TL;DR: Portable X-ray fluorescence (PXRF) serves as an effective, rapid and non-destructive, method for determining the elemental composition of natural and man-made materials, such as ceramic, glaze, glass, obsidian, pigments, paint, and metal artifacts.
Abstract: Portable X-ray fluorescence (PXRF) serves as an effective, rapid and non-destructive, method for determining the elemental composition of natural and man-made materials, such as ceramic, glaze, glass, obsidian, pigments, paint, and metal artifacts; based on the analysis, the determination of their origin, technological and production issues, comparative studies, and more knowledge in the field of cultural heritage can be aimed at. The wavelengths of the released energy, known as fluorescent X-rays, are detected and measured by spectrograph in the energy dispersive and wavelength manner of detection. Since only the surface of an object is studied, in dimensions that typically range within some millimeters, care needs to be taken that corrosion and decay do not affect the analysis. A world survey of the major applications of PXRF in the analysis of various cultural material types is reported, and the available PXRF setups are described. A review of the results of obsidian characterization and clustering is included, and the advantages, reliability, and limitations are discussed, with particular emphasis on the calibration procedures.

TL;DR: In this article, the authors used secondary ion mass spectrometry (SIMS) to accurately define the hydration profile by modeling the profile of the surface hydrogen concentration versus depth, the age determination is reached via equations describing the diffusion process.
Abstract: About fifty years ago Friedman and Smith [1] recognized the obsidian hydration phenomenon and proposed an empirical dating method based on the conversion of the optically measured hydration depth to an absolute age They and subsequent researchers developed distinct versions of obsidian hydration method consisting of both empirical rate and intrinsic rate development, thus refining the method However, in spite the accurately measured rinds beyond digital optical microscopy employing infrared spectroscopy and nuclear analysis, the traditional empirical age equation produce occasionally satisfactory results but still fail to produce a reliable chronometer In the last ten years, secondary ion mass spectrometry (SIMS) has been employed to accurately define the hydration profile By modeling the profile of the surface hydrogen concentration versus depth the age determination is reached via equations describing the diffusion process Finite difference modeling and essential assessments of the novel SIMS-SS (surface saturation) phenomenological method produce a sound basis for the new diffusion age equation and provides promising results This review refers on the development of obsidian hydration dating (OHD) and diffusion process in glass and reckons future directions of SIMS applications in obsidians

TL;DR: The surface luminescence (thermoluminescence, TL or OSL) dating has been developed and further refined on various aspects of equivalent dose determination, complex radiation geometry, incomplete bleaching etc.
Abstract: Daylight radiation resets luminescence ‘clock’ to zero on rock surfaces, but transmission depends on the transparency of the rock. On burial, surfaces are no longer exposed to daylight and accumulation of trapped electrons takes place till the excavation. This reduction of luminescence as a function of depth fulfils the prerequisite criterion of daylight bleaching. Thus rock artefacts and monuments follow similar bleaching rationale as those for sediments. In limestone and marble, daylight can reach depths of 0.5–1 mm and up to 16 mm respectively, while for other igneous rocks e.g. quartz in granites, partial bleaching occurs up to 5mm depth under several hours of daylight exposures and almost complete beaching is achieved in the first 1 mm within about 1 min daylight exposure. The ‘quartz technique’ for limestone monuments containing traces of quartz enables their dating with Optically Stimulated Luminescence (OSL) techniques. The surface luminescence (thermoluminescence, TL or OSL) dating has been developed and further refined on various aspects of equivalent dose determination, complex radiation geometry, incomplete bleaching etc. A historical review of the development including important applications, along with some methodological aspects are discussed.

TL;DR: In this article, a nouvelle methode de thermoluminescence (TL) was proposed for dater les pierres megalithiques sculptees de Mycenes et Helleniko (dans le Peloponnese, Grece).
Abstract: Nous avons developpe une nouvelle methode de thermoluminescence (TL) pour dater les pierres megalithiques sculptees de Mycenes et d'Helleniko (dans le Peloponnese, Grece). Les resultats de notre premiere approche, fondes sur le principe de photodesexcitation, semblent encourageants. Des doses TL totale ont ete mesurees entre 11-17 Gy, tandis que l'âge de l'enceinte de Mycenes (vers 1280 av. J-C) est compatible avec les estimations de notre nouvelle methode
