Abstract: This study focused on developing luminescence dating procedures for feldspar, and the application of the luminescence dating technique to fluvial terraces of Anjihai River in the northern piedmont of Tian Shan range, China, to evaluate the deformation rate of the Anjihai anticline in the late Quaternary. To develop luminescence dating methods, a low temperature multi-elevated-temperature post-infrared infrared stimulated luminescence (MET-pIRIR) protocol has been proposed for measuring the Holocene samples using K-feldspar. Progressively increasing IR stimulation temperatures from 50 to 170 C in step of 30C were used in the protocol. The residual doses for the MET-pIRIR signals were generally less than 1 Gy. This protocol was further simplified to a three-step pIRIR method, with three stimulation temperatures of 110, 140 and 170C. It has been shown that these new pIRIR methods can be applied successfully to aeolian samples within the Holocene. A high temperature MET-pIRIR dating protocol was initially applied to polymineral fine grains (4-11 μm), recovered from Chinese loess samples collected at Luochuan that accumulated within the last glacial-interglacial period. The MET-pIRIR ages for fine grains were compared with the coarse grain (63-90 μm) K-feldspar MET-pIRIR ages and the coarse grain quartz OSL ages, and the stratigraphic age controls. The results show that the MET-pIRIR protocol can be applied to fine grains from these loess samples without fading correction. A plateau test, termed the De (T, t) plot, was proposed as a self-diagnosing tool for the pIRIR dating protocols. The pattern of the De (T, t) plot was shown to be affected by non-bleachable signal, partial bleaching and anomalous fading effects. The achievement of a plateau in the De (T, t) plot indicates that the non-fading signal has been achieved, and the effects of non-bleachable dose and partial bleaching are negligible. The De (T, t) test was successfully applied to different pIRIR protocols. A series of loess and fluvial sand samples were collected from the north piedmont of Tian Shan range to determine appropriate dating procedures for samples in this area. Luminescence properties of quartz and K-feldspar grains extracted from these samples were investigated. The extent of bleaching for the samples and the reliability of the measured ages were assessed based on equivalent dose distribution and age comparison between chronometers. Optimized dating procedures for samples in north Tian Shan have been proposed. K-feldspar MET-pIRIR dating is recommended for the loess samples, while single aliquot quartz OSL dating is suggested for the fluvial sand samples, after consideration of signal brightness and the extent of signal resetting. The dating procedures proposed above were applied to the deformed fluvial terraces of Anjihai River in the north flank of Tian Shan. Combined with topographic measurements, the deformation rate of the Anjihai anticline was calculated. The average shortening rates of the Anjihai anticline since 3.6 0.1, 9.0 0.6 and 53.3 2.2 ka were calculated to be 1.4 0.3, 1.2 0.3 and 0.5 0.1 mm/a, respectively. It suggests that the northern Tian Shan region was tectonically active during the late Quaternary, especially in the Holocene.

Book excerpt: Luminescence dating is now widely applied by scientists working in Quaternary geology and archaeology to obtain ages for events as diverse as past earthquakes, desertification and cave occupation sites. Using quartz or feldspar minerals found in almost ubiquitous sand and finer sediments, luminescence can provide ages from over 500,000 years ago to modern.Written by some of the foremost experts in luminescence dating from around the world, this book takes a new approach. It explains what luminescence can and can't do, what and where to sample, types of measurements available and how to interpret and analyse ages once they are measured. It is accordingly for scientists who require luminescence ages for their research rather than those scientists developing the luminescence technique or making their own luminescence measurements. The background to the technique is explained in simple terms so that the range of potential applications, limits and issues can be understood. The book helps scientists plan where and what to sample to optimise the successful application of luminescence and stemming from that the chronologies that can be constructed. The Handbook sets out the challenges and limitations when applying luminescence dating in different environmental and archaeological settings and gives practical advice on how issues might be avoided in sampling, or mitigated by requesting different laboratory measurement approaches or analysis. Guidance is provided on how luminescence ages can be interpreted and published as well as how they can be used within chronological frameworks. With luminescence dating continuing to develop, information on more experimental approaches is given which may help expand the range of chronological challenges to which luminescence dating can be routinely applied.

It has been reactivated as a result of the Cenozoic India-Eurasia collision. Dating of the late Cenozoic tectonic deformation of Tian Shan and its piedmonts is important for understanding the mountain building as well as evaluating seismic hazards in the region. This study is focused on the applications of optical dating to the late Quaternary uplift and thrust activity along Manas River, in the northern piedmont of the Tian Shan, China. The sediments on river terraces were dated with optical dating. The elevations were measured with the kinematic global position system (GPS). The results suggest that two phases can be identified according to the significantly different river incision rates. One phase was from 20 ka to 4.8 ka, with a much slower incision rate of 2.2 0.6 mm/yr. The other phase was from 4.8 ka to present, with a faster incision rate of 13.5 0.6 mm/yr. The accelerated incision rate of Manas River was mainly attributed to the tectonic forces, suggesting that the tectonic uplift was significantly intensified since 4.8 ka in the northern piedmont of Tian Shan. The study region has suffered from multiple thrust activities during the late Quaternary, which led to the intensive deformations of the river terraces. By studying the deformed terraces, I evaluated the timing of the past thrust activities as well as the vertical slip rate of the thrust faults. The results demonstrated that the thrust activity intensified during the late Holocene, as manifested by the more frequent thrust activities and higher vertical slip rates. Both quartz and potassium feldspar can be as dosimeters for optical dating of sediments. However, quartz OSL is sometimes seriously impeded with problems such as very dim signals and insufficient bleaching problems. K-feldspar has attractive advantages over quartz, despite of problem of anomalous fading. K-feldspar was explored in this study, by investigating the relationship between the infrared stimulated luminescence (IRSL) and blue light stimulated luminescence (BLSL) signals. For IRSL and BLSL at 60 C, it was suggested that most of the IRSL could be bleached by blue light (BL), while the BLSL could only be partially bleached by infrared (IR) stimulation. Besides, the fast and medium components of BLSL were mainly associated with the IRSL. If IR stimulation temperature was raised from 60 to 200 C, at least two portions of the IRSL signals at 200 C were observed. One portion could be bleached by BL at 60 C and the other portion was hardly bleached by BL at 60 C. Dating of K-feldspar from the various signals provided cross-checking for the reliability of quartz OSL for dating sedimentary samples.

Available in PDF, EPUB and Kindle. Book excerpt: Trapped charge dating is a commonly used chronological tool in Earth Sciences and Archaeology. The two principle methods are luminescence dating and electron spin resonance. Both are based on stored energy produced by the absorption of natural radioactivity in common minerals such as quartz and feldspars, and in some biological materials such as tooth enamel. Methodological developments in the last 20 years have substantially increased the accuracy and precision of these methods. This compilation offers a taste of the recent research into both method and applications.

This book was released on 2020-07-09 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optically stimulated luminescence (OSL) dating has proven to be extremely useful for establishing the Late Quaternary chronological framework in many areas of the Brazilian territory. In this region dominated by tropical climate, OSL dating can be more extensively applied than radiocarbon dating due to the generally low potential for the preservation of organic matter in sedimentary samples. This problem is especially critical in areas of the Amazonian lowlands, because of the hot climate and high precipitation rates. The abundance of quartz grains deposited in fluvial and aeolian environments over this region favours OSL dating. More than 20 years of continuous and collaborative work has resulted in the creation of an extensive OSL age database for Late Quaternary sedimentary deposits in the Amazonian lowlands. This effort has contributed to improving the paleoenvironmental and paleoclimatic reconstructions of this region within this period. This book discusses the state of art of OSL dating of Late Quaternary deposits in the Amazonian lowlands, focusing on providing an introduction to dating principles using OSL, and defining the application of OSL techniques as a dating method. It also offers a statistical study and calculation of equivalent dose and annual dose rates, details the sampling and experimental apparatus, and considers the difficulties and adaptation techniques in dating Late Quaternary strata in the Amazonian lowlands.
