Glen Torridon (GT) is a recessive-trough feature on the northwestern slope of “Mt. Sharp” in Gale crater, Mars with highest Fe-/Mg-phyllosilicates abundances detected by Curiosity rover to date. Understanding origin these clay minerals and their relationship diagenetic processes critical for reconstructing nature habitability past surface subsurface environments crater. We aim constrain distrib...

The Ediacaran Period (ca. 635–541 Ma) witnessed the earliest paleontological evidence for macroscopic animals (i.e., Ediacara biota) and geochemical observations of largest carbon cycle anomaly in Earth history Shuram Excursion, SE). Numerous hypotheses have been proposed origins SE, ranging from primary seawater to syn- or post-depositional diagenesis. Despite intensive theoretical work publis...

The Deccan Trap continental flood basalt eruptions of India occurred c. 67–63 Ma, thus spanning the Cretaceous–Tertiary boundary (65 Ma). Deccan eruptions were coeval with an interval of profound global environmental and climatic changes and widespread extinctions, and this timing has sparked controversy regarding the relative influence of Deccan volcanism upon endCretaceous catastrophic events...

A sediment model has been developed to simulate the Sediment Oxygen Demand (SOD) and sediment nutrient fluxes after a sudden input of Particulate Organic Matter (POM). Compared with previous sediment models, the main model advancements are the use of a continuous function to represent the kinetics of POM diagenesis and inclusion of the biomass content in POM diagenesis. Laboratory experiments a...

Evidencing ancient interspecific associations in the fossil record may be challenging, particularly when bacterial organisms have most likely been degraded during diagenesis. Yet, documenting ancient interspecific associations may provide valuable insights into paleoenvironmental conditions and paleocommunities. Here, we report the multiscale characterization of contemporary and fossilized calc...

The present work focuses on the upper Cretaceous (Cenomanian-early Campanian) carbonate successions in selected wells from northwestern Iraq. These are represented by Gir Bir Turonian), Wajna (late Santonian) and Mushorah (early Formations. succession has affected early burial near-surface, unconformity-related deep diagenesis cementation, neomorphism, dolomitization, dedolomitization, silicifi...

Abstract Palaeozoic stromatoporoids, throughout their 100-million + year history (Middle Ordovician to Late Devonian and rare Carboniferous), are better preserved than originally aragonite molluscs, but less well-preserved low magnesium-calcite brachiopods, bryozoans, trilobites corals. However, the original mineralogy of stromatoporoids remains unresolved, details diagenesis patchy. This study...
