Changes in Cave Sedimentation Mechanisms During the Late Quaternary: An Example From the Lower Cerovačka Cave, Croatia

Frontiers in Earth Science, 2021
During archeological excavations in the Lower Cerovačka Cave (Mt. Velebit, Croatia), the test trench penetrated to a depth of 1.8 m. An undisturbed sequence of sediments was exposed. Considering that caves represent highly efficient sediment traps it was

The Assessment of Organic Matter Young's Modulus Distribution With Depositional Environment and Maturity

Journal of Geophysical Research: Solid Earth, Volume 125, Issue 12, December 2020., 2020
Abstract Quantification of risk to seal integrity in CCS, or gas extraction from hydraulic fracturing, is directly affected by the accessibility of organic pores within organic rich mudrocks. Knowledge of the host organic matter's mechanical properties, which are influenced by depositional environment and thermal maturity, are required to reduce ...

Turbidite‐induced re‐oxygenation episodes of the sediment‐water interface in a diverticulum of the Tethys Ocean during the Oceanic Anoxic Event 1a: The French Vocontian Basin

The Depositional Record, Volume 6, Issue 2, Page 352-382, June 2020., 2020
The oceanic anoxic event OAE1a episode has been recorded in the Vocontian Basin (SE‐France) but recurrent reworking (turbidites) altered the record. Abstract Widespread anoxic events affected the Tethys Ocean during the Mesozoic. The Ocean Anoxic Event 1a (Early Aptian), expressed as the Selli Level or Goguel Level (GL) in European basins.

The prospectivity of a potential shale gas play: An example from the southern Pennine Basin (central England, UK) [PDF]

, 2017
During the Serpukhovian (late Mississippian) Stage, the Pennine Basin, now underlying much of northern England, consisted of a series of interlinked sub-basins that developed in response to the crustal extension north of the Hercynic orogenic zone.
