As I understand it, in that case it is by dating the age of the materials the wood in question was buried in. The minerals are dated using luminescence dating. That tells you when those particles were last exposed to sunlight.
- facialwipe 3y agoI don’t trust any dating technique that requires the combustion of material.
- defrost 3y agoWell, this dating relates to when quartz and|or feldspar crystal were last in strong sunlight .. it's not "combustion" as such. The changes wrought in the material by sun exposure and subsequent changes over time in the dark are strongly repeatable. https://en.wikipedia.org/wiki/Luminescence_dating https://en.wikipedia.org/wiki/Luminescence_dating
- pests 3y ago> Most luminescence dating methods rely on the assumption that the mineral grains were sufficiently "bleached" at the time of the event being dated. For example, in quartz a short daylight exposure in the range of 1–100 seconds before burial is sufficient to effectively “reset” the OSL dating clock Very interesting
