In geology lamination is a small scale sequence of fine layers laminae.
Laminated glacimarine sediments form by a variety of processes including suspension settling from turbid overflow plumes turbidity current deposition and contour current activity.
Subglacial deformation of pre existing sediments may also produce laminated deposits in the form of glacitectonite and deformation till.

Although this result is reasonable when only the three sites are compared both values are lower than predicted by existing threshold models with a.
In general the glen eyrie tidalite is similar to other carboniferous tidalites because the laminated sequence directly overlies a coal is well laminated directly above the coal and becomes more bioturbated and possesses more fine scale erosional features beginning several meters above the coal.
At d2 non cohesive sediment and b4 d1 cohesive sediment the critical shear stresses for seabed erosion or resuspension were estimated to be 0 11 and 0 07 0 09 n m 2 respectively.
Lamina that occurs in sedimentary rocks laminae are normally smaller and less pronounced than bedding lamination is often regarded as planar structures one centimetre or less in thickness whereas bedding layers are greater than one centimetre.
