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. At last,we prospect the direction of the yardang formation chronology research.

Reconstruction of the patterns of Pleistocene glaciations in the mountains of Southern Siberia, as well as correlating the sediments within mountains of Central Asia mountain belt and platform areas of Siberia, is not possible without absolute dating of glacial deposits, but these types of continental sediments are very complex to date absolutely. By now there is a wide arsenal of different numeric techniques for age determination of Quaternary sediments Wagner, The application, precision and accuracy of each of them vary considerably Fuchs and Owen, However, within the Russian Altai utilizing most of techniques are highly problematic.
Organic material generally is not presented in ancient glacial sediments. Moreover, glacial sequences are beyond the radiocarbon timescale and geological materials suitable for other radiogenic dating methods are also absent.
The central premises of applications of the in situ cosmogenic dating method for studying specific problems in geomorphology are outlined for simple and.
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.

Caves are important markers of surface evolution, since they are, as a general rule, linked with ancient valley bottoms by their springs. However, caves can only be dated indirectly by means of the sediments they contain. If the sediment is older than common dating methods, one has to use multiple dating approaches in order to get meaningful results. Although it is only a single cave, the information contained within it makes it an important site of the Southern Alps.
This important tectonic line caused dextral strike—slip faulting and differential uplift Fodor et al. In order to reconstruct the valley deepening processes in time, and to quantify uplift activity along the fault, paleoelevation markers are needed. Although horizontality is no proof in itself for a position close to the baselevel, speleogenetic research shows that large subhorizontal caves are most of the time closely related to the baselevel Klimchouk et al.
Caves contain, generally, sediments that are comparatively easy to date with different methods. In this article, we present the methods used and their results, and we interpret the cave’s genesis in relation to activity phases of the Periadriatic fault. They are built of thrust sheets of Triassic sediments carbonates, sandstones, marls and volcanics keratophyre, porphyre and diabase.
The Raduha Massif is an eastern carbonate promontory, consisting of massive and thick-bedded Upper Triassic limestone Fig. Deeply entrenched valleys separate it from other ridges.

This chapter provides researchers with a guide to some of the types of dating techniques that can be used in geomorpological investigations and issues that need to be addressed when using gechronological data, specifically issues relating to accuracy and precision. This chapter also introduces the ‘types’ of dating methods that are commonly used in geomorphological studies.
The book covers cutting edge topics, including the revolutionary cosmogenic nuclide dating methods and modeling, highlights links to other Earth sciences.
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.
An introduction to dating techniques: A guide for geomorphologists
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.

Bob has now studied most parts of landscapes, from the glaciated tips to the coastal toes, with significant attention to sediment transport mechanics, interaction of geophysical and geomorphic processes to shape mountain ranges, evolution of bedrock canyons and glaciated landscapes. He has participated in the development of a new tool kit that employs cosmogenic radionucides to establish timing in the landscape.
He develops numerical models of landscapes that honor both field observations and first principles of conservation; these models in turn have served to hone his field efforts.
