Reconstitutions of Paleoenvironments and Paleoclimates using Stable Isotope Geochemistry

Dear Colleagues,

The aim of this Special Issue is to collect high quality, original and innovative research papers devoted to the reconstruction of paleoenvironments and paleoclimates based on geochemical proxies. Contributors are invited to submit studies that refer to data and interpretations having a high capacity for improving our knowledge of past-Earth climates at the global significance level. Those contributions will be especially appreciated as they will relate to their impact on ore deposits and water resources, as well as on temporal and spatial changes in either marine or terrestrial biomass and biodiversity. Case studies leading to scientific outcomes of regional significance are not encouraged, except if they involve sedimentary deposits bearing an exceptionally well-preserved faunal or floral content. Emerging techniques (imaging, spectroscopy, spectrometry) and methods (modelling, proxies, experimentation) that allow significant progress to be achieved in paleoclimatology are also warmly welcomed.

In the oceanic domain will be concerned the reconstruction of sea surface temperatures (SST) and salinity (SSS) either with depth or latitude, their seasonal variations, changes in seawater pH, variations in the d18O of seawater related to ice volume effects, and evolution of the oceanic circulation patterns depending on the greenhouse versus icehouse climate state of the Earth.

In the terrestrial domain (continents, islands) will be concerned the reconstruction of mean annual temperatures (MAT), mean annual precipitations (MAP), their long-term (104 to 106 years) and short-term (100 to 103 years) variations, prevailing winds and relative humidity. In relation to the dynamics of climate change, the sedimentary record of atmospheric chemistry (O2, CO2, CH4, SO2) will be given particular attention through the study of redox-sensitive elements (C, Cr, Cu, Fe, I, Mo, Mn, Re, S, Se, U, V, Zn), stable isotope compositions of fossil plant remain, and fluid inclusions trapped in evaporites.

Research topics will be especially considered for publication according to the keywords presented at the bottom of this page. Authors are invited to send to the Guest Editor a title, list of authors and abstract of the manuscript they would like to submit to this Special Issue of Geosciences.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Geosciences is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
