Relative Dating - working out what happened first, second...

How does a geologist work out the sequence of events when looking at outcrop?  How do uniformitarianism, superposition, fossil sequences, and cross-cutting relationships all tie together to work out what came first and what came last?  This episode I talk through the processes for sedimentary, igneous and metamorphic rocks and structures like faults, folds, and unconformities.All of that in just 12 mins!You can find the GEO podcast on iTunes right here.And go and visit www.geoetc.com!Support the show
