While classically orbital cycles have been recognized in pelagic and lacustrine sequences characterized by quiet sedimentation, not disturbed by tectonics, there is now an increasing recognition of the fact that orbital cycles do influence climate and oceanography in general terms. There is also increasing acceptance of the possibility at least that the effect should be felt over large parts of the Earth's surface and that orbital cycles may well leave signs in other sedimentary environments which commonly are considered to be dominated by tectonics and eustasy. Containing thirty-one papers from a symposium held at the International Sedimentological Congress in Nottingham in 1990; this volume spans a range of topics from the astronomical theory behind orbital forcing, to field studies
