Archaeology Hub
Time & Dating
How archaeologists place stone artifacts, quarrying, and building traditions into time—so identification and interpretation become more accurate.
What this hub covers
Time is one of the strongest clues in archaeology. When you know when a stone object was made, used, repaired, or deposited, you can narrow down likely raw materials, manufacturing methods, trade routes, and even common lookalikes. This hub gathers the dating approaches most often used around stone—especially where geology and archaeology overlap.
For a quick, culture-and-period overview, see the main Timeline page. The pages below go deeper into how dates are established and how those dates affect stone identification.

- Timeline (period guide and quick reference)
Why dating matters for stone
- Materials shift over time (new quarries, new trade routes, new preferences).
- Techniques leave time-stamped traces (tool marks, finishes, standard forms).
- Deposits mix—dating helps separate old stone from later disturbance.
- Lookalikes exist—time narrows the plausible options.
Subpages in this hub
These are shorter, focused pages. For now they’re placeholders with brief descriptions; each will expand into a full guide as the archaeology library grows.
Relative dating
- Stratigraphy & context — reading layers, cuts, fills, and redeposited stone.
- Typology & style — how forms, finishes, and tool marks change through time.
- Seriation — ordering assemblages when absolute dates are scarce.
Absolute dating
- Radiocarbon (C-14) & stone contexts — dating associated organics, not the stone itself.
- OSL/TL (luminescence) — dating last exposure to light/heat for sediments and heated materials near stone.
- U-series & carbonates — where carbonate crusts, speleothems, and related deposits help bracket time.
Stone-specific approaches
- Obsidian hydration — hydration rims as a time-sensitive signal (with local calibration).
- Surface exposure & weathering — what patina, rounding, and micro-erosion can (and can’t) tell you.
- Building phases & repair sequences — reading masonry joins, mortar changes, and stone replacement.
How this connects to the Timeline
Use Timeline when you need a fast period reference. Use this hub when you need to justify a date (or a date range) based on context, method, and material behavior—especially when stone identification depends on narrowing the time window.
