PART 1: DETERMINING ABSOLUTE GEOLOGIC AGES Go to the Virtual Dating Web page and earn your Virtual Radiochronologist Certificate by completing the exercise entitled Virtual Dating Isochron for rocks and minerals.This follows due to the fact that sedimentary rock is produced from the gradual accumulation of sediment on the surface.Therefore newer sediment is continually deposited on top of previously deposited or older sediment.Older materials have so little carbon-14 left that it cannot be accurately measured.Thus, carbon-14 is of no use in determining the absolute ages of, for example, dinosaur fossils.The Principle of Fossil Succession states that groups of fossils (called fossil assemblages) proceed one another in a regular and determinable manner.In Part 2 you will use the principles of relative dating to determine sequences of geological events as indicated by the layers and structures in the rocks.Remember that unconformities represent sections of missing time, either through non-deposition of rocks for a period of time, or through an interval of erosion which has removed some strata.(Strata are layers of rock.)The three different types of unconformities are shown in the textbook (refer to the index of the book to find where).The only materials that start out with usable amounts of carbon-14 in them are carbon-bearing materials which derived their carbon immediately from the atmosphere or from shallow water.This means that the remains of living things are useful for carbon-14 dating.
