Guide to the nature and methods of analysis of the clay fraction of tephras from the South Auckland region, New Zealand.

, 1983
The manual outlines some of the more common laboratory procedures available for qualitatively and quantitatively analysing the composition of the tephric clays, many of which are difficult to determine because of their short range order or 'amorphous ...

Marine Isotope Stage 4 glaciation in northern England, UK: Evidence from Victoria Cave, North Yorkshire

Journal of Quaternary Science, EarlyView.
ABSTRACT Victoria Cave, north Yorkshire, England, contains a long sequence of Pleistocene clastic sediments and calcite flowstones. Earlier work, using U–Th dating, established that the flowstone units formed in interglacial stages corresponding to Marine Isotope Stages (MIS) 13, 11, 9, 7 and 5.

Farming in the shadows of Rome: A multi‐proxy palaeoenvironmental record from Loch Clunie—Perthshire

Journal of Quaternary Science, EarlyView.
ABSTRACT Roman impacts on local society is a subject of international significance. Loch Clunie, Perthshire, lies only 5.4 km from Inchtuthil, the only Roman legionary fortress in Scotland, and contains two crannogs and a probable lakeside hillfort. Despite this proximity and the likelihood of local–Roman interaction, these sites remain unexcavated ...

Clay-associated organic matter in kaolinitic and smectitic soils

, 2002
The primary source of soil organic matter is plant debris of all kinds, such as dead roots, leaves and branches that enter into the soil and are then biologically decomposed at variable rates.

Raman Line Scan Analyses and a New Hypothesis for the Formation of Anatase‐Hosting Microbialites: Study of the Stromatolites From Saint‐Jean‐de‐la‐Rivière, Cotentin, France

Journal of Raman Spectroscopy, EarlyView.
Micrometer analysis of millimeter lines of Raman spectra concludes in the association of anatase and graphitized organic matter (graphogen). The photosynthetic microorganisms at the origin of the microbialites produce O2, which is transformed by TiO2 into reactive species that, in turn, decompose the organic matter of the microorganisms.
