The landscape surrounding the Neolithic monument contains many secrets, with features dating back to much earlier times. Having surveyed more than 18 square kilometres in the vicinity, archaeologists continue to make surprising discoveries. The latest, a series of deep pits forming a vast circle more than two kilometres in diameter, shows how technology makes it possible to peer even further back into time. Along with their shovels, trowels and brushes, archaeologists have put together a toolbox of new technologies. These were thought to be old filled-in ponds. But ground-penetrating radar, another archaeological tool, raised questions about that notion. This technique, which reflects radio waves off underground structures, showed that far from being shallow, as ponds would have been, the anomalous features had deep vertical sides.

Testing feldspar and quartz luminescence dating of sandy loess sediments from the Doroshivtsy site (Ukraine) against radiocarbon dating. Amsterdam [u.a.].
Las Vegas, N. Some research applications include determining how long a sample of sediment has been buried or the time since a clay pot was fired. With thermal luminescence dating, the samples are heated in order to give off light. Sammeth said there are many research applications for the new instruments, ranging from dating sediments in a dried up lake bed to dating an archaeological artifact like a pot shard.
During a sabbatical fall semester , Sammeth gained hands-on experience using the time- dating instruments for research. He added that the new instruments at Highlands will be used to cross-reference other chronological dating techniques such as carbon dating and dendrochronology — tree ring dating. Sammeth plans to develop a luminescence dating course with a laboratory component where students will learn how to use the new instruments.
He said the lab will also offer new opportunities for both undergraduates and graduate students to conduct their own research.

Ideally situated along the lake of Geneva, near Lausanne city center, its campus brings together over nationalities. To complete the team, the Institute of Earth Surface Dynamics of the Faculty Geoscience and Environment of the University of Lausanne is looking for a Post-doctoral position in the geomorphology of mountain debris covered glaciers. The position is focussing on understanding the geomorphology of debris-covered glaciers.
The project will use a combination of recently developed luminescence rock surface exposure dating and dynamic glacier modelling that includes the feedbacks between debris transport and mass balance. The targeted field-site will be Miage Glacier, Aosta valley, Italy. Whilst all glaciers transport sediment, it remains unclear why some develop extensive supraglacial debris. Most mountain glaciers are shrinking rapidly in response to climate change, and debris-covered glaciers are expected to have a longer life expectancy than equivalent clean-ice glaciers because supraglacial debris insulates the underlying ice.
However, until we can quantify the processes controlling their behaviour, it is not possible to accurately predict how debris-covered glaciers will evolve under a changing climate. Results from this project will enhance understanding of the contribution of mountain glaciers to the sustainability of water resources in vulnerable catchments such as those in High Mountain Asia and South America.

Luminescence dating refers to a group of methods of determining how long ago mineral grains were last exposed to sunlight or sufficient heating. It is useful to geologists and archaeologists who want to know when such an event occurred. It uses various methods to stimulate and measure luminescence.
The work is based on radiocarbon dating of mud wasp nests, uranium-series radionuclide dating of rock falls and optically stimulated luminescence dating of.

Introduction How do we measure the OSL signal? How do we measure the radiation dose rate? Another way of dating glacial landforms is optically stimulated luminescence dating OSL. OSL is used on glacial landforms that contain sand, such as sandur or sediments in glacial streams. The OSL signal is reset by exposure to sunlight, so the signal is reset to zero while the sand is being transported such as in a glacial meltwater stream.
Once the sand grain has been buried and it is no longer exposed to sunlight, the OSL signal starts to accumulate.

Over the last 60 years, luminescence dating has developed into a robust chronometer for applications in earth sciences and archaeology. The technique is particularly useful for dating materials ranging in age from a few decades to around ,—, years. In this chapter, following a brief outline of the historical development of the dating method, basic principles behind the technique are discussed. This is followed by a look at measurement equipment that is employed in determining age and its operation.
Luminescence properties of minerals used in dating are then examined after which procedures used in age calculation are looked at. Sample collection methods are also reviewed, as well as types of materials that can be dated. Continuing refinements in both methodology and equipment promise to yield luminescence chronologies with improved accuracy and extended dating range in the future and these are briefly discussed.
Luminescence – An Outlook on the Phenomena and their Applications. Luminescence dating refers to age-dating methods that employ the phenomenon of luminescence to determine the amount of time that has elapsed since the occurrence of a given event. In this chapter, the application of luminescence techniques in dating geological and archaeological events is examined.

Luminescence dating including thermoluminescence and optically stimulated luminescence is a type of dating methodology that measures the amount of light emitted from energy stored in certain rock types and derived soils to obtain an absolute date for a specific event that occurred in the past. The method is a direct dating technique , meaning that the amount of energy emitted is a direct result of the event being measured. Better still, unlike radiocarbon dating , the effect luminescence dating measures increases with time.
As a result, there is no upper date limit set by the sensitivity of the method itself, although other factors may limit the method’s feasibility. To put it simply, certain minerals quartz, feldspar, and calcite , store energy from the sun at a known rate. This energy is lodged in the imperfect lattices of the mineral’s crystals.

The Liverpool Luminescence Laboratory is a world-class research facility with the capabilities to perform cutting-edge luminescence dating techniques for determining the timing of sediment deposition or exposure. Please e-mail Dr Smedley rachel. Luminescence dating is a geochronological technique that can determine the timing of sediment deposition using quartz or feldspar.
It relies upon the fundamental principle that mineral grains can store and release energy produced by radioactive decay. The radioactive decay of K, Rb, U and Th emits energy in the form of alpha and beta particles, and gamma rays, which exposes grains to an environmental dose-rate, in addition to the dose provided by the cosmic rays. This energy recharges the battery over time during burial.
Defects or impurities in the crystal lattice of quartz or feldspar grains trap electrons, which are then excited and released when stimulated by light or heat. We can then determine the time elapsed since the grain was last exposed to light or heat by measuring how much energy is stored in the grain today and dividing it by the environmental dose-rate it was exposed to throughout burial. Luminescence dating is a versatile technique and can be advantageous over other geochronological techniques as: 1 it directly determines the timing of sediment burial or exposure; 2 it can be used in many depositional settings e.
