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.

Metrics details. The scientific imaging of works of art is crucial for the assessment of the presence and distribution of pigments and other materials on surfaces. Indeed, the unique near-infrared luminescence emission of Egyptian blue allows the imaging of its distribution on surfaces. We focus on the imaging of the time-resolved photoluminescence of ancient Egyptian objects in the Burri Collection from the Civic Museum of Crema and of the Cremasco Italy.
For the first time we provide data on the photoluminescence lifetime of Egyptian blue directly from objects. Moreover, we demonstrate that the use of a pulsed laser emitting at two different wavelengths increases the effectiveness of the lifetime imaging technique for mapping the presence of emissions from pigments on painted surfaces.

We’ve shared a few insights into the monumental limestone we’ve been Searching for IR luminescence pointed us to a tiny area of inlay in the One way to assess surface discolorations is ultraviolet (UV) light Investigating the use of the Nd:YAG laser to clean ancient Egyptian polychrome artifacts.
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.
The dawn of modern homo sapiens occurred in Africa between 60, and 80, years ago. Evidence of modern man’s migration out of the African continent has been documented in Australia and Central Asia at 50, years and in Europe at 40, years. The fact that humans could have been in North America at or near the same time is expected to spark debate among archaeologists worldwide, raising new questions on the origin and migration of the human species.

Portions of a supposedly highly advanced unknown lost civilization none other than Atlantis living on Antarctica at the time were able to survive the destructive cataclysms and go on to convey their knowledge to the builders of the megalithic structures of Egypt, Maya, Babylon, and other known great civilizations. He also claims that the Mayan calendar portended world cataclysms in In Magicians , Hancock now says he got it all wrong—there was no crustal shift; instead he thinks this advanced civilization was destroyed by a comet.
Magicians appears to be on its way to becoming another bestseller for the British writer. Although Hancock has few scientific credentials an undergraduate degree in sociology from Durham University , 4 his early career as a journalist 5 helped him navigate through a wide range of scientific research, but without benefit of specialized training in astronomy, geology, history, archaeology, or comparative religion and mythology.
Hancock is obviously bright, articulate, and a good writer and storyteller who comes across as eminently reasonable, which makes it all the more difficult to tease apart fact from fiction in the many claims made in his books, documentary films, and lectures. Two large T-shaped pillars over 5m 16 feet high typically stand in the middle of the ring with smaller pillars facing them.
Some of these stones are decorated with reliefs of animals that once lived in the area. This area known as Enclosure D features birds, while others emphasize animals such as snakes, foxes, boars, or wildcats. Unfortunately for Hancock these people left behind no hard evidence for their existence, so he is forced to allude to what he thinks is sophisticated architecture, along with a few carved figures that he asserts represent astronomical constellations.
The site, he says, was used from 11, to about 10, years before the present.

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. As technology advances, so do our methods, accuracy and tools for discovering what we want to learn about the past.
For example, astronomy uses some relative dating methods to calculate the age of the Luminescence/Thermoluminescence: This measures the amount of light emitted It states that lower surface layers in a sequence must have been deposited first He developed the relative dating method during his studies in Egypt.

Luminescence dating has a proud history of association with archaeology, beginning almost half a century ago. The subsequent decades of research have seen a range of archaeometric applications of luminescence dating: from fired pottery and burnt flints to sediments incorporated into occupation deposits and earthen constructions.
Important contributions have been made to topics as diverse as modern human origins, continental colonisations and the dating of prehistoric rock art. View via Publisher. Save to Library.
All of these factors lead to the formation of altered surface layers, then damaging the original stone components. Here, red weathering, one of the most aggressive deterioration forms affecting one of the most famous archaeological sites in the world Un-finished Obelisk in Aswan was investigated and evaluated through different analytical techniques. Binuclear Microscop and SEM were used to evaluate the optical and morphological features of the highly deteriorated samples.

We show that the palaeochannel is a former course of the Sutlej River, the third largest of the present-day Himalayan rivers. Indus urban settlements thus developed along an abandoned river valley rather than an active Himalayan river. Alluvial landscapes built by large perennial rivers form the environmental templates on which the earliest urban societies nucleated 1 , 2. Large-scale spatiotemporal settlement patterns in early urban societies are postulated to have been influenced by river migration across alluvial floodplains 1 , 3 , 4.
On long time scales, rivers migrate by episodic, relatively abrupt changes in their course called avulsions 5. Avulsions lead to diversion of river flow into new or abandoned channel pathways on floodplains 5 — 7. They are stochastic events that typically occur at century to millennial timescales 8.
