The 25 pages that link to K–Ar dating, each with the reason it gives.

• Radiocarbon datingCompared with: It dates volcanic materials and geological events rather than the organic remains targeted by radiocarbon dating.

• Radiometric datingBroader topic: It is widely used to date volcanic rocks and geological events across millions of years.

• PotassiumRelated: Radioactive potassium provides a clock for dating volcanic rocks and geological events.

• Homo erectusRelated: It has helped date volcanic layers associated with important Homo erectus fossils.

• GeochronologyBroader topic: It dates volcanic materials that help bracket fossils and archaeological sites.

• Uranium–lead datingCompared with: Unlike uranium–lead dating, it measures a gas daughter that can escape when rocks are heated.

• Archaeological datingBroader topic: It can date volcanic layers associated with very ancient archaeological evidence.

• Olduvai GorgeRelated: It helped establish absolute ages for Olduvai’s volcanic layers and associated finds.

• Electron captureRelated: Potassium-40 decays to argon-40 partly through electron capture.

• Potassium-40Broader topic: It uses potassium-40’s decay to estimate the ages of potassium-bearing rocks.

• U–Pb datingCompared with: Unlike U–Pb dating, it commonly uses potassium-bearing minerals and volcanic rocks.

• Argon–argon datingCompared with: Argon–argon measures both isotopes in one sample, avoiding separate potassium analysis.

• Mary LeakeyRelated: Dating volcanic layers helped establish ages for Olduvai’s fossil-bearing deposits.

• Uranium–thorium datingCompared with: It is suited to volcanic rocks, not the young carbonate archives targeted here.

• ArgonRelated: Radioactive decay within rocks produces argon that can record their formation age.

• OrthoclaseRelated: Potassium-bearing feldspar can be analyzed, though argon loss and alteration complicate dating.

• Rubidium–strontium datingCompared with: Unlike rubidium–strontium dating, it commonly dates argon retention after cooling.

• Uranium-series datingCompared with: It is suited to volcanic rocks and generally much older ages than uranium-series dating.

• Absolute datingBroader topic: It dates volcanic rocks and can constrain the ages of fossil-bearing deposits.

• Thermoluminescence datingCompared with: It dates mineral formation or cooling over geological timescales, not an artifact's last firing.

• Rubidium-87Compared with: Unlike rubidium–strontium dating, it relies on argon retention and is especially useful for volcanic rocks.

• Middle AwashRelated: Volcanic rocks in the region provide material for dating fossil-bearing deposits.

• BiotiteRelated: Biotite can retain argon after cooling, providing a record of its thermal history.

• AluniteRelated: Alunite has been dated to constrain the timing of mineralizing fluids.

• Primordial nuclideBroader topic: Primordial potassium-40 provides a clock for dating rocks and volcanic events.
