FAQ
Frequently Asked Questions
No. Carbon-14 dating is one specific technique within geochronology, used for relatively recent organic materials. Geochronology encompasses many other methods (like uranium-lead, potassium-argon) for dating much older rocks.
Biostratigraphy uses fossil assemblages to order rocks relative to each other (relative dating). Geochronology provides absolute numerical ages in years.
Yes. It requires sophisticated laboratory equipment like mass spectrometers to measure isotopic ratios.
Not all rocks are datable. The rock must contain suitable minerals with trace radioactive elements (like zircons) or have been exposed to datable events like volcanic eruptions.
