"This textbook is a complete rewrite, and expansion of Hugh Rollinson's highly successful 1993 book Using Geochemical Data: Evaluation, Presentation, Interpretation. Rollinson and Pease's new book covers the explosion in geochemical thinking over the past three decades, as new instruments and techniques have come online. It provides a comprehensive overview of how modern geochemical data are used in the understanding of geological and petrological processes. It covers major element, trace element, and radiogenic and stable isotope geochemistry. It explains the potential of many geochemical techniques, provides examples of their application, and emphasizes how to interpret the resulting data. Additional topics covered include the critical statistical analysis of geochemical data, current geochemical techniques, effective display of geochemical data, and the application of data in problem solving and identifying petrogenetic processes within a geological context. It will be invaluable for all graduate students, researchers, and professionals using geochemical techniques"--

This book presents general problems in geoarchaeology, and discusses geophysical solutions, X-ray fluorescence spectrometry applications, X-ray and isotope analyses and GIS technologies. It also examines practical reconstructions of technological processes used in ancient time, and investigates the use of minerals and rocks by ancient societies in the territories of modern Russia, Ukraine, Turkmenistan, and Tajikistan, as well as the characteristics of ores, metallurgical slags and data on the composition and impurities of archaeological metals. Intended for archaeologists, historians, museum workers and geologists studying noble metals and copper, the book is also a useful resource for students, graduate students, experts and anyone interested in the use of various minerals at different stages of humanity’s development.

This book provides two state-of-the-art quantitative techniques to determine ultra-trace rare earth elements (REEs) in natural carbonates using solution nebulization-inductively coupled plasma mass spectrometry (SN-ICPMS) and laser ablation-inductively coupled plasma mass spectrometry (LA-ICPMS) with respective applications were presented in this dissertation. These techniques were applied to natural carbonates, including corals and stalagmites, to understand volcano eruptions and the impacts on modern biosystem and paleoclimate regimes. In the first SN-ICPMS protocol, direct measurements for femtogram quantity carbonate samples without chemical separation steps can offer accurate and high-precision analysis (±1.9-6.5%, 2σ) with a high sample throughput of 8-10 samples/hr routinely. Application to modern Porites corals collected from South China Sea region, the anomalies of REE contents and Al/Ca ratios associated with micro-domain images, register modern coral reefs could be exacerbated by volcanic eruptions. In the second protocol, a high-sensitivity quantitative open-cell LA-ICPMS technique has been established to allow direct sampling on stalagmite surface in the atmospheric air. This technique improved limits of detection down to sub-ng/g range and promises analyses of carbonate REE profiles at the single digit parts-per-billion (ppb) levels. Application to a 15-cm stalagmite collected from East Timor reveals two peaks of REE contents by at least one order of magnitude, possibly due to volcanic ash preserved in stalagmite. Both improved SN-ICPMS and LA-ICPMS techniques highlight the high-sensitivity and high-temporal-resolution carbonate REE analyses for corals and stalagmites, with great potential to other natural carbonates such as travertine, tufa, and flowstone, benefit our understanding of paleoclimatic and paleoenvironmental dynamics.

This book focuses on geochemical behavior and ancient records of the specific biomarker levoglucosan in Tibetan glaciers, Based on samples from the Zangsegangri (ZSGR) ice cores obtained from the central Tibetan Plateau, it presents annually resolved levoglucosan records and fire changes over the past 430 years. It also discusses the interaction between fire, climate change, and human activities. This is the first effort to reconstruct annual resolution fire records in Tibetan ice, providing crucial information and substantially improved analytical methods toward a better understanding of past fire changes.
