Perhaps no dating method has the wide range of applicability as does the potassium argon dating method from either consideration of the ranges of ages which can be dated or the availability of suitable material to date. Minerals as young as tens of thousands of years to minerals billions of years old have been successfully dated. Many minerals retain for times of the order of billions of years the daughter, Ar40, and many minerals contain as a component K40 the parent element, potassium being a common element in the earth's crust. As a result, most rock contains at least one mineral which can be successfully dated by the potassium argon method. Even though this method has been applied for over fifteen years, there is as yet no work which summarizes the experimental techniques and the results available. The sixtieth birthday ofW. GENTNER, one of the pioneers in this field of research, is a suitable time to present such a summary.

High Quality Content by WIKIPEDIA articles! Potassium-argon dating or K-Ar dating is a radiometric dating method used in geochronology and archeology. It is based on measurement of the product of the radioactive decay of an isotope of potassium (K), which is a common element found in many materials, such as micas, clay minerals, tephra, and evaporites, into argon. In these materials, the decay product 40Ar is not trapped by the rock while it is liquid (molten), but starts to accumulate when the rock solidifies (recrystallises). Time since recrystallization is calculated by measuring the ratio of the amount of 40Ar accumulated to the amount of 40K remaining. The long half-life of 40K allows the method to be used to calculate the absolute age of samples older than a few thousand years.

Mount Aragats

Mount Aragat is a large andesitic-to-dacitic stratovolcano in NW Armenia about 40 km NW of the capital city of Yerevan. It is the highest point in Armenia, located in the province of Aragatsotn, northwest from Yerevan. Located on its slopes are the Byurakan Observatory and the medieval Amberd Fortress. The observatory is a historically significant facility responsible for a number of important photographic surveys. Mount Aragats is a popular destination for tourists, especially in summer. The 4095-m-high main edifice of Aragats is dissected by glaciers and is of Pliocene-to-Pleistocene age. However, parasitic cones and fissures are located on all sides of the volcano and were the source of large lava flows that descended its lower flanks. Several of these were considered to be of Holocene age, but later Potassium-Argon dating indicated mid- to late-Pleistocene ages. The youngest lower-flank flows have not been precisely dated, but are constrained as occurring between the end of the late-Pleistocene and 3000 BC
