Faults with radio carbon dating gorgeous men intimidating
Pretty obvious that the dike came after the rocks it cuts through, right?
With absolute age dating, you get a real age in actual years.
Look for “absolute” ages such as cornerstones, dates carved into fresh concrete, or dates stamped on manhole covers.
Absolute age dating: Have students work alone or in pairs to find an article or paper that uses radiometric age dating.
The most relevant one for my work has been U-Pb on zircon.
U-Pb is a very reliable way of getting the age and history of zircon crystals, which are a common and extremely resilient mineral found in igneous systems.
The method works best with material more than 1 My, with precisions in the ±1 My range (I've mostly been working on material in the 1.8 to 3.0 Gy range, ±1 My is a mind blowing degree of precision in this context).
Radiometric dating is any method of age determination which is based on radioactive decay.
