Tracing Identity in a Fragmented Past: Multi‐Proxy Analysis of Human Skeletal Remains From Dungowan Creek, New South Wales, Australia

Archaeometry, EarlyView.
ABSTRACT Human skeletal remains constitute critical archaeological evidence for reconstructing past societies, yet their investigation requires careful ethical, cultural, and legislative consideration. This paper reports on the discovery, recovery and analysis of a set of skeletal remains encountered during a cultural heritage management (CHM ...

Sedimentary environment, sequence stratigraphy, diagenesis and geochemistry of the carbonate Ruteh Formation in north of Mahabad section [PDF]

Journal of Stratigraphy and Sedimentology Researches, 2019
The Ruteh Formation is the second sedimentary cycle in Alborz basin. The petrography and laboratory studies of these deposits led to the identification of 15 microfacies which were deposited in seven sub-environments including supratidal, intertidal ...

Feldspar Albitization With Implications for Reservoir Quality Evolution of Eocene Turbidite Sandstones in Offshore Espírito Santo Basin, Eastern Brazil

Journal of Petroleum Geology, EarlyView.
ABSTRACT The diagenetic albitization of plagioclase and K‐feldspar grains is a transformative process that significantly alters sandstone's detrital composition and formation water chemistry, impacting reservoir quality. In this study, Eocene turbidite sandstones from the offshore Espírito Santo Basin, Brazil, were investigated to elucidate the role of

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 ...

Diagenetic Study of Marrón Emperador Ornamental Stone (Upper Cretaceous, SE Spain)

Applied Sciences, 2023
The “Marrón Emperador” ornamental stone is known for its characteristic deep brown colour filled with white spots and veins. It consists of a brecciated dolostone with different generations of calcite/dolomite veins and veinlets that represent repeated ...

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

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 ...
