Print cover Page. The aim of this study was to determine whether the ancient bricks from Sungai Batu Temple SB1 are made from local materials or not. Chronometric and relative dating have given different results, the absolute dating gave the date between 2 nd to 3 rd century AD while the relative dating gave the date between 6 th to 7 th century AD. The structure which was fully built using bricks is a relatively large stupa structure and not a structure associated with animism practised. Analysis shows that the mineral content present in the ancient brick samples consists of quartz, muscovite, microcline, mullite and albite.

The nondestructive nature of the XRF-measurement permitted a comparative study of dating methods by sequentially applying chemical dating. We presents the results of a radiocarbon dating and XRF (X-ray Fluorescence) measurements performed on organic samples and pottery recovered from “Grotta .

Click here for to receive additional information and expert advice on the use of handheld XRF analyzers for archaeometric and archaeological science purposes. Archaeometry—also known as archaeological science—is the application of scientific methods and techniques to archeological investigation. The field of archaeometry has been quickly expanding and adopting new methodology over the last several decades, as the sophistication and availability of technology and instrumentation grow, while the cost of scientific analysis has been slowly but surely dropping. Many scientific instruments that produce data such as molecular or elemental composition, chromatography, carbon dating, etc. As technology continues to improve in price, user-friendliness, and data reliability, archeological science will continue to expand and stands to significantly supplement already existing and traditional methods in archaeological investigation.

X-ray fluorescence XRF is the emission of characteristic "secondary" or fluorescent X-rays from a material that has been excited by being bombarded with high-energy X-rays or gamma rays. The phenomenon is widely used for elemental analysis and chemical analysis , particularly in the investigation of metals , glass , ceramics and building materials, and for research in geochemistry , forensic science , archaeology and art objects [1] such as paintings [2] and murals.

Precious corals are some of the most valuable living marine resources, growing and commercially exploited only in limited areas of the world, namely the Mediterranean Sea and the Northern Pacific Ocean. Their skeleton is formed by calcium carbonate crystallized in the form of calcite whereas their color is because of the presence of partially demethylated polyene pigments.

This is the first laminated sediment sequence recorded in the region. However, visual counting of the layers was restricted due to partial indistinctness of the lamination. In order to confirm the annual sedimentary cyclicity and proceed with annually resolved data, in addition to the visual identification we used high-resolution geochemical markers.

In this work, a terra-cotta brick collected from the famous archaeological Roman city Cuicul , Algeria, was successfully dated by thermoluminescence. The provenance of the fabrication material was also identified by X-ray fluorescence analysis XRF. The results obtained show that the brick was probably made in A. This date is in good agreement with the history of the dated site and the neighborhood Caracalla arch edified in honour to Caracalla emperor — A. The XRF study demonstrates that the raw clay used for the fabrication of the brick is local and well selected by the Roman builders.

These results and complementary studies on the manufacturing techniques employed for making these objects will contribute to our knowledge of metalworking, trade, as well as the transfer of ideas and technologies at Ephesus and in Western Asia in the Archaic period. The objects can be characterized as homogeneous alloys, mainly consisting of gold Au , silver Ag and copper Cu. A high compositional variation of Au and Ag between different objects could be determined Au between Plus de 80 objets anciens en or p. Within the Archaic period, the Artemision is unique in terms of the large number and variety of gold jewellery. No other sanctuary from this period has yielded a similar wealth of gold objects. During the British and Austrian excavation campaigns at this site, a small number of figural objects, such as statuettes in human or animal form and miniature objects, were found. They were deposited in the sanctuary as votive gifts.

X-ray fluorescence is a widely used technique for the analysis of major, minor, and trace elements. XRF is physically based on the excitation of atoms with X-rays and the detection of secondary characteristic X-rays emitted by the sample. This analysis technique is non-destructive and requires no chemical digestion. Metal objects, glassware, enamels, gemstones and other inorganic materials can be analyzed non-invasively without taking samples. Due to alteration and corrosion of metal objects, for example, the composition of the surface layer differs often from the original unaltered metal. For this reason it is always better to take samples from the inner metal core with a small drill and analyze the drillings with XRF.
