We know that the internal structure of zircon is typically obtained by polishing and capturing cathodoluminescence (CL) or backscattered electron (BSE) images. This method usually allows us to understand the internal structure of zircon, such as the core-rim structure. However, this is only 2D and can only reveal the surface structure exposed by polishing. So I am wondering if there is a technology that can help us determine whether there are more complex zonations beneath the surface?
Depending on resolution required, either X-ray Computed Tomography or Synchotron (more detailed, more difficult) can help you with that. Or, you can also use destructive method Atom Probe Tomography, that will also gather the chemical composition at the atomic scale
