A major limitation in rock art studies is that rock art can be difficult to date. The dating techniques currently in use fall into two broad categories: relative dating and absolute dating. Relative dating techniques include observations of patterns of chemical and physical weathering , evidence that art has been painted over, stylistic patterns, and variations in the spatial patterns of rock art indicating chronological sequences of site occupation. Absolute dating methods include analyses based on subjects depicted e. Occasionally, it has been possible to date rock art directly by chemically analyzing the organic materials that were used to draw it, for example, charcoal, plant fibers, and protein binders. A major problem with this approach, however, is that the sampling procedure damages the rock art to a certain extent. Dating technologies include standard radiocarbon dating, cation ratio analysis based on separate rates of leaching for the chemical constituents of desert varnishes , amino acid racemisation based on the decomposition rates of amino acids , optically stimulated luminescence based on the length of time that quartz grains have been removed from sunlight , lichenometry based on lichen growth rates , and micro-erosion analyses based on weathering patterns.
Dating Methods (Absolute and Relative) in Archaeology of Art
The recent establishment of a minimum age estimate of Tantalising excavated evidence found across northern Australian suggests that Australia too contains a wealth of ancient art. However, the dating of rock art itself remains the greatest obstacle to be addressed if the significance of Australian assemblages are to be recognised on the world stage.
A recent archaeological project in the northwest Kimberley trialled three dating techniques in order to establish chronological markers for the proposed, regional, relative stylistic sequence.
Using a highly refined form of carbon dating, researchers were able to Even more importantly, the techniques used to date the rock art can be.
Defining the subject and age of rock paintings can mean archaeologists are able to determine more about the life of prehistoric peoples and acquire a better understanding of our origins. However, dating rock art has been a struggle for archaeologists ever since the first discoveries of it in the late 19th century. It is possible to determine a number of things based on where the art is found and when it was found, but not everything can be learnt from that. Dating ancient material relies on the use of two approaches — direct or absolute and indirect or relative dating or chronology.
For example, consider relative dating.
If you would like to be involved in its development, let us know – external link. Scientists are revolutionising our understanding of early human societies with a more precise way of dating cave art. Instead of trying to date the paintings and engravings themselves, they are analysing carbonate deposits like stalactites and stalagmites that have formed over them.
This means they don’t risk harming irreplaceable art, and provides a more detailed view of prehistoric cultures. The researchers spent two weeks in Spain last year testing the new method in caves, and have just returned from another fortnight’s expedition to sample nine more caves, including the so called ‘Sistine Chapel of the Palaeolithic’, Altamira cave.
Mineral coatings, fringes, glazes and skins forming on the surfaces of sandstone rock shelters in Western Australia’s Kimberley region offer the potential to provide datable materials to bracket ages of rock art motifs with which they are often spatially associated. These mineral deposition systems, which occur at the interface between the atmosphere and host rock, have never been characterised specifically and their overall formation mechanisms have yet to be completely established.
This study serves to increase the understanding of complex processes behind the formation and long-term preservation potential of these mineral deposition systems. This is achieved by combining field observations with multiple mineralogical and geochemical characterisation techniques. Using both wet and dry season field observations and 94 mineral accretion samples collected from three different areas of the Kimberley, we identify four separate mineral deposition systems; polychrome fringes, dispersed wall coatings, floor glazes and silica skins.
Detailed observations of the different characteristics of each deposition system are used to assess their suitability for the application of radiometric dating methods. Coherent internal stratigraphies are identified in polychrome fringe accretions, essential for the reliable application of uranium-series dating techniques, whilst floor glaze mineralogy, identified as dominated by carbon-bearing calcium oxalate minerals, provides radiocarbon dating opportunities.
Consequently, this study provides a rigorous basis for establishing targeted sampling and analysis strategies essential for reliable and replicable rock art dating as well as having implications for rock art conservation.

A momentum of research is building in Australia’s Kimberley region, buoyed by the increasing local and international interest in the rich cultural heritage associated with our first Australians. My research focuses on understanding the complex formation mechanisms associated with mineral accretions forming on the walls and ceilings of rock art shelters. Often found to over and underlie rock paintings and engravings, once characterised, recent advances I have made in the application of radiogenic dating techniques to these accretions, are providing the first opportunity to produce maximum, minimum and bracketing ages for the associated rock art.
These ages are being used to anchor this rock art sequence to an absolute chronology and to integrate it into the emerging archaeological record of colonisation and settlement in northern Australia, increasing our understanding of Australia’s first people and helping to gain recognition for the Kimberley region as a heritage site of international significance.
This research has been based around extensive remote fieldwork in the Drysdale and King George River and Doubtful Bay regions of the Kimberley in northern Western Australia, working alongside local traditional owners and pastoral lease holders. I work in a large research team which includes a range of experts in archaeology and alternative dating techniques such as optically stimulated luminescence and cosmogenic nuclide dating.
Rock Art Dating and Its Importance in Landscape Archaeology
Radiocarbon dating has had a significant impact on rock art research, but an initial enthusiasm for this dating method by archaeologists has been replaced by a degree of scepticism. Radiocarbon dates undertaken directly on rock art or on associated mineral crusts have often reinforced such scepticism, in part because organic carbon-based materials are present in small quantities and their composition is of such variable composition that the technique is stretched to its limits.
For the researcher planning to obtain radiocarbon dates, it is essential to have an understanding of the dating options available, limitations of the technique, the potential impact of their own bias, and the value of a dating programme that is fully integrated within a larger project. This chapter outlines the various materials and methods used to radiocarbon date rock art.
Dating rock art can be problematic, especially for carvings. We do have indirect evidence to help us, however. Cup-and-ring carved rocks are sometimes found in prehistoric monuments with a known date, and this tells us that the carvings were created before or at the same time as the monuments. Researchers now believe that they were first created in the Neolithic period around years ago. This is supported by the discovery of cupmarked rocks in Neolithic monuments, such as the long cairn at Dalladies in Aberdeenshire, dating to BC.
Excavations of a rock art panel at Torbhlaren near Kilmartin, Argyll has also provided Neolithic dates from deposits on and around the rock surface, whilst in Northumberland, excavations of a carved rock at Hunterheugh revealed that an Early Bronze Age burial had been built over earlier, eroded motifs. You can read more about this research on our Other Research page. Many questions remain, however.
New Technique Shows San Rock Art Is 5,000 Years Old
December 7, A new technique, developed at ANSTO’s Centre for Accelerator Science, has made it possible to produce some of the first reliable radiocarbon dates for Australian rock art in a study just published online in The Journal of Archaeological Science Reports. The approach involved extracting calcium oxalate from a mineral crust growing on the surface of rock art from sites in western Arnhem Land, according to paper co-author research scientist Dr Vladimir Levchenko, an authority on radiocarbon dating using accelerator mass spectrometry.
Generally speaking, radiocarbon dating cannot readily be used to date Australian indigenous rock art directly, because it is characterised by the use of ochre, an inorganic mineral pigment that contains no carbon. The paper authors explain that carbon found in the mineral crusts on the rock surface was most probably was formed by microorganisms.
Mikkelsen ) summed up the methods used to date the Arctic rock-art. These are: Page 2. Acta Archaeologica. Fig. 1. Rock.
A new dating method finally is allowing archaeologists to incorporate rock paintings — some of the most mysterious and personalized remnants of ancient cultures — into the tapestry of evidence used to study life in prehistoric times. In the study, Marvin W. Rowe points out that rock paintings, or pictographs, are among the most difficult archaeological artifacts to date. They lack the high levels of organic material needed to assess a pictograph’s age using radiocarbon dating, the standard archaeological technique for more than a half-century.
Rowe describes a new, highly sensitive dating method, called accelerator mass spectrometry, that requires only 0. That’s much less than the several grams of carbon needed with radiocarbon dating. The research included analyzing pictographs from numerous countries over a span of 15 years. It validates the method and allows rock painting to join bones, pottery and other artifacts that tell secrets of ancient societies, Rowe said. Materials provided by American Chemical Society.

Chronology of rock art, ranging from Paleolithic to present times, is a key aspect of the archaeology of art and one of the most controversial. It was based for decades in nonscientific methods that used stylistic analysis of imagery to establish one-way evolutionary schemes. Application of scientific methods, also called absolute dating, started to be used in the s and since then has increased more and more its significance, as judged by the large number of papers published in the last two decades on this subject Rowe Absolute and relative dating methods have been used to establish tentative chronologies for rock art.
Relative dating refers to non-chronometric methodologies that produce seriation based on stylistic comparison and stratigraphic assumptions. On the other hand, absolute dating methods are based on scientific techniques that yield a chronometric age for a phenomenon in direct or indirect physical relation to rock art same age, older,
In fact, there have been two prior attempts to directly date BCS art at the Great Gallery through AMS radiocarbon methods. Successful AMS dating.
Rock art is a vital archaeological source to study and analyse the cognitive evolution of the human intellect across the world. The importance of rock art and its dating has long been a key issue of rock-art research and continues to be attended by difficulties about methodology, misinterpretation of findings and overconfidence in the reliability or precision of result. Most of the rock — art in their investigations for rock-art dating as present has been to establish chronologies of different rock — art sites.
The present volume mainly emphasis on long due and much discussed issues like that of what will be the suitable dating techniques for Indian rock art. This volume includes not only new insight but also new dating results. The data and interpretations put forward by various scholars are comprehensive and analytical. Most of their views are appropriate and hold promise in terms of recent trends in dating rock art. His area of interest is both classical and vernacular traditions.
