It was utilized by the beginning of the 1900s, but took till the early Nineteen Fifties to produce accurate ages of rocks. The nice advantage is that nearly all igneous and metamorphic rocks comprise sufficient U and Pb for this courting. It can be utilized on powdered entire rocks, mineral concentrates (isotope dilution technique) or single grains (SHRIMP technique). This relatively new technique was developed so as to achieve extra accurate dates than those obtained from the potassium-argon technique. The older method required two samples for relationship and will produce imprecise dates if the argon was not absolutely extracted. This newer methodology converts a stable form of potassium (potassium-39) into argon-39.
