Test #2 Flashcards
Describe the category of Discard with the deposition stage.
Artifacts that are no longer useful and are placed into the AC.
The goal of excavation is to intercept and isolate _________ and ________ _________.
floors and occupational surfaces
What is disturbance in the deposition stage?
The changing or altering of an archaeological context by the effect(s) of an unrelated activity at a later time. Examples include dam building, farming, and heavy construction, as well as noncultural activities such as freeze-thaw cycles, landslides, and simple erosion. Disturbance is also the nonscientific removal of an artifact from its archaeological context.
ex: agriculture and plowing
What is washing material to find artifacts?
Wet screen
A ________ is the starting point on a grid.
Datum
Dr. Widmer likes to start away from the origin (0,0) to handle data errors and other stuff like that.
Define Heavy floatation
soil that sinks to the bottom of the water. A 1 mm mesh is used to strain out artifacts.
Define the Cache category of deposition.
Useful artifacts are placed into the AC.
ex: time capsule, offerings
What is Magnetometry within remote sensing?
Use of a large-scale metal detector. Can be used on land or water.
What is midden?
area of Secondary Refuse
What does it mean when an artifact is in the Archeological Context?
The artifact is no longer associated with ongoing behavior.
“forgotten about”
Fill does not have ______________.
multiple levels
A _____ is when there is a change in color, smell, sound, or presents artifacts occurs within a zone.
Layer
What are isotopes?
atoms that are varied in atomic weight. Usually used for bones
What is Sub Surface Sampling?
Small excavations that are dug into the ground to find artifacts. ex: Post hole excavations
_______ are inside structures.
Rooms
Which deposit type is least important?
Fill
What is Sonar within remote sensing?
Sound waves that are bounced off bottom water to look for shipwrecks and sunken artifacts.
What are phytoliths?
plant skeleton parts
What is the Secondary Use category of the Reuse stage?
The artifact is the same but the function changes.
ex: tire swing
What is Lidar within remote sensing?
Light pulses
What does it mean when an artifact is in situ?
The artifact is in its original location and has never been moved since it was put into the archeological context.
Can be used with point provenience.
Describe Reclamation with the deposition stage.
Artifacts are removed from the AC and put back into the systemic context. Deals with deposition but not a part of the deposition.
ex: lab / museum
Define the systemic context of manufacture and give examples?
Artifacts created from _new_ material
The second stage of behavioral processes, in which raw materials are modified to produce artifacts
ex: creating hides for clothing
Define the systemic context of deposition and give examples
The placing artifacts into the archeological context.
The process by which artifacts enter the archeological context.
“forgot about” or “lost”
ex: Burial, Garbage Dump
Define the Loss category of Deposition.
Useful artifacts are unintentionally placed in the AC.
What is the process of removing sediments from artifacts known as?
Excavation
What is stratification?
The layering of natural sediments at a site.
What is a provenience lot?
A defined spatial area, in either two dimensions (for surface data) or three dimensions (for excavated data), used as a minimal unit for provenience determination and recording.
Define the systemic context of procurement and give examples?
obtaining the raw materials for the artifact
ex: collecting of plant foods
Name 5 Deposit Types.
- Burial
- Feature
- Collapse
- Fill
- In situ soil
What is Ground Penetrating Radar within remote sensing?
Uses radio waves to penetrate the ground and bounce back to form images
What is the Vertical Datum?
An imaginary number for elevation that is used as a reference. does not have to be correct. Keeps the elevation in sync within the grid.
Each layer that has artifacts is called a _____.
lot
