Special Issue Information

Dear Colleagues,

On behalf of Minerals, we are pleased to announce the Special Issue "Carbonate Petrology and Geochemistry" and we would like to invite you to contribute to this Special Issue that focuses on the carbonates (rocks and sediments) deposited in continental and marine environments, irrespective of their age. Carbonate rocks and sediments emerge in response to mechanisms forced primarily by high environmental CO2 contents. Therefore, research on petrological and geochemical carbonate topics is critical for understanding the global carbonate cycle, as carbonate minerals comprise the largest reservoir of carbon in the Earth’s lithosphere.

Remarkable advances have recently been made in understanding the petrology and geochemistry of carbonates, mainly considering environmental changes and their ecological impact. Furthermore, in recent decades, analytical techniques have also advanced and offer a more complete vision to scientists in mineralogy, petrology and geochemistry, making data available with a superlative analytical and spatial resolution.

The purpose of this Special Issue is to collect original research studies that can shed new light on the advances in stratigraphy, sedimentology, petrology, geochemistry, (paleo)climate, (pale)oceanography and hydrogeology of carbonate rocks and/or sediments. Contributions may embrace a broad spectrum of topics, because this Special Issue aims to show a comprehensive and up-to-date perspective of past and recent carbonates, whilst taking into account the fact that carbonate research is more focused on the assessment of processes and genetic relationships between textures and mineralogical, and geochemical compositions. Contributions can either be review papers related to special topics or very specialized research studies, offering new perspectives on specific aspects of recent or past carbonates.

Topics of interest include, but are not limited to, the following: (1) the architecture and interpretation of carbonate outcrops; (2) the diagenetic and geochemical controls regarding carbonate deposition; (3) carbonate rocks or sediments as an archive of ancient/recent (paleo)-environmental changes; (4) role of carbonates in (pale)oceanography and the global carbon cycle; (5) recognition of primary versus diagenetic overprint in carbonates; (6) carbonate significance as a source and reservoir rocks.

We thank you and look forward to receiving your contributions.

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. Minerals 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 2400 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.

Geochemical proxies are a reliable tool in deciphering the paleoenvironment and diagenetic alteration in carbonate rock units. The Lower Cretaceous Yamama Formation (LCYF) is an important carbonate unit of the Saudi Arabia region which has been studied in detail to evaluate the paleoenvironment and diagenetic alteration through geochemical studies. This study presents new data on petrography, stable isotopes, and trace and rare-earth elements to enhance our understanding on paleoenvironments, redox conditions, and paleosalinity during the deposition of these carbonate units. Field studies show that the formation is composed of thick-to-thin-bedded limestone. Petrographic studies show that the formation is mostly composed of mudstone, wackestone, packstone, and grainstone facies. The stable isotopic values of carbon (δ13C V-PDB = +0.58‰ to +2.23‰) and oxygen (δ18O V-PDB = −6.38‰ to −4.48‰) are directly within the range of marine signatures. CaCO3’s dominance over SiO2 and Al2O3 indicates minimal detrital contribution during the LCYF precipitation. The REE pattern suggests coeval marine signatures which include (i) a slight LREE depletion compared to HREEs (av. Nd/YbN = 0.70), (ii) negative Ce anomalies (av. Ce/Ce* = 0.5), and (iii) a positive La anomaly (av. La/La* = 1.70). Micritic limestone has low Hf (bdl to 0.4 µg/g), Sc (bdl to 2.5 µg/g), and Th (bdl to 0.8 µg/g) content, which suggests negligible detrital influence. The Ce content of different facies (Ce = 1u.80 to 12.85 µg/g) suggests that their deposition took place under oxic to dysoxic conditions. However, there is moderate variation during the deposition of MF-I, with higher Ce values as compared to MF-II, MF-III, and MF-IV, which suggests that the deposition of MF-I mostly took place in anoxic to dysoxic conditions.
