Micromorphology Report

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.
