Re: Igneous rock over sedimentary layers
Faith writes: Lava has burbled up through sedimentary layers and spilled over them in many locations. The Grand Canyon even. The Siberian traps. Sometimes forming sills between layers, sometimes just pushing up to the top and forming lava fields. Those cases are not used to date the underlying layers are they? They could be used to date overlying layers, right?

Re: Igneous rock over sedimentary layers
The issue would be the presence of significant unconformities beneath or above the lava flows. I would be very careful about either unless I was in a fairly continuous sequence of sediments briefly interrupted by a volcanic event.
In the case of a sill, the only relationship would be intrusive younger than sediments on either side. Sure, that makes perfect sense. I assume that ash layers are the best, from a geology dating standpoint, because they can cover much wider areas than lava flows.

Re: Moderator Provided Information, that's wrong
Faith writes: You do not explain the even layering. You call this even layering? If so, I have to wonder what you would call uneven layering?

Re: Moderator Provided Information, that's wrong
Faith writes: Yes, it's been tectonically jostled but the layers were clearly originally laid down flat and of a pretty even thickness. I don't know what kind of clues you see in the photo that tells you they were clearly originally laid down flat. I guess you mean equal thickness when you say even thickness. They do not look equal in thickness to me, but if they were, why is that significant? Is there some principle of geology that they should or should not be of equal thickness? I'm curious, how many layers do you see in the photo?

Re: Moderator Provided Information, that's wrong
You will notice that she never does answer your question. Looking back over the past couple of years we get a lot of that from Faith. She makes an initial comment that really does not make sense and never clarifies or explains what she meant, when asked. Now that Percy has ruled that she cannot use arguments that were refuted in past threads, I guess we will not be hearing much from her in geology or biology/evolution discussions.
