Integrative Zoology, EarlyView.This study provides the first isotopic analysis of Oligocene mammals from Quebrada Fiera, Mendoza, Argentina, filling a major gap in South American paleontology. It reveals a latitudinal gradient in aridity due to the Andean rain shadow and highlights the role of (semi)permanent water bodies in sustaining diverse herbivore communities. Additionally, it

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

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

A Diagenetic Study of the Wolfcamp Shale in the Midland Basin, West Texas [PDF]
, 2016 The lower Permian Wolfcamp Shale is a major unconventional resource play in the Permian Basin. Near the eastern margin of the Midland Basin the Wolfcamp Shale is comprised of calcareous and siliceous mudstones interbedded with carbonate turbidites and ...

Diagenesis of archaeological bone and tooth
, 2022 An understanding of the structural complexity of mineralised tissues is fundamental for exploration into the field of diagenesis. Here we review aspects of current and past research on bone and tooth diagenesis using the most comprehensive collection of ...

Archaeometry, EarlyView.ABSTRACT Provenance reconstruction using strontium and lead stable isotopes can produce complex multidimensional fingerprints, challenging traditional methods. Identifying nonlocals, who migrated between sites, is a major task. Migrants are identifiable by divergent multi‐isotope fingerprints due to isotopic mixing between origin and destination sites.

A fluid flow perspective on the diagenesis of Te Aute limestones
, 2003 Pliocene cool-water, bioclastic Te Aute limestones in East Coast Basin, New Zealand, accumulated either in shelfal shoal areas or about structurally shallow growth fold structures in the tectonically active accretionary forearc prism.

Archaeometry, EarlyView.ABSTRACT Cremation became the dominant funerary practice in the Middle Danube Region during the Roman Period (RP) (1st–4th century) and reappeared in the Early Medieval Ages (EMA) (6th/7th–8th century). This study aims to reconstruct differences in cremation conditions from the Gbely‐Kojatín site (Slovakia, RP and EMA) and the Přítluky site (Czech ...

Hydrodynamics, Diagenesis and Hypoxia Variably Drive Benthic Oxygen Flux in a River‐Reservoir System
Water Resources ResearchBenthic oxygen flux with complex spatiotemporal variations is essential for the global budget of carbon dioxide and the regional security of water quality and ecology, but its dominant driver under different circumstances has yet to be identified.

Burial Diagenesis in Limestones
As carbonate sediments become buried, major changes in fabric, composition, rigidity and porosity tend to occur. Character of burial diagenesis is controlled by precursor sediment character, pore fluid, lithostatic and tectonic stresses, evolving aqueous
