points i've taken in so far ...
this folding is not just local ... it was part of an event that affected a great part of the european land mass, and parts of north america and north africa whilst they all pushed up together
it happened long long ago and took a very long time ... all the folding and tilting and faulting and thrusting might have taken one hundred million years ... in very slow motion
when these rocks were being compressed and folded, they were a long way from where we stand today ... the earth's crust is made of great rafts that drift and are pushed and pulled across the surface of the globe ... the strata were probably a bit softer then
the question i have is this ... were these rocks formed ... compressed and consolidated ... at some depth ... what other rocks might have pressed down on them ?
