Traveling along the time line: Geological dating methods

Sloss, C. An introduction to dating techniques: a guide for geomorphologists. Kennedy Eds. London: Elsevier Inc. This chapter provides researchers with a guide to some of the types of dating techniques that can be used in geomorphological investigations and issues that need to be addressed when using geochronological data, specifically issues relating to accuracy and precision. This chapter also introduces the ‘types’ of dating methods that are commonly used in geomorphological studies. This includes sidereal, isotopic, radiogenic, and chemical dating methods.

Classic and new dating methods for assessing the temporal occurrence of mass movements

Overall, this book focuses on the current understanding of the dynamic interplay between surface processes and active tectonics. As it ranges from the timescales of individual earthquakes to the growth and decay of mountain belts, this book provides a timely synthesis of modern research for upper-level undergraduate and graduate earth science students and for practicing geologists.

Additional resources for this book can be found at: www. Robert Anderson is a geomorphologist who has studied the processes responsible for shaping many landscapes. These include several tectonically active mountain ranges, from the Himalayas to Alaska. He has been involved deeply in the development of methods to extract timing from landscapes, focusing on the use of cosmogenic radionuclides, and consistently employs numerical models in his work.

It is also the premise for deeper understanding of the formation and evolution of the Yardang landform, and the relationship between the Yardang and environment. As a type of erosional landforms, the age of the Yardang landform always remains as a puzzle to researchers, and become a bottleneck in the study. In this article, the authors made a review of the methods for dating Yardang landform.

Then, we made a testing of the methods by applying some of them to date the Yardang landform in the Dunhuang Yardang National Geo-park. Our results suggested that the Yardang landform was formed in a period not later than 10kaBP and not earlier than 39 kaBP.

Luminescence dating is a well-established method of absolute chronology that non-terrestrial geomorphological features such as fault movements, rockfalls.

Darryl E. Granger, Multiple cosmogenic nuclides with different decay rates can be used to date exposure and burial of rocks over the timescales of radioactive decay. Two classes of terrestrial applications are discussed in detail. The first involves the use of 26 Al and 10 Be in rock or sediment that has experienced a complex history of repeated exposure and burial. In these cases, the cosmogenic nuclides can only provide a minimum near-surface age.

Examples include sediment from beneath desert sand dunes, and rocks from beneath cold-based glaciers. The second class of application uses 26 Al and 10 Be to date discrete burial events, in cases where sediment has experienced a simple history of exposure followed by rapid burial. Examples include cave sediments, alluvial deposits, and sediment buried beneath glacial till. Finally, the half-lives of 26 Al and 10 Be are discussed, with special attention given to discrepant estimates of the 10 Be half-life.

It is shown that geologic data are consistent with either half-life estimate of 1.

OPTICAL DATING: History and Theory of the Method and its Application to Research in Geomorphology, Quaternary Geology, and Archaeology. Olav Lian.

Tectonic geomorphology is the study of the interplay between tectonic and surface processes that shape the landscape in regions of active deformation. Recent advances in the quantification of rates, physical basis of tectonic and surface processes have rejuvenated the field of tectonic geomorphology. Modern tectonic geomorphology is an exciting and highly integrative field, which utilizes techniques and data derived from studies of geomorphology, seismology, paleoseismology, geochronology, structural geology, geodesy, and Quaternary climate change.

This module will provide the basis to understand this active research field. Please note that module leaders are reviewing the module teaching and assessment methods for Semester 2 modules, in light of the Covid restrictions. There may also be a few further changes to Semester 1 modules. Final information will be available by the end of August in for Semester 1 modules and the end of October for Semester 2 modules.

They will also prepare for the examination. In accordance with University Terms and Conditions, the University makes all reasonable efforts to deliver the modules as described. Modules may be amended on an annual basis to take account of changing staff expertise, developments in the discipline, the requirements of external bodies and partners, and student feedback.

This paper proposes a review of the use of lichenometry in Iceland since , using different techniques to solve the chronology of geomorphic processes. Based on the results of over 35 published studies, lichenometry has been widely applied in Iceland, proposing numerical ages absolute dating and relative ages relative dating of different surfaces. Increasing awareness of methodological limitations of the technique, together with more sophisticated data processing, has led some authors to claim that lichenometric ‘ages’ are robust and reliable.

However, the different measurement techniques used make it difficult to compare regions or studies in the same area. These problems are exacerbated in Iceland by rapid environmental changes across short distances and more generally by lichen species mis-identification in the field.

The review by Mellars 1 provides an archaeological perspective on some of the latest developments in radiocarbon dating of bone.

However, his presentation, calibration and interpretation of radiocarbon ages are misleading in some cases, and important technical advances in the pretreatment of other sample types that have increased dating accuracy have been overlooked. These considerations may undermine the conclusions drawn about past human dispersals. As Mellars points out 1 , ultrafiltration of bone samples can yield final age determinations that are significantly different from ages derived by traditional methods 1 , 2.

The latest results from ultrafiltration show that the ages originally reported from archaeological contexts should be considered as only minimum estimates. Mellars, personal communication.
