Catalyst: How metamorphic rocks are formed
TLF ID M016026
Imagine the forces required to change one type of rock into another type. Listen to presenter, Bernie Hobbs, explain the forces that transform sedimentary rocks to metamorphic rocks. She visits the Australian Nuclear Science and Technology Organisation (ANSTO) to demonstrate how limestone can be transformed into its matching metamorphic rock. Find out what they do to a limestone sample in the laboratory to cause it to metamorphose into a different rock type.
