An important key to the Principle of Original Horizontality is that

it applies to igneous rocks only.

it applies to layers that have not been deformed or disturbed.

Superposition must be applied first.

this principle governed the formation of rock layers in the past, but does not apply to the present.

Hi! If you can post this question in a science section, that would be great! I believe at the moment the only place you can post this is in the Biology group! Let me link that to you!
