Also you mentioned chemical and mechanical weathering in the context of the production of the sediment; but don't those processes also occur during and after lithification? And don't those characteristics give us clues as to the depositional environment?
Yes, however, the breakdown of rock to producing clastic sediments is kind of the opposite to lithification.
I guess I didn't understand the question. About chemical and mechanical weathering occurring during lithification, since lithification occurs after burial, how could there be any weathering? And about after lithification, can't weathering only occur after exposure?
