Can parent rock features such as sedimentary structures and fossils survive low-grade metamorphism?
A)Yes, because the shells of the organisms are strong enough to withstand directed pressure.
B)No, because the sediments and organic materials will be melted.
C)Yes, because such features can withstand low temperatures and pressures but will be destroyed in higher metamorphic grades.
D)No, because even low-grade pressure is too much for such delicate features.
