Students should be able to understand the principles and have that as a background so that age determinations by paleontologists and geologists don't seem like black magic. Geologists in the late 18th and early 19th century studied rock layers and the fossils in them to determine relative age.

William Smith was one of the most important scientists from this time who helped to develop knowledge of the succession of different fossils by studying their distribution through the sequence of sedimentary rocks in southern England.

Clearly, Sedimentary Rocks A were deposited and deformed before the Volcanic Dyke intruded them.

Objectives of this activity are: 1) To have students determine relative age of a geologically complex area.

Oligoclase Oligoclase has the formulae (Na, Ca)Al Si3O8 and a relative hardness of 7. It is found lining and filling cavities in igneous and sedimentary rocks where it's been deposited by hot waters.

It's name is derived from the characteristic olive green colour. A clear green variety is called peridot and has some uses as a gem. Opal Opal has the formulae Si O2n H2O and a relative hardness of 6.

2) To familiarize students with the concept of half-life in radioactive decay.

3) To have students see that individual runs of statistical processes are less predictable than the average of many runs (or that runs with relatively small numbers involved are less dependable than runs with many numbers).
