Rapid Identification of Cryptic Exsolution Lamellae Using BEX

Many minerals develop exsolution lamellae as complete miscibility is not possible during cooling. Analysing the composition of exsolution structures offers valuable insights into the cooling history of rocks. However, lamellae without significant BSE contrast may remain undetected during typical analytical approaches. Using BEX, the combination of high-speed X-ray mapping and BSE imaging within a single detector can identify cryptic exsolution lamellae. Identifying these features can greatly impact the understanding of a rock’s thermodynamic history.
