Call for papers for the special issue: Calcium Isotope Geochemistry: Past Lessons and Future Directions
• 大类 : 地学 - 2区
• 小类 : 地球化学与地球物理 - 2区
Calcium isotopes have been utilized as geochemical tools since the early 1970s, increasing in popularity and scope since the mid- to late 1990s. Research conducted over the past thirty years has revealed a range of Ca isotope applications, as well as a series of interesting and fundamental problems that have yet to be resolved. For such a chemically-simple system, in comparison to redox-active elements for instance, the level of complexity is somewhat surprising. In addition, Ca isotopes can present an analytical barrier for new users; for instance, the most accurate analytical technique remains thermal ionization mass spectrometry, which requires an isotopic double spike (the preparation and calibration of which can intimidate potential users). Thus, the discussion of analytical and methodological issues, which some systems grow out of to some extent, remain relevant to Ca isotopes.
This Ca isotope-focused special issue will present both invited and general-call papers (all submissions are welcome). The issue will be organized around the following topical areas, which each of the six invited manuscripts will focus on:
(1) New Developments and Old Issues in Ca Isotope Analysis
(2) Elucidating Modern Geochemical Cycles at Local, Regional and Global Scales using Ca Isotopes
(3) Ca Isotopes in Deep Time: Potential and Limitations
(4) Calcium Isotopes in High-Temperature and Cosmochemical Systems
(5) Numerical Approaches to Interpreting Ca Isotope Dynamics in Experimental and Natural Systems
(6) New Frontiers in Ca Isotope Geochemistry
The general purpose of the special issue is to identify the research areas/questions that most benefit from the application of Ca isotopes in these topical areas, to evaluate critically outstanding questions in these topical areas, and to describe future directions that can move the field forward.
