This group is dedicated to providing information about the scientific method as it concerns the idea of evolution in the Creation/Evolution debate.

The site provides background information about stratigraphic principles and relative time, biostratigraphy (using fossils for relative dating), and radiometric dating.

Isochron dating is a common technique of radiometric dating and is applied to date certain events, such as crystallization, metamorphism, shock events, and differentiation of precursor melts, in the history of rocks.

Isochron dating can be further separated into mineral isochron dating and whole rock isochron dating; both techniques are applied frequently to date terrestrial and also extraterrestrial rocks (meteorites).

All forms of isochron dating assume that the source of the rock or rocks contained unknown amounts of both radiogenic and non-radiogenic isotopes of the daughter element, along with some amount of the parent nuclide.

Radioactive decay has become one of the most useful methods for determining the age of formation of rocks.

However, in the very principal of radiometric dating there are several vital assumptions that have to be made in order for the age to be considered valid.

The idea of radioactive decay and half lives, a type of absolute dating, is shown through an activity using M&M's candy and graph paper. Sequencing Time, University of California, Berkeley. This 5-12-grade activity lets students place parts of their own life story into a time line so that they can better understand how geologic time is reconstructed by scientists.

Who's on First, University of California, Berkeley. This website is a book chapter about geologic time. This online version of their informative booklet contains short, content explanations about relative time, major geologic time divisions, index fossils for use in age dating, radiometric dating and the age of the earth.

The advantage of isochron dating as compared to simple radiometric dating techniques is that no assumptions are needed about the initial amount of the daughter nuclide in the radioactive decay sequence.

  1. Just days after Anna Wintour swapped lives with Amy Schumer for the Vogue original short in honor of the July issue, our Editor in Chief seemed to be taking cues from the cover girl who, in Wintour’s words, tells it like it is. In the latest installment of the Vogue podcast, Vogue Executive Director of Communications Hildy Kuryk and Vogue Senior Editor Taylor Antrim catch up with two reporters following Hillary Clinton on the 2016 presidential campaign trail: Amy Chozick...
