Department of Earth Sciences, University of Bristol: Isotope Geochemistry: Introduction. The course is divided into a series of modules that are designed to be tackled in order. Each module explains a particular topic and is followed by a test which is designed to examine your understanding of the material.

Science of Earth Systems (SES), Cornell University (the Colleges of Agriculture and Life Sciences, Arts and Sciences Engineering, Department of Earth and Atmospheric Sciences, Department of Astronomy, Department of Natural Resources, Department of Ecology and Evolutionary Biology, Department of Agricultural and Biological Engineering, School of Civil and Environmental Engineering): Evolution of the Earth System. This course describes highlights of the co-evolution of life and the physical/chemical Earth system: Go to: Lab 2 Radioactive Decay, Isochrons, and Geologic Time, and Stable Isotopes as climatological and paleontological tools.

Earth Science Australia: Geological time. Worth to visit: Radioactive Isotopes - the "Clocks in Rocks", etc.

Mike Fowler and Roger Suthren, Geology, Oxford Bookes University: Introduction To Geology. See the teaching and learning materials index, Lecture support material.

Pamela J.W. Gore, Georgia Perimeter College, Clarkston, GA: Radiometric Dating. Educational materials on the topic in brief.

Mark Gregory, Sydney: Carbon 14 Dating Calculator. To find the percent of Carbon 14 remaining after a given number of years, type in the number of years and click on Calculate.

Tom Higham, Radiocarbon Laboratory, University of Waikato, New Zealand: The Radiocarbon WEB-Info. This resource is designed to provide online information concerning the radiocarbon dating method. Radiocarbon dating is the technique upon which chronologies of the late Pleistocene and Holocene have been built.

Gabriele Kastl, Thomas Engbarth, Museum für Ur- und Frühgeschichte, Freiburg/Breisgau, "Web-Museen": Death starts the stop-watch. Carbon-14 method, briefly explained.

Justin Matis and Richard B. Firestone, Ernest O. Lawrence Berkeley National Laboratory, Berkeley: Glossary of Nuclear Terms. With animated images to illustrate the nuclear decay.

Gary A. Novak, Department of Geological Sciences, California State University at Los Angeles, Geology Labs On-Line: Virtual Dating. These virtual labs are interactive where students learn by "doing" and not just clicking and viewing. Virtual Dating models the theory and processes whereby ages of older rocks (> 100 million years) are determined from the Isochron method applied to Rb/Sr isotopic compositions. This activity also includes a C-14 option for once-living materials that are less than 50,000 years old.

William L. Newman, USGS Geologic Information - General Interest Pubs, U.S. Department of the Interior, U.S. Geological Survey: Geologic Time. This online edition contains chiefly all text from the original book in its entirety.

Paul Eric Olsen, Department of Earth and Environmental Sciences, Columbia College of Columbia University (Lamont-Doherty Earth Observatory): Unraveling Geological Time. Lecture 2, Online Course EESC V1001, "Dinosaurs and the History of Life".

Dennis O'Neil, Palomar College, San Marcos, California: The Record of Time. An introduction to the world of fossils and dating methods.

Radiocarbon. Radiocarbon is the main international journal of record for research articles and date lists relevant to ¹⁴C and other radioisotopes and techniques used in archaeological, geophysical, oceanographic and related dating.

Malcolm Reeves, Ben Rostron and Doug Stead, Department of Geological Sciences, University of Saskatchewan, Canada: Geology for Engineers, Index and Outline. Go to: Geological Time (Click "Next" for: Relative Dating, Correlation, Absolute Dating, Radiometric Methods, Time Scales).

ScienceProf.com: Free samples for evaluation, Magnetic Reversal. A shockwave flash animation. During periods of normal magnetism, north-seeking magnetic poles point towards geographic North. During reversals, they point South. As the mid-ocean ridge spreads, the magnetic field is frozen into lava as it cools through the Curie point, preserving a record of magnetic field reversals going back millions of years. Magnetic stripes are irregular due to the rough shapes of intrusives and extrusives. Those shown here are based on real data from the Atlantic crust south of Iceland.

Tim Thompson: A Radiometric Dating Resource List.

Department of Geology and Geophysics, University of Utah, Salt Lake City: Exploring the Earth, demonstrations of fundamental Earth processes. Radioactive Decay. A Java applet. Watch an element decay through time from the initial radioactive parent to the final nonradioactive daughter. Select the desired decay series by clicking on the button in front of that series. Either run the simulation in the Animate mode which automatically picks the time step for the decay process, or run the simulation with your own time step.

US Geological Survey and the National Park Service: USGS Geology in the Parks, What is Geologic Time? See also: Age of the Earth, Radiometric dating (PDF file). Overview of evidence for a 4.55 billion year age of the Earthand of radiometric dating techniques. Written at upper high school to college level. See also: Geologic time scale (DNAG). PDF file. Black and white version of Decade of North America time scale.

W. White, Department of Geological Sciences, Cornell University, Ithaca, NY: Geo Sci 656 Lecture Notes. A set of lecture notes for a course in Geochronology, Radiogenic Isotope Geochemistry and Stable Isotope Geochemistry. You can view and print the following documents using Adobe Acrobat Reader. Go to:
Isotope Geochemistry. The lecture note (Adobe Acrobat Reader Version 3) covers the following topics: Nuclear structure and nucleosynthesis and the origin of the elements, geochronology, isotope ratios as natural tracers and stable isotope geochemistry.
