Arch. Final Section I Flashcards
exposure of remains via controlled digging
excavation
what is the goal of control in excavation?
to reconstruct everything and see how they fit together in space
what does excavation tell us? (2) (HW)
1) how are sites created?
2) what are they composed of?
layers represent activities and deposit (cultural and natural) from different time periods
STRATA
sequence of strata built up in layers
stratigraphy
in an undisturbed stratigraphic sequence each layer (strata) is younger than the layer beneath
law of superposition
problems with the law of superposition (2) (WM)
1) wall can be built on top of older strata
2) making sense of what you’re digging during excavation is most challenging
types of controlled excavation
1) grids (horizontal)
2) datum points (vertical)
what do horizontal excavation rep?
activities at any point in time
what does vertical excavations rep?
a single fixed point that all depth points are taken from (how the site has changed)
goals of excavation
1) identify strata
2) recover remains
3) reconstruct horizontal (same) and vertical (through time) relationships
excavation techniques
1) digging (axes, trowels, picks)
2) brushing
3) screening- put dirt through screens and find artifacts
4) flotation (stones will sink and bones and artifacts will float)
excavation strategies
1) horizontal excavation (remains from the same period)
2) vertical excavation (remains from successive time periods)
excavated materials (3)
1) artifacts
2) features
3) ecofacts
evidence of human manufacture
artifacts
non-portable cultural items (buildings, monuments, burials)
features
remains of biological organisms (human bones, animals, seeds, wood)
ecofacts
what type of material is a mammoth foot bone that is craved into a flute and why?
an artifact because it was modified
documentation techinques (4) (NPDD)
1) notes and forms
2) photographs
3) drawing and maps
4) digitization
what is the goal of documentation?
rconstruction of remains in context
the significance of remains interpreted based on where they were deposited (provenience) and what they were deposited with (association)
context
chronology based on stratragraphic sequences. not sure of the actual date.
relative dating
relative frequencies through time
seriation
dating contexts and artifacts in calendar years via scientific tests
absolute chronology
