dating  


      n   any of several techniques, such as radioactive dating, dendrochronology, or varve dating, for establishing the age of rocks, palaeontological or archaeological specimens, etc.  


carbon dating  
      n      short for       radiocarbon dating  
carbon-14 dating  
      n      another name for       radiocarbon dating  
computer dating  
      n   the use of computers by dating agencies to match their clients  
cross-dating  
      n     (Archaeol)   a method of dating objects, remains, etc., by comparison and correlation with other sites and levels  
dating agency  
      n   an agency that provides introductions to people seeking a companion with similar interests  
fission-track dating  
      n   the dating of samples of minerals by comparing the tracks in them by fission fragments of the uranium nuclei they contain, before and after irradiation by neutrons  
potassium-argon dating  
      n   a technique for determining the age of minerals based on the occurrence in natural potassium of a small fixed amount of radioisotope 40K that decays to the stable argon isotope 40Ar with a half-life of 1.28x109 years. Measurement of the ratio of these isotopes thus gives the age of the mineral  
   Compare       radiocarbon dating       rubidium-strontium dating  
radioactive dating  
      n      another term for       radiometric dating  
radiocarbon dating  
      n   a technique for determining the age of organic materials, such as wood, based on their content of the radioisotope 14C acquired from the atmosphere when they formed part of a living plant. The 14C decays to the nitrogen isotope 14N with a half-life of 5730 years. Measurement of the amount of radioactive carbon remaining in the material thus gives an estimate of its age,   (Also called)    carbon-14 dating  
radiometric dating  
      n   any method of dating material based on the decay of its constituent radioactive atoms, such as potassium-argon dating or rubidium-strontium dating,   (Also called)    radioactive dating  
rubidium-strontium dating  
      n   a technique for determining the age of minerals based on the occurrence in natural rubidium of a fixed amount of the radioisotope 87Rb which decays to the stable strontium isotope 87Sr with a half-life of 5 x 1011 years. Measurement of the ratio of these isotopes thus gives the age of a mineral, for ages of up to about 4 x 109 years
