Please clarify your question! What do you mean by "type change" in the context of rock structure?

Do you mean:

* Rock cycle transformations? (Igneous, Sedimentary, Metamorphic)

* Changes in mineral composition?

* Deformation due to tectonic forces?

* Changes in rock type due to weathering and erosion?

Once you provide more context, I can help you understand how rock structures change during different processes.
