The weathered granite is overlain by a shaly regolith and the Lamotte sandstone overlaps this irregular surface. form such a formidable obstacle to the idea of a 6000 year old earth and a global flood that most creationists either ignore these topics, or offer outlandish peripheral refutations of the ideas (more on these in a a later paragraph).This photo is updated as the old photo was improperly formatted (the update was made solely to provide proper perspective and to highlight the absurdity of Tas Walker's 'analysis' rather than to Walker's blustering about 'changing the story'). What is it about these topics that send ye-creationists running for the cover?
It is not about the theory behind radiometric dating methods, it is about their , and it therefore assumes the reader has some familiarity with the technique already (refer to "Other Sources" for more information).
As an example of how they are used, radiometric dates from geologically simple, fossiliferous Cretaceous rocks in western North America are compared to the geological time scale.
To get to that point, there is also a historical discussion and description of non-radiometric dating methods.
The science of geology is founded on basic principles that are useful for making observations about the world around us.
This chapter presents a mix of information that is essential (fundamental) to all following chapters.
