Biostratigraphic correlation of the western and eastern margins of the Labrador-Baffin Seaway and implications for the regional geology [PDF]

Geological Survey of Denmark and Greenland Bulletin, 2016
New analyses of the palynological assemblages in 13 offshore wells on the Canadian margin and six on the West Greenland Margin, in conjunction with onshore data, have led to a new biostratigraphic framework for the Cretaceous–Cenozoic strata of the ...

Evidence From Microscopy and U–Pb Geochronology as a Clue to the Influence of the Cretaceous Magmatism in the Diagenesis of Pre‐Salt Carbonate Reservoirs in the Santos Basin (Brazil)

Geological Journal, Volume 61, Issue 7, Page 1976-2001, July 2026.
Carbonates from Santos Basin revealed U–Pb ages correlated with basalt ages (A), suggesting that they were formed during magmatic events. These events placed hot CO2 in the reservoir, which, when mixed with carbonate‐rich cold water (B), led to thermal convection, enabling the formation of the U contained in the carbonates.

An overview on Callovian-Cenomanian intracratonic basins of Northeast Brazil: Onshore stratygraphic record of the opening of the southern Atlantic

Geologica Acta, 2003
A number of small Callovian-Albian sedimentary basins occur in the NE-trending Araripe-Potiguar topographic lowlying area. These basins developed in a fairly narrow zone of Precambrian supracrustal rocks from the Middle Jurassic onwards, as a consequence
