Holocene development of submerged keep‐up patch reefs on Bermuda without acroporids: A model of future reef accretion

open access: yesThe Depositional Record, EarlyView.
Bermuda patch reefs development was primarily controlled by massive coral framework construction, and variation in environmental energy, turbidity and bioerosion. These factors shaped the size, diversity and preservation of the framework, leading to a suppressed, steady vertical accretion.

Stratigraphy and development of the Late Miocene-Early Pleistocene Hawke’s Bay forearc basin [PDF]

open access: yes, 2004
A Late Miocene-Early Pleistocene mixed carbonate-siliciclastic sedimentary succession about 2 500 m thick in the Hawke’s Bay forearc basin is the focus of a basin analysis. The area under investigation covers 3 500 km2 of western and central Hawke’s Bay.

Exploration for volcanogenic sulphide mineralisation at Benglog, north Wales [PDF]

open access: yes, 1983
Exploration for volcanogenic sulphide mineralisation around Benglog is one of three investigations designed to assess the metallogenic potential of the Ordovician Aran Volcanic Group.

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.

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 ...

Late Miocene – Early Pleistocene paleogeography of the onshore central Hawke’s Bay sector of the forearc basin, eastern North Island, New Zealand, and some implications for hydrocarbon prospectivity [PDF]

open access: yes, 2008
The timing of trap formation in relation to the timing of source rock burial and maturation are important considerations in evaluating the hydrocarbon prospectivity of onshore parts of the forearc basin in central Hawke’s Bay.

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 ...

Improving Seismic Fault Recognition with Self-Supervised Pre-Training: A Study of 3D Transformer-Based with Multi-Scale Decoding and Fusion

open access: yesRemote Sensing
Seismic fault interpretation holds great significance in the fields of geophysics and geology. However, conventional methods of seismic fault recognition encounter various issues.
