Arch. MIDTERM #1 Flashcards
challenges of archaeological preservation (4) (PNGH)
1) processes affect remains
2) needs to be put back together (like a puzzle)
3) Geological and environmental factors
4) human activity
what are examples of geologic and environmental factors and are they intentional or unintentional?
earthquakes, rain, erosion, flooding, dry etc.
unintentioanal
what are some challenges when geologic & environmental factors affect preservation?
1) organic materials can decay
2) artifacts can get washed away
what are some examples of human activity affecting preservation? (PFHL) (4)
unintentional
1) people leave or die
2) farming (plows over archaeological sites)
3) human settlement
4) looting (intentional)
identifying and mapping physical remains of human activity
survey (recovery method)
ways to perform survey (2) (WT)
1) walk around grounds
2) talking to people in the area
what are some challenges of survey (2) (tv)
1) terrain
2) vegitation (covered by dense foliage with insects)
any loci of past human activity
site
culturally or geographically defined cluster of sites
region
survey techniques (2) (GR)
1) GPS
2) Remote Sensings
types of remote sensings (survey technique) (2) (AL)

2) 3D topographical map
Example of lidar

what is an advantage of survey?
non-destructive
what can survey reveal? (2) (IS)
1) identify relationships b/t sites and b/t sites and landscape
2) surface artifacts
exposure of remains via controlled digging
excavation
what is the goal of controlled digging?
to reconstruct everything and see how they fit together in space
how are sites created?
through STRATA
layers represent activities and deposit (cultural & 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
are the younger strata on top or bottom?
top
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 (verticle)
what are the goals of excavation? (3) (IRR)
1) identify STRATA
2) recover remains
3) reconstruct horizontal (same time) and vertical (through time) relationships
what type of time does horizontal and vertical represent?
horrizontal (info from same time) and vertical (through time)
excavation techniques (4) (DBSF)
1) digging (axes, trowels, picks)
2) brushing
3) screening
4) flotation
expose remains from the SAME period
horizontal excavation
expose a sequence from successive time periods
vertical excavation
excavated materials found (3) (AFE)
1) artifacts
2) features
3) ecofacts
what does excavated artifacts tell us?
evidence of human manufacture
non-portable cultural items (building, monuments, burials)
features
remains of biological organisms (human bodies, animals, seeds, wood)
ecofacts
documentation techniques (4) (NPDD)
1) notes and forms
2) photographs
3) drawings & maps
4) digitization
what is the goal of documentation?
reconstruction of remains in Context
the significance of remains interpreted based on where they deposited (provenience) and what they were deposited with (association)
context
a list to draw upon an inventory of types of artifacts found by archaeologists in a particular archaeological context
typology
how do most classifications of articles begin?
by defining major categories of objects
chronology based on stratigraphic sequences (not sure of the actual date) places assemblage in a temporal sequence not directly linked to calendar dates
relative dating
relative frequencies through time
seriation
dating contexts and artifacts in calendar years via scientific tests
absolute chronology
an absolute dating technique. measures how long it has been since something organic died (must have once been alive). measurement of the rate of decay of the radioactive (unstable) carbon isotope C14 from dead plant/animal remains
radiocarbon dating
measures absolute age by counting rings in tree-cross sections. it correlates patterns in a long term sequence (much more accuratae)
dendochronology (tree ring dating)
a type of dating that measures the rate of decay of isotope potassium 40 into argon 40
potassium- argon dating
what is the half-life of potassium-argon dating?
1.25 billion years
what does potassium-argon dating measure?
volcanic rocks, lava and ash
what is potassium-argon dating food for?
fossil contexts
what is the difference between artifacts and features which were both created intentionally by humans?
non-portable (such as hearths or walls)
when is argon dating not usueful?
in areas with limited volcanic activity
analyzing human remains
skeletal analysis
how is age assessed in skeletal analysis?
tooth erruption & bone fusion for individuals under 25
what affects skeletal assesment?
health
what is the best indicator of biological sex during skeletal analysis?
in the pelvis (compromise b/t upright walking and giving birth).
findings during skeletal analysis (5) (cdapd)
1) cause of death
2) disease, malnutrition, injuries
3) activities
4) place of birth (chemical composition of bones)
5) diet (using chemical techniques)
types of artifact analysis findings (3) (spe)
1) stone tools (use wear, source material)
2) potterty (from, techniques, designs, clay source)
3) ecofacts (past environment & diets)
a type of artifact analysis that analyzes microscopic residue from flotation and soil samples
microarchaeology
what radically alters inerpretation during artifact analysis?
microarchaeology
how did the site at Ashkelon, Israel alter the interpretation?
it wasn’t a residence but an animal pen
other examples of microarchaeolgy (where the interpretation is altered)
1) flotation- lint suggests clay cylinders = loom weights
2) soil chemistry: altar wasn’t for burning incense but pouring libations
measures the light (stable) elements of hydrogen, carbon, nitrogen, oxygen and sulfur in organic samples to determine composition (drinking water) (expensive)
stable isotope analysis
what is stable isotope analysis used for?
human and animal bone, teeth and hair to determine diet and origins
precursors of interpretation
1) age of discovery: 15th and 17th centuries
2) industrial revolution- late 18th and 19th centuries (western world began to change)
intellectual developments that scientists discovered during precursors of intepretations (3) (OOD)
1) order the living world
2) observe change
3) develop theory about cultural and biological evolution

1) hypothesis testing
2) scientific method
Lewis Binford (Processualism)
searched for universal laws and processes
what did Lewis Binford find culture to be?
adaption to the environment
what type of approach did Lewis Binford use?

an outsider’s view of culture
etic approach
when did post processualism occur?
1980s- 1990s
backlash against processualism
post processualism
why was post processualism a backlash against processualism?
1) positivism was too objective
2) archaeological excavation is not replicable
what type of view did post processualism have?
archaeology more like history than science (remains in a text)
what type of perspective does post processualism have?
Emic
the insiders view of their own culture
emic approach
what is the archaeological theory today?
anthropologists struggle to find balance between scientific approaches to explain culture and interpretive approaches to understanding its meaning (humanist)
if you need to expose remains of activities from a single period across a broad area at a site which type of excavation would you use?
horizontal
if you need to recover information from multiple strata as well as expose activities areas within in a single strata or time period what type of excavation would you use?
vertical and horizontal
if you need to expose several consecutive time period and strata at a site what type of excavation would you use?
vertical
what is the most important goal of excavation?
to reconstruct horizontal and vertical relationships at sites and recover remains in context
a technique for classifying features of small things found at an archaeological site
flotation
emphasizes the similarities between history and archaeology and suggests archaeologists take an emic approach to understanding culture
