Marcasite at the Permian‐Triassic Transition
Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

The variations in assemblages of calcareous nannofossils are tracked in the Dakhla and Tarawan Formations exposed at Gebel Nezzazat (central Sinai, Egypt). Five calcareous nannofossil biozones, namely NP2/3, NP4, NP5, NP6, and NP7/8 are identified.

Investigating bio-events and time expansion of Calcareous nannofossils in the upper part of the Gurpi Formation and lower part of the Pabdeh Formation, northwestern Shiraz [PDF]
In this study, calcareous nannofossils are investigated in the upper part of the Gurpi Formation and lower part of the Pabdeh Formation at the Par-e Nobar section located in the northwest of Shiraz. The thickness of the studied section is about 41 m. The

The calcareous nannofossil Prinsiosphaera achieved rock-forming abundances in the latest Triassic of western Tethys: consequences for the δ13C of bulk carbonate [PDF]
The onset of pelagic biomineralization was a milestone in the history of the long-term inorganic carbon cycle: as soon as calcareous nannofossils became major limestone producers, the pH and supersaturation state of the global ocean were stabilized (the ...
