I have no idea what would cause the different textures here, but perhaps one of the geology geeks has an opinion?

Rob's answer is pretty close. Those holding a short ticket to Hell, however, would say that it is all about grain size--the more broken up layers have more silt and clay while the more "massive" layers are sandier. But what do I know--I'm not one of those "evil-lutionists".
