Short summary
Our research found that the cookeite crystallized within a closed space (e.g., crystal-rich inclusion, CI, in pegmatites) at relatively high PT conditions might bear distinct and high-purity Raman signals. As a result, this type of cookeite is unusual and provides an indicator of cookeite crystallized in the closed spaces of a primary inclusion (e.g., CI), beneficial for recognizing the primary nature of the CIs in pegmatites and understanding the formation mechanisms of CIs and pegmatites.
