Thermoluminescence of ZrSiO 4 ( zircon ) : A new dating method ?
Zircon appears to be a suitable medium for thermoluminescence (TL) dating of sediments from the Quaternary. TL of zircon results predominantly from internal irradiation, due to the relatively high internal concentrations of a-emitting U and Th. The internal dose predominates over the external one that is caused by the surrounding geological layers and cosmic rays. Measurement of the TL buildup ...
متن کاملDeformation-induced trace element redistribution in zircon revealed using atom probe tomography
Trace elements diffuse negligible distances through the pristine crystal lattice in minerals: this is a fundamental assumption when using them to decipher geological processes. For example, the reliable use of the mineral zircon (ZrSiO4) as a U-Th-Pb geochronometer and trace element monitor requires minimal radiogenic isotope and trace element mobility. Here, using atom probe tomography, we doc...
متن کاملFundamentals of Noble Gas Thermochronometry
The ideal geochronometer would be a universally stable phase that quantitatively retains both parent and daughter isotopes. Though a few mineral systems such as zircon U-Pb dating come reasonably close to this ideal, most minerals are incompletely retentive of daughterproduct nuclides under crustal conditions. The mechanisms by which the daughter product can be lost from minerals include dissol...

متن کاملTopology-dependent thermoluminescence kinetics.
Standard kinetic models for thermoluminescence (TL) relate to the simple trap model (STM) and the model of localised transitions (LT). This paper presents a review of TL properties in various spatially correlated systems (SCS), which span the two limiting cases. A classification of kinetic models for SCS is proposed. Numerical results are presented for the isolated clusters model (IC) and the i...
