Sedimentary sequences hold the singular advantage that they contain a vertically stacked and relatively undeformed record of erosion, sedimentation, and climatic-tectonic environments and, therefore, obviate many of the difficulties inherent in unraveling complex structural overprints. The geochemical and isotopically studies of sedimentary rocks and minerals therein form a vital approach to tectonic and environmental reconstructions. Latest decades have witnessed significant progress in geochemistry and isotopes of sedimentary rocks and minerals and their applications to fundamental geological issues. For example, advances in dating on calcite using U-Pb isotopic system and dating on illite using K-Ar isotopic system provide additional methods to define the ages of sedimentation/strata besides the conventional paleontological method; documentation of U-Pb-Lu-Hf isotope systematics of detrital zircons from siliciclastic rocks makes it possible to examine the nature of major crustal growth events, both regional and global; work on the geochemistry of limestones deposited in various plate tectonic settings permits the development of proxies for the discrimination of depositional regimes. Therefore, a collection of works regarding this topic is timely and essential to exchange new ideas in the international community and provoke and promote studies in this field.
In this Research Topic, we would like to focus on the recent advances in sedimentary geochemistry and isotopes at whole-rock and/or single mineral scale and their applications to tectonic and environmental reconstructions. Besides, this topic would like to collect provocative ideas regarding the methodology and give summaries of its recent development. Importantly, this Research Topic would like to present new datasets or summaries on the geochemistry and isotopes of specific sedimentary rock or mineral on a global scale or a key regime. Moreover, this Research Topic would like to publish practice examples on a regional scale that can be tracked and referred to by researchers in the same field.
The potential contributors for this Research Topic are suggested to address the following several themes and the preferred manuscripts include Original Research and Review articles.
1. Sedimentary geochemistry and isotopes and their applications to unraveling the evolution of some important tectonic regimes, such as Tethyan Realm, Central Asian Orogenic Belt, etc.
2. Sedimentary geochemistry and isotopes and their applications to revealing the paleoenvironmental characteristics in some critical periods of the geological history.
3. New ideas or reviews on the methodology regarding sedimentary geochemistry and isotopes as well as their applications to geological issues.
4. Geochemistry and isotopes of specific sedimentary rock or mineral on a global scale or on an important regime.
