I understand what formation is, but i dont understand what deformation is, and how it relates to original horizontality. could someone exlpain?

I think I can help with the first part of your question: Deformation is caused by tectonic activity along faults, causing 2 things to happen... -physical alterations caused by the rocks slipping and grinding past each other, making fragments. -resulting pressure causes recrystallization

There are two textures that result from this - Cataclastic - near the surface Mylonitic- farther down where there is more heat and pressure (text pg 178 for more on mylonites)
