Special Issue Information
Fluctuations in the relative sea level control the rate of the sediment supply, primary mineralogical composition, pore water chemistry, sediment budget and architecture of depositional systems. The rate of sedimentation is controlled by hinterland geology, climatic conditions, changes in the relative sea level and the energy of the sediment distributary systems.
Sandstones consist of detrital grains such as quartz, feldspars and rock fragments, derived from the weathering of the source area (provenance). Different hydraulic and fluid flow regimes produce distinct sets of sedimentary structures, facies and facies associations. Carbonate sediments, to a large extent, are produced in situ as precipitates, skeletons and chalks within the depositional setting.
Studying facies and facies associations in siliciclastic rocks to infer depositional environments can be achieved by describing logs, seismic sections, outcrops and cores. Whereas in carbonate rocks, it is not uncommon that seismic and logs are not of any significant help and there are often no visible components, trace fossils and sedimentary structures; therefore, the task of deciphering depositional environments requires a detailed petrographic assessment of facies and rock strata.
Shelf settings consist of diversity of depositional environments, which produce the largest volume of modern carbonates and contain the most significant volume of ancient carbonate sediments dominating the geologic record. Often, the lateral variations in facies and sedimentary geometries along a carbonate shelf (from proximal to distal areas) are characterized by predictable changes in the rock characteristics; however, in mixed carbonate-evaporite and carbonate–siliciclastic successions, a significant complexity is facing the efforts of unraveling the physical, chemical and biological controls that determines the characteristics and distribution of the sedimentary successions.
Research articles within the scope of this Special Issue (SI) sheds light on the paleoclimatic and palaeoceanographic evolution of ancient earth conditions and aids the exploration of natural resources, including water and hydrocarbons.
In this Special Issue (SI), we seek contributions on modern and ancient depositional environments to unravel the complexity of the interpretations of the depositional processes in siliciclastic, carbonate and mixed siliciclastic–carbonate systems. Contributions on shallow burial post-depositional processes (diagenetic alterations), which further complicate the interpretation of the primary depositional textures, are also welcome.
Dear Colleagues,
I invite you to contribute to a Special Issue (SI) entitled Marine Geologic Features and Processes in Siliciclastic, Carbonate and Mixed Siliciclastic–Carbonate Systems. The SI will be addressing the sedimentology, facies, sediment distribution and depositional processes along siliciclastic, carbonate and mixed siliciclastic–carbonate systems. Integrating, field, lab, geological, geophysical and geochemical data would be welcomed.
The SI will be accepting contributions from the geological data of different scales (from thin sections to seismic lines). Contributions on shallow burial post-depositional processes (diagenetic alterations) linked to facies, stratigraphy and primary depositional textures are also welcome.
Prof. Dr. Howri Mansurbeg

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 100 words) can be sent to the Editorial Office for announcement on this website.
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-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly 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 2600 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.
