The effect of meteoric water on the very fine crystalline dolomite reservoir in the shallow burial zone: A case study of the Ma55 submember of Majiagou Formation in Ordos Basin

Frontiers in Energy Research, 2023
The meteoric water has obviously changed the physical properties of dolostone reservoirs in the vertical vadose zone and the horizontal phreatic zone, but its influence on the dolostone reservoirs in the shallow burial zone beneath the phreatic surface ...

Transient Porosity During Fluid‐Mineral Interaction, Part 2: Reconstruction Using Generative AI

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 6, June 2026.
Abstract Quantifying fluid–rock interactions within the lithosphere is vital for both geological processes and applications such as CO2 ${\text{CO}}_{2}$ storage and geothermal energy development. Mineral replacement reactions generate transient pore networks that enhance fluid flow, yet many pores become isolated once reactions are completed, reducing

A tale of two microbialites: Stromatolites and microbially induced sedimentary structures

Sedimentology, Volume 73, Issue 4, Page 849-863, June 2026.
ABSTRACT Microbialites are biosedimentary structures built by microbial mats. Five microbialite groups are distinguished: stromatolites, thrombolites, dendrolites, leiloites and microbially induced sedimentary structures (MISS). This contribution discusses the two most abundant microbialite groups in marine settings, stromatolites and MISS.

An Ecological Perspective on Dolomite Formation in Great Salt Lake, Utah

Frontiers in Earth Science, 2020
Protodolomite was detected in sediments from Great Salt Lake (GSL), Utah, United States, that have no history of elevated temperature or pressure, conditions that are thought to promote dolomitization of sedimentary carbonates. Protodolomite was abundant

Barium Isotopes Indicate Spatiotemporal Heterogeneity of Marine Primary Productivity During the Toarcian Oceanic Anoxic Event

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract The Toarcian Oceanic Anoxic Event (T‐OAE, ∼183 Ma) was characterized by globally enhanced organic‐carbon burial and a negative carbon‐isotope excursion (N‐CIE). However, the role of marine productivity at this time, and its spatiotemporal variability, is unclear.

Deposition, diagenesis, and reservoir development of the Cretaceous Lidam formation, SE Sirt Basin, Libya. [PDF]

, 2007
This study concentrates on the deposition, diagenesis and reservoir characteristics of the Upper Cretaceous (Cenomanian) Lidam Formation. Core, petrography and geochemical data were studied from five wells (P3-97, N6-97, R1-97， 3V1-59E, and 3V3-59E) in ...

Magnetotelluric Exploration of Zn Pb Mineralization in Stonepark, Irish Midlands

Geophysical Prospecting, Volume 74, Issue 4, May 2026.
ABSTRACT To meet the increasing demand for raw materials and to foster the energy transition, advances in exploration techniques are required that extend capabilities to deeper and/or more densely populated areas while having a low environmental and societal impact.

Hydrothermal dolomitization of basinal deposits controlled by a synsedimentary fault system in Triassic extensional setting, Hungary

, 2016
Dolomitization of relatively thick carbonate successions occurs via an effective fluid circulation mechanism, since the replacement process requires a large amount of Mg-rich fluid interacting with the CaCO3 precursor.

Contrasting Rare Earth Element Signatures Between Stromatolitic Carbonates and Lagoon Waters at Shark Bay, Western Australia: Implications for Paleo‐Environmental Reconstructions of Microbial Habitats

Geobiology, Volume 24, Issue 3, May/June 2026.
ABSTRACT Rare earth elements and yttrium (REY) signatures in stromatolitic carbonates have emerged as powerful geochemical proxies for reconstructing paleo‐depositional environments of microbial habitats. The applicability of such a proxy relies on the assumption that REY substitutes for calcium into crystal lattices, directly reflecting the ...
