New Light on Stonehenge

Samples for luminescence dating can be collected in a myriad of ways, and can include different types of material. Materials most commonly dated are grains of sand or silt, however pottery, rock surfaces, rock art, and even archaeological constructions, such as walls and buildings have also been sampled. Because luminescence dating methods determine the last time a mineral has been exposed to light or heat , it is imperative that light or heat is not introduced to the sample during the sampling process. This can be tricky! Below we list some common, and not so common ways of collecting luminescence samples. Stay tuned for upcoming blogs that delve into more details about the sampling process. This is the most common method of collecting a luminescence sample from sediments.

I don’t think the following is common knowledge yet, despite the fact that the research is already some years old. The Surface Luminescence Dating method has been used in to date some Egyptian Monuments; an article about the results can be found here. At the site of this uninscribed temple pottery from the Old Kingdom untill the Ptolomaic Period was found. A limestone sample of the temple however indicates an even older date than the OK and places it in Predynastic times!

It is rather amusing that despite ceramic sequencing, preserved papyri, radiocarbon dating, luminescence dating, and a number of other data sets, there are still those who would contest the conventionally understood datings. Why, Swede, that’s just because it’s all wrong. Science is always being proved wrong.

I think fringes and pseudo-archeologists have been really giving hard times to Egyptologists. So much money has been spent to convince the so-called fringe group! Today,the traditional theory prevails,that is Giza was built as a funerary complex for the 4th Dynasty pharaohs. The Old Kingdom monuments are a mystery and conventional dates has been questioned and critically discussed. We will have to consider the worst case for all of the three to fit the accepted chronology, and then also it will hardly fall into the bracket.

Looks like, pretty much for all monuments we will have to rely upon the worst deviation from the Luminescence dating. Thankfully, there are big deviation bands to support the archeological dates.


Ever since The Enlightenment, and possibly even before that, researchers have attempted to understand the chronology of the world around us, to figure out precisely when each stage in our geological, biological and cultural evolution took place. Even when the only science we had to go on was religious literature and the western world believed the world was created in BC 1 , scholars tried to figure out when each biblical event took place, to define a chronology from savagery to civilization, from creation to the first animal, then to the emergence of the first people.

The pre-enlightenment understanding of our geological and cultural history may now be proven wrong and subject to ridicule, but the principles of defining our place in time in the cosmos underpin many sciences.

Dates are determined by a variety of processes, including chemical analyses as in radiocarbon dating and thermoluminescence , data correlation as in dendrochronology , and a variety of other tests.

The DosiVox programme is used to reconstruct radiation transport in complex depositional environments. Using two archaeological case studies from ancient Egypt, the burial environments for a selection of ceramic vessels are reconstructed using the DosiVox programme, allowing the simulation of the emission and transport of radiation throughout these burial environments. From this simulation we can extract the external dose rate of the archaeological samples, a measurement necessary for determine a luminescence age.

We describe in detail how DosiVox can be used to best advantage at sites with complex depositional histories and highlight that DosiVox is a valuable tool in luminescence dating. This work illustrates that DosiVox is, at present, unparalleled in reconstructing a more accurate and detailed external gamma dose rate which can significantly improve upon simplistic scaled geometric models.

Luminescence dating, including optically stimulated luminescence OSL dating, is a valuable tool to archaeologists and geologists and remains arguably the best technique for the chronometric dating of archaeological or geological materials comprised of quartz and feldspar. In this manner, in archaeology, luminescence dating is widely applicable to pottery, minerogenic building materials and ceramic objects or sediments from archaeological contexts.

While dating of recently excavated material can be routine as in situ sampling can be done by a trained luminescence specialist aware of precisely what samples and measurements are required to achieve a luminescence age , working with more complex material, such as that recovered from museum contexts, can be more difficult. While working with recently recovered material suitable for OSL sampling is of course ideal, it is not always possible and in many cases OSL dating is not permitted, owing to strict archaeological laws which coincide with a lack of accessible laboratory facilities.

Archaeological materials housed in museums—most notably pottery vessels and ceramic objects—were often not collected with OSL dating in mind and in some cases were excavated and placed in collections well before OSL dating was even developed.

Research article 07 May Correspondence : Galina Faershtein galaf gsi. Optically stimulated luminescence OSL of quartz is an established technique for dating late Pleistocene to late Holocene sediments. Recent developments in new extended-range luminescence techniques show great potential for dating older sediments of middle and even early Pleistocene age.

Dose recovery and bleaching experiments under natural conditions indicated that the pIRIR signal is the most suitable for dating the Nilotic feldspar. Dating clastic sediments of Pleistocene age, particularly of middle and early Pleistocene, is an ongoing challenge.

radiocarbon and luminescence dating have been the most frequently be adsorbed to the brick surface during firing under reducing They have been used for dating buildings via radiocarbon from some timber to date buildings [​26], as has probably occurred in studies dating the Pyramids of Egypt [27].

The age of the Egyptian pyramids has long been a contentious subject and dating evidence is minimal, subjective and speculative at best. Can we take the radiocarbon dates of organic particles found between the stones of the pyramids as evidence for when the stones were put into place? Is the Diary of Merer, the papyrus fragment from the time of Khufu actually talking about transporting stone to build the Great Pyramid, or some other structure at Giza?

This is the type of evidence we have to work with when proving the age of the Great Pyramid, but to say the pyramids are far older than the 4th dynasty is no different than saying the Great Pyramid was created by Khufu. Where is the evidence? I am open to all interpretations, even the mainstream view, but we need to gather the evidence, however circumstantial, if we wish to find out the true age of the pyramids.

Radiocarbon tests of carbonized plant remains where artifacts were unearthed last May along the Savannah River in Allendale County by University of South Carolina archaeologist Dr. Albert Goodyear indicate that the sediments containing these artifacts are at least 50, years old, meaning that humans inhabited North American long before the last ice age.

The findings are significant because they suggest that humans inhabited North America well before the last ice age more than 20, years ago, a potentially explosive revelation in American archaeology. Goodyear, who has garnered international attention for his discoveries of tools that pre-date what is believed to be humans’ arrival in North America, announced the test results, which were done by the University of California at Irvine Laboratory, Wednesday Nov.

In half a century, global warming has widened the Batagay megaslump from a small gully to a yawning pit more than meters wide. On a spring day in , Alexander Kizyakov rappelled down the meter headwall of the Batagay megaslump in eastern Siberia, pausing to chisel out chunks of ice-rich soil that had been frozen for eons.
