A Giant Slide within the Upper Cretaceous Limestones as an Indicator for Fault Activity Dating and Basin Evolution

Proceedings, 2023
The studied section, up to 10 m thick with 17 different carbonate beds, showed the interaction between a giant slide and the pre-existing normal faults during the upper Cretaceous time. There are three major points of consideration in the studied section:

Trace element delivery for biogas production enhanced by alternative energy crops: results from two-year field trials

Energy, Sustainability and Society, 2018
Background Energy crop production for biogas still relies mainly on maize, but the co-digestion of alternative energy crops (legumes, amaranth, ryegrass, flower mixtures) with maize can have several advantages. First, a greater biodiversity in the fields;

Morphometric convergence between Proterozoic and post-vegetation rivers [PDF]

, 2017
Proterozoic rivers flowed through barren landscapes, and lacked interactions with macroscopic organisms. It is widely held that, in the absence of vegetation, fluvial systems featured barely entrenched channels that promptly widened over floodplains ...

Controls of depositional facies and diagenetic alterations on reservoir quality of the Fahliyan Formation in the Central Zagros area [PDF]

Journal of Stratigraphy and Sedimentology Researches, 2020
The Fahliyan Formation is a member of the Khami Group with Neocomian–Barremian age. In two surface sections in the Izeh Zone and two wells of the southern Dezful Embayment, it includes 12 microfacies deposited on four facies belts as tidal flat, inner ...

Sedimentary record from the Canada Basin, Arctic Ocean: implications for late to middle Pleistocene glacial history [PDF]

Climate of the Past, 2017
Sediment core ARC4-BN05 collected from the Canada Basin, Arctic Ocean, covers the late to middle Quaternary (Marine Isotope Stage – MIS – 1–15, ca. 0.5–0.6 Ma) as estimated by correlation to earlier proposed Arctic Ocean stratigraphies and AMS14C dating ...
