A discontinuity (e.g., a bedding plane) generally is a weak plane compared to the rock matrix and has prominently lower strength and higher compressibility. Where bedding surfaces occur as cross-sections, e.g., in a 2-dimensional vertical cliff face of horizontal strata, are often referred to as bedding contacts. Within conformable successions, each bedding surface acted as the depositional surface for the accumulation of younger sediment.
