To illustrate tension (associated with normal faults) have them gently pull on the edges of the candy bar.They will notice that the "plates" move apart to reveal the caramel/nuts or "asthenosphere".What would the geologist be able to deduce about the world we live in, based on what was left in the strata?Stratigraphy started to become a formal science due to the work of a man who published under the name Nicolaus Steno in the 17th century.Steno made careful geologic observations and illustrations.He published the results of his work and established a basic set of principles for interpreting sedimentary strata.(pdf) - Take your students on a journey through the mineral world!

(a) Relative Dating This technique uses principles of stratigraphy (rock strata) and the study of fossils (palaeontology) to determine the relative ages of rocks and sediments. Field geologists' rely on a number of simple techniques for dating rocks and constructing geological successions. The Law of Strata Identified by Fossils is a little bit more complex.Geologists still use Steno's principles, with some refinements and additions.They are summarized as the Principles of Relative Geologic Age Determination, sometimes referred to as the Principles of Relative Dating.For example, if you have one type of organism that lived 10 million years ago and it is found within one geologic layer, then you have a better clue of the age of that layer.Such fossils are called In June, it is almost a certainty that you will have to answer questions that asks you the order of geologic events.The table below summarises key features: Gastrioceras listeri is a particularly good example of a ZONE fossil.As it is free swimming it could have travelled a considerable distance.Geologists use several principles to find the relative age of geologic layers. Remember, contact metamorphism is changes in a rock due to contact with magma or lava.- The principle of superposition is simply the fact that the lowest layer of a rock formation is the oldest layer while the youngest layer is towards the top. Think of it as a boundary layer between igneous rocks and sedimentary rocks.The diagram right shows two distinct faunal assemblages.What can be deduced from our two distinct faunas in terms of their usefulness in the relative dating of rocks?
