Chapter 1 Flashcards
Survey
map physical remains of human activity
In Situ
materials found originated where they were deposited
Geological Information Systems (GIS)
allow spatial data to be brought together an consolidated
horizontal excavation
excavate broad area in order to expose remains of a single point in time
vertical excavation
excavate a significant depth of deposits in order to expose record of a sequence of occupation
law of superposition
in any undisturbed depositional sequence, each layer of sediment is younger than the layer beneath it
strata
discrete layers in stratigraphic sequence
anthropogenic deposits
deposits from human activity
depositional unit
the material deposited at a site at a particular point in time
provenience
precise context of excavation
datum point
important to control excavation. serves as a reference point for depth measurements at site
wet screening
spraying water onto a sieve to break up sediments and move them through the mesh to make sure artifacts are recovered during excavation
flotation
process used to recover botanical material (wood, seeds) which involves mixing sediments vigorously in water
artifacts
objects that are human manufactured
ecofacts
objects that are remains from biological organisms or results of geological processes
