Aim: To examine one thin section (high resolution scan) of unconsolidated sediment from a cold
environment,
and determine sedimentary, deformational and post-depositional processes in order to inform
(palaeo)environmental reconstruction by:
a) Describing textural features (e.g. grain size, grain shape, grain orientation, matrix texture, matrix
density etc.)
b) Describing structural features (e.g. voids, rotation/compression/slump, planar, abrasion, sediment
mixing, porewater, plasmic fabric, post-depositional etc.)
c) Relating the above textural/structural features to processes (e.g. sedimentation, ductile/brittle
deformation, porewater expulsion etc.) and then relating these specific processes to environments of
deposition (e.g. glaciofluvial, glaciolacustrine, glaciomarine, subglacial, iceberg scour, periglacial etc.)
d) Considering advantages and limitations of micromorphology as a technique.
