The origin of water‐borne diamictons and their relation to turbidites [PDF]
Summary The term “diamicton” has recently been proposed as a non‐genetic name for any non‐calcareous terrigenous sediment containing a wide variety of grain sizes; the lithified equivalent is a “diamictite.” The present paper deals with the origin and classification of water‐borne diamictons. The latter have been divided by the writer into three groups:

Modelling Phosphorus for Grassland: Agronomically and Environmentally Sustainable Advice [PDF]
End of project reportIn 2006, the Nitrates Directive (through S.I. 378 (Anon, 2006)) was implemented in Ireland, aimed at reducing nutrient losses from agriculture to water bodies, i.e. surface waters, groundwater and estuarine waters.

Internal structure and significance of ice-marginal moraine in the Kebnekaise Mountains, northern Sweden [PDF]
Despite a long history of glaciological research, the palaeo-environmental significance of moraine systems in the Kebnekaise Mountains, Sweden, has remained uncertain.

Map of Lower sediment (LS) thickness is a surrogate for the distribution of Thorncliffe Formation (TF) and ~75% of TF thickness from the slope of Niagara Escarpment east to Brighton. Inset images show the LS sequence at the Don Valleys brickyards (DVBY) and undeformed TF sand and gravel (~15 m) below Newmarket Till (NT) at sites L and Co.

Effective and sustainable land use, conservation, and the use of geological resources (incl. raw materials, aggregates and groundwater) require a clear classification system of sedimentary units, with well‐defined vocabulary and unified mapping practices.

We provide a geomorphological analysis of Cordillera Vilcanota and use morphostratigraphic principles to reconstruct palaeo icefield extent and palaeoglacier readvances, likely during the Antarctic Cold Reversal and Younger Dryas. We find evidence of temperate and polythermal ice margins, with limited glaciofluvial landform generation.

ABSTRACT The sedimentary succession at Whittlesey preserves a unique British late Middle Pleistocene to Holocene record back to a time equivalent to at least marine oxygen isotope stage 8 (ca. 250 ka). This study builds on previously published sedimentology, geochronology and palaeoecology results to establish 20 sedimentary facies associations, with ...

Nouvelle séquence glaciaire antérieure aux Sédiments de Saint-Pierre, Sainte-Anne-de-la-Perade, Québec [PDF]
Trois nouvelles unités, d'origine glaciaire et glaciolacustre, antérieures aux Sédiments de Saint-Pierre, sont définies sur la rive nord du Saint-Laurent, entre Sainte-Anne-de-la-Pérade et Grondines.

Summary When Rome colonized Britain, it created a transport network spanning the province. This transformed the Iron Age economy, creating large new markets which in turn supported specialized manufacturing. This article explores the impact of transportation on Roman agriculture – the core of the Romano‐British economy.
