Stable oxygen and carbon isotope compositional fields for skeletal and diagenetic components in New Zealand Cenozoic nontropical carbonate sediments and limestones: A synthesis and review

, 1996
The stable oxygen isotope composition (δ18O) of a precipitated carbonate depends mainly on the isotope composition, salinity, and temperature of the host fluid, whereas the stable carbon isotope composition (δ13C) reflects the source of CO2 for ...

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 ...

Limits of calcium isotopes diagenesis in fossil bone and enamel

, 2023
International audienceDiagenesis has been recognized for decades to significantly alter the trace elements biogenic signatures in fossil tooth enamel and bone that are routinely used for paleobiological and paleoenvironmental reconstructions.

Drilling the Marathousa palaeo‐lake in Greece (Peloponnese): inferring the environmental context of a Middle Pleistocene archaeological site

Boreas, EarlyView.
The Megalopolis Basin is located in the central Peloponnese (Greece), a region that is situated along one of the primary Pleistocene biogeographical corridors for intracontinental hominin migration. The basin comprises several hundred metres of Plio‐Pleistocene sediments alternating between clastics and lignites.

A study of the effects of early diagenesis on the geotechnical properties of carbonate sediments (North West Shelf, Australia)

Scientific Reports
Carbonate sediments are often regarded as problematic in geotechnical engineering due to the high variability of their properties. Understanding and quantifying this variability will become increasingly critical in the years ahead, notably with respect ...

Variation of Visean strata across the midi thrust, Belgium [PDF]

, 1986
The Viséan strata of southern Belgium, between Namur, Aachen, Comblain-au-Pont and Dinant, record the deposition of shallow water carbonates along the southern margin of the Brabant Massif.

Imaging Point Source Groundwater Discharges in a Confined Coastal Aquifer Using Electrical Resistivity

Groundwater, EarlyView.
Marine electrical resistivity tomography (ERT) is applied to characterize point‐source submarine groundwater discharge (PSGD) along NW Yucatán. ERT observations and forward modeling constrain conduit detectability under varying hydrogeological conditions.

Chemical controls on incipient Mg-silicate crystallisation at 25oC : implications for early and late diagenesis

, 2014
Mg-silicate minerals (e.g., stevensite, kerolite, talc, sepiolite) play an important role in the construction of facies models in lacustrine and peri-marine environments because they are sensitive to changes in solution chemistry.

Confirming the impact origin of the São Miguel do Tapuio structure, northeastern Brazil

Meteoritics &Planetary Science, EarlyView.
Abstract The São Miguel do Tapuio structure (SMT) is a remarkable, nearcircular feature of about 21 km diameter, centered at 5°37.6′ S, 41°23.3′ W in Piauí state, northeastern Brazil. The structure is located within the sedimentary strata of the Paleozoic–Mesozoic Parnaíba Basin and predominantly comprises sandstones of the Devonian Pimenteiras and ...
