Q

Why Classify Artifacts?

A
  1. Organizing Data into Manageable Units
  2. Describing Types
    Knowing what the artifacts are
  3. Identifying Relationships between types
  4. Studying Assemblage Variability in the Archaeological Record
    Organizes framework for synthesizing data

Q

Why do we Reconstruct Reduction Sequences?

A

If lithic debitage can be matched with the stage of the reduction sequence in which it was produced, we can reconstruction the spatial organization of tool manufacturing, use and reworking

Q

Stages of Lithic Reduction

A
  1. Acquire raw material
  2. Primary/early stage reduction
    1) Core preparation
    2) Initial reduction
  3. Secondary reduction
    1) Trimming, thinning and shaping
    2) Preparation of preforms/tool blanks
  4. Tertiary reduction
    1) Final finishing/shaping of tool
    2) Resharpening/modification of too

Q

Primary/Early Stage Flakes

A

Flakes from earliest stages of breaking open raw material and preparing cores
Often 50-100% dorsal cortex
Large in size
Limited dorsal and platform scarring

16
Q

Secondary Stage Flakes

A

Shaping and thinning of flakes to create tool blanks
Lots of variation
Medium in size/thickness
Shaping – broad; thinning - long
Platforms still fairly simple, more dorsal scarring (generally)
No cortex

17
Q

Late/Tertiary Stage Flakes

A

Final stages of tool production – sharpening and resharpening of stone tools
Small
Multifaceted platform, angled lip
Complex scarring on platform; can be complex on dorsal surface but depends on size
Resharpening flakes have use wear on platform

18
Q

Lithic Raw Materials

A

Better understand the knapping process (including acquisition and stone selection), settlement patterns, seasonal migration, cultural contact, trade networks, economics, and ethnicity
The best raw materials for chipped stone tools are fine grained (micro or crypto crystalline)
Identify raw materials through macroscopic and/or microscopic assessment of characteristics such as color, luster, texture, translucency

19
Q

Obsidian

A

Extrusive, igneous, fast cooling rock
Volcanic glass
Comes from a number of sources – most common in Alberta are Obsidian Cliff (Wymoning) and Bear Gulch (Idaho), but there are also sources in Oregon (Glass Buttes), British Columbia (Mt. Edziza) and Alaska, among others.
Can be sourced to a specific volcano using XRF analysis
An obsidian flake is sharper than surgical steel

20
Q

Massive Quartz

A

Coarsely crystalline quartz silicate
Large grain/crystal size
Fractures along facets
Multiple sources
Secondary alluvial deposits and glacial tills
Quarries in southern BC and Montana
Banff National Park

21
Q

Knife River Flint

A

Chert silicate formed when silica replaced organic material in a North Dakota peat deposit 30-60 million years ago
Not actually flint (brown chalcedony)
Can have visible plant microfossils
Distinctive white patina with blueish tinge
Fluoresces faint orange under black light
Quarried from secondary deposits in North Dakota’s Dunn and Mercer counties
Widely used on the Plains

22
Q

Swan River Chert

A

Chert silicate which ranges from gray to white and looks like curdled milk
Often heat treated – turns pink
Distinct vugs (irregularly shaped holes) and microfossiol inclusions
Outcrops in Swan River Valley, west-central Manitoba
Secondary deposits in gravels in alluvial and glacial deposits in southern Saskatchewan and Alberta, at least as far west as Medicine Hat

23
Q

Montana Cherts

A

Chert silicate
Most are yellow/brown in color with black dendrites/inclusions
Avon and Madison Chert are exceptions – white/grey and creamy
Highly variable – come from a number of quarry sources in Montana, most near Helena (a few further west)

24
Q

Etherington Chert

A

Chert silicate
aWhite to light gray, purples, mottled
Blocky, not as fine grained
Nodules in the Livingstone range of southern Alberta

25
Q

Pebble Chert

A

Pebble sized chert silicate nodules
All sorts of colors
Outcrops in Alberta (Neutral Hills) and Montana
Also found in secondary alluvial and glacial deposits
Often subject to bipolar reduction

26
Q

Chalcedony

A

Silicate composed of quartz and moganite
Translucent/slightly translucent
Many colors
Cryptocrystalline
In secondary deposits all over the place

27
Q

Petrified Wood

A

Wood fossilized by replacement of organic material with silica
Cellular structure of the wood often still visible
Clear banding which tends to platy layers
Fractures follow wood grain which produces tabular flakes and stepped terminations
Yellows, browns, dark red
Relatively common in secondary deposits on the Northwestern Plains

28
Q

Silicified Siltstone

A

Siltstone with high amounts of silica bound through metamorphosis, which bind the particles together
Larger grain size than cherts - can see individual grains with naked eye or hand lens
Lots of variability, found in secondary deposits all over
There are a few identifiable types (i.e., Banff Chert, which is actually a silicified siltstone)

29
Q

Porcellanite

A

Mixture of silty clay and carbonaceous deposits silicified with a large amount of silica
Can occur above and below burned coal seams
Ceramic like
Less hard and dense than chert
Medium to dark grey or red, black
Large outcrops of high-quality porcellanite occur in southern Montana

30
Q

Quartzite

A

Metamorphosed sandstone
Individual sand grands are firmly cemented together and clearly visible
Course to very course grained
Commonly used lithic raw material on the North Plains
Lots of variability in color, grain size
