Document Summary
Esci 2211 principles of sedimentology and stratigraphy. Observations: objective characteristics (physically present indisputable) subjective characteristics (opinion, prejudices) avoid when possible unless actually observed. Classification: arrangement of material in classes or categories arrangement always subjective e. g. classification within periodic table: semi-metal/metalloid or not?, posttransitional metal or not depends on research/purpose, country/background. When trying to understand/explain/interpret how seds (sediment and sedimentary. Sediment: particulate matter that is available for moving, or is being moved, or has been moved by a physical process (fluid flow and/or under the influence of gravity) Lithology: physical and chemical properties of sediments and sedimentary rock: qualitative and quantitative (measurable) properties of seds. 2 basic types of particle: cements: particles that (partly) enclose/interlock with others, grains: particles that are not interlocking. Sediments: grains and little cement (because cement locks grains together therefore they are unable to move, ie. are loose)
