It basically says there can't be a "complete set" of conformable strata because there's also sorts of dynamics (faulting, folding, erosional processes) that would make it near impossible to have a perfectly conformable set of strata. I think it's something along those lines. Since nomynameisnotkevin didn't seem to respond, Gemma W or someone else here want to go?
Yes, sorry, was MIA for a while.
exactly, there can't be a "complete set".

The frictional movements of rocks during faulting creates what type of lineation?

Err, I don't know what that means, but does nobody know this? Would an image help?

Indeed (thank you for finally answering)!

No problem.
The following are measurements of five lineations, taken at five different outcrops.
If these lineations are elements of a planar fabric within the rock, then they should all lie within the same plane. If you find this to be true, what is the attitude of that plane?

Given three outcrops, their elevations, and their distances, calculate the dip of the bed to the nearest whole number. Drawing's not to scale so you'll have to math it out on your own.
Hey guys, it doesn't seem like the answer for this question was posted, so could someone give me feedback on my answer?
dip= 31

You probably found the apparent dip. That is around 31. I found true dip to be roughly 37.
