Knowledge and understanding Geological techniques and skills Comments e. A study of fluvial, marine, and aeolian sediments demonstrates these differences. Investigation of textures of sediments from different depositional environments. SP5: Production of full rock description of macro and micro features from hand specimens and unfamiliar field exposures of sedimentary rocks in order to interpret component composition, colour and textures, to identify rock types and to deduce their environment of deposition. SP6: Construction of graphic logs using appropriate scale and symbol sets for unfamiliar geological sequences and exposures to record data relevant to an investigation. SP7: Use of photomicrographs to identify minerals and rock textures of sedimentary rocks in order to identify rock types and to deduce their environment of deposition. Interpretation of maps, photographs and graphic logs showing the following sedimentary features: bedding, cross-bedding, graded bedding, laminations, desiccation features, ripple marks (symmetrical and asymmetrical), sole structures (load/flame, flute cast). Candidates should be aware of the link between process and product in their studies of the stated sedimentary environments: fluvial (rivers, deltas alluvial fans and playa lakes) aeolian (wind dominated e.g. desert dunes) marine (shallow water – lagoon/reef/beach systems) marine (deep water – submarine fan turbidites) Candidates should be able to explain the formation of the stated sedimentary structures.
