal degassing, interpretation of 4°Ar/39Ar age spectra could be complicated.

Helium diffusion and low-temperature thermochronometry of apatite
Geochimica et Cosmochimica Acta, 1996To investigate the potential of the (U-Th)/He system for low-temperature thermochronometry, we have studied helium diffusion and have measured helium ages on Durango fluorapatite and on apatites from a gabbro and two tonalites from the Peninsular Ranges Batholith.

40Ar/39Ar thermochronometry of the Imataca Complex, Venezuela
Precambrian Research, 1989The Imataca Complex of Venezuela, an Archean metamorphic belt located on the northern margin of the Amazonian Craton, underwent upper amphibolite to granulite facies metamorphism during the 2.0 Ga Trans-Amazonian Orogeny. 40Ar/39Ar plateau dates on hornblende separates from the Imataca Complex vary from 1972 to 1760 Ma and record post Trans-Amazonian ...

Monazite Age Depth Profiling: Nm-Scale Thermochronometry
Mineralogical Magazine, 1998Significant capabilities of the ion microprobe for thermochronometric investigations of geologic materials remain largely unexploited. While spot analysis allows -5 lam scale imaging of Th-Pb age profiles in sectioned monazites (Harrison et al., 1997), the spatial resolution offered by depth profiling into the surface region of natural crystals is two ...

Quantum tunneling processes in feldspars: Using thermoluminescence signals in thermochronometry
Radiation Measurements, 2020Abstract During the past decade, our understanding of the nature of quantum tunneling processes in luminescence materials has been advanced significantly, by both experimental work and modeling insights into the underlying luminescence mechanism. This paper provides examples of analysis of thermoluminescence (TL) signals in feldspars, based on recent
