Mudstone diagenesis and sandstone provenance in an Upper Jurassic – Lower Cretaceous evolving half-graben system, Wollaston Forland, North-East Greenland

GEUS Bulletin, 2023
The influence of rifting on the composition of Kimmeridgian to Barremian mudstones from northern Wollaston Forland, North-East Greenland is investigated by petrographic and mineralogical analyses of the Brorson Halvø-1 and Rødryggen-1 cores, and ...

Quantitative provenance analysis through deep learning of rare earth element geochemistry: A case from the Liuling Group of the East Qinling Orogen, Central China

Frontiers in Earth Science, 2022
With the ever-growing availability of massive geo-data, deep learning has been widely applied to geoscientific questions such as sedimentary provenance analysis. However, randomly selected initial weights (and also biases) and possible loss of population

Disentangling Combined Effects of Sediment Sorting, Provenance, and Chemical Weathering From a Pliocene‐Pleistocene Sedimentary Core (CSDP‐1) in the South Yellow Sea

Geochemistry, Geophysics, Geosystems, 2021
The South Yellow Sea is an important sink for sediments delivered by the Yellow and Yangtze rivers in East Asia. We conducted a high‐resolution geochemical analysis on the bulk sediments retrieved from a marine drill core (CSDP‐1) using the method of X ...

Discrimination of Clinozoisite–Epidote Series by Raman Spectroscopy: An application to Bengal Fan Turbidites (IODP Expedition 354)

Geosciences, 2022
Epidote group minerals are one of the three most abundant kinds of heavy minerals in orogenic sediments, the other two being amphibole and garnet. They resist diagenesis better than amphibole and resist weathering in soils better than garnet.

Sedimentary characterization and provenance analysis of the 2018 flooding along the Dan River, Shandong, and the hydrodynamic process reconstruction

Dizhi lixue xuebao, 2022
Sedimentary characterization of modern floods helps to reconstruct the hydrologic flood process and spot the source area of sediment erosion. It is of great referential value both to the design of flood-control works and the identification of paleo-flood

Provenance Inference for Instagram Photos Through Device Fingerprinting

IEEE Access, 2020
Sensor pattern noise (SPN) has been extensively studied in the scientific community and has found its applications in many practical scenarios in the law-enforcement sector. However, the emergence of photo-sharing social networking sites (SNSs) poses new

Luminescence Sensitivity of Quartz From Rocks Under in situ Chemical Weathering Conditions

Frontiers in Earth Science, 2022
In provenance investigation of Quaternary sediments, quartz luminescence sensitivity (QLS) has been employed as a technique. The weathering and influence on the earliest signs of luminescence sensitivity of sedimentary quartz require more consideration ...

Detrital Mica Composition Quantitatively Indicates the Sediment Provenance along the Subei Coast to the Yangtze Estuary

Applied Sciences, 2022
The influence of large rivers on the Subei littoral plain area requires more research than the results that have been available up to now. Thus, specific diagnostic indices of detrital mica are successfully applied for the first time to identify the ...
