Midterm 2 Flashcards
define sediments
inorganic and organic components of the earth’s surface deposited by natural processes
define the different soil horizons
A horizon - zone of accumulation and eluviation encompassing buried A horizons are called paleosols
B horizon - zone of deposition of illuviation
C horizon - parent material/enriched carbonates
list the four types of archaeological context
- primary context - the original context of the find, undisturbed
- secondary context - a find which has had its primary context disturbed
- Systemic context - manufacture, re-use, and discard
- archaeological context - artifacts continue to be affected by human activity and natural processes
define taphonomy
the study of the processes of site disturbance and destruction
What are the 7 relative dating techniques used in archaeology?
- Stratigraphy
- Law of superposition
- seriation
- index fossils
- diagnostic artifacts
- technological change
- age area hypothesis
what are some complications with using relative dating instead of absolute dating techniques?
- mixing of sediments or digging and filling
2. collection of ancient objects or unconformities
list 10 absolute dating techniques and what they can be used on
- historical objects - previously documented objects
- historical documents
- dendrochronology - trees
- radiocarbon C14 - wood, charcoal, plants, bone, organics
- AMS - organics (more accurate than radiocarbon)
- Thermoluminescence - ceramics
- OSL - sediments without organic materials
- KAR - minerals and rocks surrounding fossils
- Uranium-series - limestone and bedrock 50000-1mil
- Fission track - volcanic rock 100000-20mil
discuss the difference between reconnaissance and intensive surveying
reconnaissance - preliminary examination of a survey area
intensive - systematic, detailed field survey that covers an entire area
list 5 ways an archaeologist may find a site
- chance discovery
- asking a local
- documentary records
- oral traditions
- archaeological survey
define the two approaches to archaeological survey
- Non-probabilistic - judgemental, results cannot be used to generalize
- Probabilistic - random sampling, results can be used to generalize through mathematical methods
Define simple simple random sampling
simplest form of probabilistic sampling
define stratified random sampling
define concentrated areas and increase data collection within the areas bound to have more chance of a site
define systematic sampling
choose one unit at random, and select the same unit for each section
define systematic unaligned sampling
combines both simple random sampling and systematic sampling into single strategy
define remote sampling
the science of identifying, observing, interpreting, and measuring objects or surfaces without coming into direct contact with them
