WebNov 23, 2024 · The entire analysis was based on 61 core plug samples supported by P and S wave velocity, petrography analysis, and porosity. Petrographic analysis shows predominant lithofacies in Minahaki Formation are grainstone, while Tomori Formation was dominated by muddy carbonate (wackestone to packstone). Robert J. Dunham published his classification system for limestone in 1962. The original Dunham classification system was developed in order to provide convenient depositional-texture based class names that focus attention on the textural properties that are most significant for interpreting the depositional environment of the rocks.

The presence of any primary carbonate mud precludes a classification of grainstone. A study of the use of carbonate classification systems by Lokier and Al Junaibi (2016) highlighted that the most common source of confusion in the classification of grainstone was to misidentify fine-grained internal micrite, generated by in-situ processes, as clay–silt grade sediment - thus resulting in the misidentification of grainstone as packstone.
