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!
