The presence of corals indicates a shallower depositional environment, allowing coral growth (Schlager, 2003; Wu et al. 40). The wackestone is composed dominantly of lime mud and various fossil fragments (trilobites, bivalves, and bra- chiopods; Fig. Most recently, this definition has been clarified as a carbonate-dominated rock in which the carbonate mud (<63 μm). The higher porosity in mud-supported sediments is caused by the needle shape of small aragonite crystals that make up the carbonate mud, and the decrease in permeability is caused by the small pore size found between mud-sized. The Formation consists of light to dark gray limestone with shale intercalations.

Due to the proprietary nature of many geoscience data, the data size is limited to what was provided in the SEG ML contest, which is a relatively small data set compared to what treasure troves the AI pioneers in the tech sector can dispose of. This is part of the Dunham classification of carbonate rocks. 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.
