Abstract The Quaternary spans approximately the last two million years (Fig. 4K.1). In Canada, it is associated with glaciation, and the Interior Plains display a glacial record that may be unrivalled for detail and completeness. This review gives a synopsis of the period; a fuller account is found in Chapter 2 (Klassen, 1989; Vincent ...

Abstract The Quaternary is represented widely over land areas and sea floors around Britain by sediments formed under conditions which ranged from warm temperate to glacial, humid to semi-arid, and which involved glacial, periglacial, fluvial, mass movement, marine and aeolian processes.

Quaternary Plotkin Constructions and Quaternary Reed-Muller Codes
2007New quaternary Plotkin constructions are given and are used to obtain new families of quaternary codes. The parameters of the obtained codes, such as the length, the dimension and the minimum distance are studied. Using these constructions new families of quaternary Reed-Muller codes are built with the peculiarity that after using the Gray map the ...

Abstract In the Cenozoic, the continents of the northern hemisphere shifted towards the North Pole, and Antarctica occupied the south polar section. This situation, plus climatic changes, were favourable for the formation of the permanent polar ice sheets of Arctica and Antarctica in the Pliocene and Miocene, respectively.

A wide range of previously used stratigraphic terms for Queensland’s terrestrial Quaternary deposits were mentioned by Woods (1960), but many are considered invalid and few are in modern usage (Molnar & Kurz 1997). By necessity, the following discussion focuses on the spatial and temporal occurrence of broad geological features, rather than specific ...

AbstractIn designing the contents of this chapter I adopted a personal view, for the subject is highly diversified and seems to be too large for a systematic or comprehensive review. I focus on facets of the subject that have stimulated my curiosity and sense of history and have reinforced my holistic view of environmental change, but I also deal with ...
