Clastic sedimentary records provide important information about the nature of the depositing media, especially as related to the energy under which deposition occurred and the source and flux of sediments. In some cases, sediment characteristics or sequences reveal important insight into past precipitation, temperature, and wind regimes; in many cases, however, there are alternative climatic interpretations, as well as non-climatic explanations. A multi-proxy approach is needed, and the use of biota and isotopic signatures in interpreting clastic sequences is important. Abrupt changes in climate proxies may indicate abrupt climatic change but, without detailed chronostratigraphic control, may only reflect a missing interval during which a gradual change occurred.
