Mudstone depositional environment
The oxygen levels in the depositional environment correlate roughly with the energy levels (high-energy = high oxygen); high-energy water is well-agitated ... which have been transported and deposited by physical processes (e.g. sandstone, mudstone). The grainsize depends almost entirely on the water energy (high-energy => large grainsize). ...History Original classification. 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.
