Key Points

The aim is to analyze the Raman spectral characteristics of shocked olivine in ordinary chondrites to identify indicators of shock pressure levels.
Selected 7 ordinary chondrites for analysis including various shock metamorphic features.
Utilized Raman spectroscopy to analyze olivine's main spectral peaks and FWHM across different metamorphic stages.
Compared FWHM values with prior experimental shock data to correlate pressure levels.
The FWHM of DB1 increased from ~12 cm-1 to >20 cm-1, indicating varying shock pressure levels.
A significant positive correlation was found between the FWHM of DB1 and DB2, suggesting similar factors affecting lattice order.
Identified specific FWHM ranges for low, medium, and high shock pressures corresponding to olivine's spectral characteristics.

Study studies shock metamorphism in olivine, suggesting sensitive indicators of impact pressure levels.
