Over time, so-called “anomalous fading” reduces the observed signal strength of feldspar samples dated using this method. For 10 points each:
[10h] Name this dating method that is often applied to quartz through the single-aliquot regenerative-dose, or SAR, protocol. Techniques using this method date samples by dividing the equivalent dose by the dose rate.
ANSWER: luminescence dating [accept more specific answers such as thermoluminescence or radioluminescence or optically-stimulated luminescence; prompt on OSL or TT-OSL or IRSL or TL or RL or ISL by asking “What does the L stand for?”]
[10e] Optically stimulated luminescence is often used to date deposits of this sediment. This unconsolidated sediment forms namesake “fans” when it deposits onto floodplains.
ANSWER: alluvium [or alluvial deposit; accept alluvial fans; prompt on colluvium; reject “diluvium”]
[10m] Most alluvium comes from parent material of this geologic period. The Younger Dryas was a stadial that occurred during this period, while the clathrate gun hypothesis sought to explain interstadials during this period.
ANSWER: Quaternary Period [prompt on Q]
