Oh Glod, I *had* forgotten accreted terrane! *facepalm* Silly me!

At the moment, the rough structure I"m thinking is a fairly simple cyclic sedimentary sequence that's been uplifted and tilted to the southeast, and probably limestones capping with softer mudstones underneath giving us dipslopes, but I'm also toying with putting some antiforms and synforms in, tilting THAT and then eroding off to get the mountains. More complicated, but results in a prettier map, which is always of the good!
