A 30 m long sedimentary succession at the bottom of the Belize Blue Hole represents terrestrial cenote (12.5–7.2 ka BP), restricted marine swamp (7.2–5.7 ka BP) and fully marine lagoonal phases (5.7–0 ka BP) on Lighthouse Reef carbonate platform. Post‐glacial and Holocene sea‐level rise largely controlled the sedimentological, faunal and floral changes

Guide to the geology of Bradgate Park and Swithland Wood, Charnwood Forest [PDF]
Charnwood Forest is one of the few parts of England where there are exposures of ‘basement’ rocks dating back to Precambrian time. Its locally rugged topography is caused by these highly resistant rocks protruding as craggy knolls through a surrounding ...

The Bisperode section is one of the most expanded and complete sections with shallow‐marine Oxfordian strata in the LSB. This study provides a reference record for shallow‐marine settings and allows for the correlation of the strata from the LSB with Oxfordian deposits distributed elsewhere in the world.

Sources and mechanisms for the enrichment of highly reactive iron in euxinic Black Sea sediments [PDF]
The deep basinal euxinic sediments of the Black Sea are enriched in iron that is highly susceptible to sulfidization compared to oxic/suboxic continental margin sediments in the Black Sea and oxic/dysoxic continental margin and deep-sea sediments ...

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.

Anomalously cool clumped isotope temperatures in tropical lagoon carbonates
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.
