Which processes can put OLDER objects into YOUNGER deposits?
Hints
- Residuality has many mechanisms: digging, erosion, reuse.
- The reverse direction is what no process can achieve.
Show the answer
- A. Digging a pit through ancient layers and backfilling it
- B. Reusing centuries-old timber in a new building
- D. Rivers eroding an old site and redepositing its artifacts
Why
Residuality has many engines, pits, rivers, reuse. What no process can do is the reverse: place a genuinely future object into a truly sealed deposit. That one-way street is the logic TPQ dating drives on.
