WebThin-bedded, graded skeletal packstone to fine-grained grainstone The following rock sample shows a transitional set of graded beds showing a lower packstone type bed with larger skeletal pieces and a fine-grained matrix. This is overlain by a coarser-grained, skeletal grainstone which shows a higher degree of sorting and physical breakage.

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. WebDetermining the fracture toughness of rock materials is a challenging, costly, and time-consuming task, as fabricating a sharp crack in rock specimens will lead to failure of the specimen, and preparing specimens for determining the rock fracture packers backup quarterback
