The LP82 carbonate thin section is classified as wackestone, consistent with a matrix-supported fabric containing more than ten percent allochems under the Embry and Klovan framework.

Geological interpretation and evidential boundary
The LP82 carbonate thin section is classified as wackestone, consistent with a matrix-supported fabric containing more than ten percent allochems under the Embry and Klovan framework. Reported grain sizes of 5–15 mm at 40× magnification are physically suspect and likely reflect a unit or calibration transcription error; the scale must be corrected before textural inference. Modal percentages should total transparently and distinguish skeletal grains, pisoids, quartz, microspar, spar cement and pore space. The wackestone fabric supports relatively low-energy deposition or protected conditions, but recrystallisation and cementation may obscure primary texture. It does not independently prove reef growth, and should be integrated with field framework evidence and fossil taphonomy.
