WebLamination is often regarded as planar structures one centimetre or less in thickness, whereas bedding layers are greater than one centimetre. [1] However, structures from several millimetres to many centimetres have been described as laminae. [2] A single sedimentary rock can have both laminae and beds. Description [ edit] WebBedding and lamination are defined by layers of different composition or texture, typically reflecting environmental change during deposition; Fissility is a fabric characteristic of …
