<p><b>Chemostratigraphy Across Major Chronological Boundaries</b> <p>Chemostratigraphy is the study of the chemical characteristics of different rock layers. Decoding this geochemical record across chronostratigraphic boundaries can provide insights into geological history, past climates, and sedimentary processes. <i>Chemostratigraphy Across Major Chronological Boundaries</i> presents state-of-the-art applications of chemostratigraphic methods and demonstrates how chemical signatures can decipher past environmental conditions. <p>Volume highlights include: <ul> <li>Presents a global perspective on chronostratigraphic boundaries</li> <li>Describes how different proxies can reveal distinct elemental and isotopic events in the geologic past</li> <li>Examines the Archaean-Paleoproterozoic, Proterozoic-Paleozoic, Paleozoic-Mesozoic, and Mesozoic-Cenozoic boundaries</li> <li>Explores cause-and-effect through major, trace, PGE, and REE elemental, stable, and radiogenic isotopes</li> <li>Offers solutions to persistent chemostratigraphic problems on a micro to global scale</li> </ul> <p>Geared toward academic and research geoscientists, particularly in the fields of sedimentary petrology, stratigraphy, isotope geology, geochemistry, petroleum geology, atmospheric science, oceanography, climate change??and environmental science,<i> Chemostratigraphy Across Major Chronological Boundaries</i> offers invaluable insights into environmental evolution and climatic change.
