A fluid flow perspective on the diagenesis of Te Aute limestones [PDF]
, 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.

Amino acid racemization dating: Method development using African ostrich (Struthio camelus) eggshell [PDF]
, 2013 Ostrich eggshell (OES) is ubiquitous in archaeological sites in Africa and is a favoured substrate for amino acid racemisation (AAR) geochronology, yielding consistent results and thought to approximate a closed system with respect to protein diagenesis.

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 [PDF]
, 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 ...

American Journal of Botany, EarlyView.Abstract Premise The modern distribution of the southern cypresses, Callitroideae (Cupressaceae), reflects a classic Gondwanan distribution. The initial diversification of Callitroideae is estimated to have occurred during the Cretaceous, yet fossils from this period are rare, hampering our understanding of its early evolutionary history.

3-D seismic investigation of the diagenesis and deformation of Cenozoic siliceous sediments on the Eastern Atlantic Margin [PDF]
, 2011 Three-dimensional seismic data from the East Atlantic Margin are used to investigate the diagenesis and deformation of siliceous sediments. Three themes were tackled.

Chemical controls on incipient Mg-silicate crystallisation at 25oC : implications for early and late diagenesis [PDF]
, 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.

Diagenesis of archaeological bone and tooth [PDF]
, 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 ...
