Lithic Analysis
Preserve for oldest amount of time
Lithic technology
- Reductive technology- reduce volume of big stone to prodice object we want
- 1)flaked stone
- 2) Ground stone
Ground Stone- made by abrasion
- Shape stone by pecking, grinding, and polishing
- Can cut stone with this
- With another stone, grind a grove in the stone on both sides. Able to crack the stone afterwards
and get two stones
- Will be extremely smooth. The other stone was fine, result is very shiny and smooth resulting
stone
Flake Stone
- Made by flint knapping- shapes the stone
- By percussion, snapping the stone
- Small flakes are removed
Core- raw materials mass from which material has been removed
Flake- piece of stone detached from a core through the application of force
Blade- flake that is at least twice as long as it is wide. Very difficult to do
Tool- implements created through flaking or grinding
Core tools- tools produced by removing flakes from core to produce sharp edges of core itself
Flake or blade tools- tools made from the flakes themselves
Debitage- waste aterial fro the productio process, thigs they did’t use
How to differentiate from natural stones
- Conchoidal fracture- when people hit two stones together, it creates force. Surface is not flat, a
ball of force.
Flake attributes
- Side that is flat- ventral side (usually inside the core)- see ball of force
- Dorsal side (outside of core)- can see imprints of flakes coming off. Flake scars
- Distal end is quite sharp

Reductive technology- reduce volume of big stone to prodice object we want. With another stone, grind a grove in the stone on both sides. Able to crack the stone afterwards and get two stones. The other stone was fine, result is very shiny and smooth resulting stone. Made by flint knapping- shapes the stone. Core- raw materials mass from which material has been removed. Flake- piece of stone detached from a core through the application of force. Blade- flake that is at least twice as long as it is wide. Core tools- tools produced by removing flakes from core to produce sharp edges of core itself. Flake or blade tools- tools made from the flakes themselves.
