Geochemistry of low‐temperature dolomite formation in coastal and continental saline to sabkha‐like environments

The Depositional Record, Volume 12, Issue 4, September 2026.
This study compares primary dolomite precipitation in modern and ancient environments, varying from coastal to transitional to continental saline environments. The microbially mediated dolomites are characterised by high Sr concentrations. Here, various geochemical proxies are studied and compared to previous findings.

Sedimentary facies and stacking patterns of fluvio‐deltaic and ‐estuarine deposits from the Palaeoarchean Moodies Group in the Stolzburg Syncline (Barberton Greenstone Belt, South Africa)

The Depositional Record, Volume 12, Issue 4, September 2026.
Drillcore BASE‐5B from the Stolzburg Syncline, Barberton Greenstone Belt, reveals a coarsening‐upward, river‐dominated fluvio‐deltaic succession transitioning upward to a fining‐upward, tide‐dominated‐estuarine succession. Abstract Investigating fluvio‐marine depositional environments from early geological times is of great importance, as they provide ...

Flexural bulges and foredeep basins: Dynamic tectonic control on shifting depocentres and condensed facies, Upper Cretaceous (Santonian), Western Canada Foreland Basin

The Depositional Record, Volume 12, Issue 4, September 2026.
Allostratigraphically defined mudstone packages show marked along‐strike thickness variation, interpreted to be related to shifting thrust activity in the orogen; loading cycles lasted about 750 kyr. Close to the orogen, the forebulge is mantled by shelly sandstone whereas far from the orogen, the forebulge is typified by organic‐rich mudstone ...

Zircon ages delimit the provenance of a sand extrudite from the Botucatu Formation in the Paraná volcanic province, Iraí, Brazil

Anais da Academia Brasileira de Ciências, 2015
Ion microprobe age determinations of 102 detrital zircon crystals from a sand extrudite, Cretaceous Paraná volcanic province, set limits on the origin of the numerous sand layers present in this major flood basalt province.

Detrital zircon ages, Lu‐Hf isotopes of zircon grains, Sr‐Nd isotopes on whole rock and geochemistry of Campanian turbidites in the Eastern Pontides (NE Türkiye): A provenance assessment and Gondwana records

The Depositional Record, Volume 12, Issue 4, September 2026.
These findings confirm that the Campanian‐aged Bozbent Member turbiditic sequence in the Eastern Pontides was deposited in an extensional fore‐arc basin and therefore exhibits the petrographic and geochemical characteristics of passive margin sandstones.

Pyrolytic data verification in potential assessment and catagenetic transformation of the Proterozoic low-carbon formations of eastern Siberia

Georesursy
The ancient Precambrian formations of Eastern Siberia include oil and gas source rock (SR) interlayers, but in most cases, they can’t be classified as high-carbon ones, because the actual organic carbon content in these strata is low and rarely exceeds ...
