Petrogenesis and Tectonic Setting of Late Mesozoic Felsic Magmatic Rocks in the Wangmushan Mining District, Northern Fujian, South China

Geological Journal, EarlyView.
The rhyolitic ignimbrite and K‐feldspar granite porphyry from the Wangmushan mining district, northern Fujian yield ages of 173.8 ± 0.8 and 102.6 ± 0.4 Ma, respectively. Geochemical data, zircon trace elements, whole‐rock Sr–Nd–Pb isotope data, and zircon Hf isotopic compositions indicate that the rhyolitic ignimbrite originated from partial remelting ...

Influence of differential diagenesis on pore evolution of the sandy conglomerate reservoir in different structural units: A case study of the Upper Permian Wutonggou Formation in eastern Junggar Basin, NW China

Open Geosciences, 2022
In order to study the differential diagenesis of sandy conglomerate reservoirs in different tectonic units in eastern Junggar Basin, and establish the differential temporal sequence of burial – diagenesis – hydrocarbon charging – pore evolution, the ...

The Carbonate Raman Processing and Plotting Tool: A Software Application for 2‐Dimensional Raman Image Peak‐Fitting and Visualization

Journal of Raman Spectroscopy, EarlyView.
We present the Carbonate Raman Processing and Plotting tool (CaRPP), designed to perform peak‐fitting and visualization on two‐dimensional Raman maps of calcium carbonate specimens. Users begin by providing a raw Raman data file and then interactively use the application to perform peak‐fitting, masking, and 2‐D image generation.

Diagenesis of marine-continental transitional shale from the Upper Permian Longtan Formation in southern Sichuan Basin, China

Open Geosciences
Upper Permian Longtan Formation transitional shale has become an important exploration layer, but the Longtan Formation shale (LFS) has a complex mineralogical composition, which affects the subsequent diagenesis and diagenetic evolution, and restricts ...

Soft-Tissue, Rare Earth Element, and Molecular Analyses of Dreadnoughtus schrani, an Exceptionally Complete Titanosaur from Argentina

Biology, 2022
Evidence that organic material preserves in deep time (>1 Ma) has been reported using a wide variety of analytical techniques. However, the comprehensive geochemical data that could aid in building robust hypotheses for how soft-tissues persist over ...

Let's Talk About Bone Cylinders. Taphonomy of Carnivores and Humans

International Journal of Osteoarchaeology, EarlyView.
ABSTRACTBone cylinders are a distinctive structure predominantly produced by durophagous carnivoran species during the consumption of long bones, in which the diaphyseal canal remains intact while both epiphyses are removed or consumed. This study evaluates the significance of this morphology, traditionally attributed to extant and extinct hyena ...

Organic matter maturation vs clay mineralogy: A comparison for Carboniferous to Eocene sediments from the Alpine – Dinaride junction (Slovenia, Austria)

Geologija, 2002
Clay mineral diagenesis of Carboniferous to Paleogene rocks within the Alpine-Dinaric junction was studied and compared to vitrinite reflectance. Generally, there is a good fit between clay mineral diagenesis and VR. However, clay mineral alterations lag

Study of Diagenesis and Pore Evolution of Triassic Jialingjiang Formation in Southern Puguang Gasfield

Journal of Chemistry, 2016
The second member of Jialingjiang formation is considered to be an important gas reservoir with good exploration prospects in the southern Puguang gasfield. The diagenesis types are analyzed and different diagenetic stages are divided by analyzing carbon
