Anomalously cool clumped isotope temperatures in tropical lagoon carbonates

open access: yesThe Depositional Record, EarlyView.
Carbonate clumped isotopes were used to reconstruct paleoclimate from lagoon sediments in the central tropical Pacific. Results were anomalously cool compared to modern measurements and other paleoclimate records. This study highlights the important of understanding carbonate facies and depositional environments in interpreting clumped isotope results.

Structural pattern and its control on hydrocarbon accumulations in Wushi Sag, Kuche Depression, Tarim Basin

open access: yesPetroleum Exploration and Development, 2008
Affected by the South Tianshan orogenesis, the faulted structure patterns in the Wushi Sag are very complex. Aimed to find out the basic characteristics of the structures, this article studies many seismic profile sections, the regional geology, the ...

Construction of a Geological Fault Corpus and Named Entity Recognition

open access: yesApplied Sciences
The rapid and effective extraction of fault entities is a fundamental process in constructing a fault knowledge graph. As a key method for recording and preserving fault data, a fault investigation report holds significant potential for extracting ...

Trace elements, rare earth elements and isotopes of poorly preserved fossils from lower Cretaceous carbonates (Eastern Black Sea): Implications for early diagenetic alteration

open access: yesThe Depositional Record, EarlyView.
Analysing Rare Earth Elements (REEs) and other trace elements together with stable isotope data in poorly preserved belemnites can provide valuable insights into early diagenetic pathways, water‐interaction processes, and even potential redox conditions.

Rupture characteristics and seismic assessment of the Qinling northern piedmont fault

open access: yesNatural Hazards Research, 2022
Research on fault rupture characteristics and behaviors, as well as the quantification of activity parameters is an important basis to evaluate the future seismic hazard.

Stratigraphy of diagenesis: Limestone–dolomite cycles in a mid‐ramp setting, Miocene Arcadia Formation, South Florida, USA

open access: yesThe Depositional Record, EarlyView.
The data and interpretations of this study are used to test the proposal by Goldhammer et al. that a ‘stratigraphy of early diagenesis’ is operational in carbonate depositional systems. What this means is that distinct mineralogical and geochemical changes to rock and sediment occur associated with external controls, such as the rise and fall of sea ...

Influence of environment and mineralogy on euendolithic microboring patterns

open access: yesThe Depositional Record, EarlyView.
Field experiments at Little Ambergris Cay reveal that euendolithic microorganisms preferentially bore carbonate substrates based on mineralogy, sea water saturation and trace metal content. Results highlight night‐time dissolution activity and mineralogical preferences, shedding light on the ecological and evolutionary drivers of bioerosion and their ...
