The argon-40 content of the atmosphere and the age of the earth

摘要: Abstract Applying the theory that continents havo been formed by addition of volcanic material from depth during geologic time, and assuming this released all its radiogenic argon-40 while it was in molten state, an age earth has calculated content earth's atmosphere. Using current estimates potassium crustal rocks, volume continents, atmosphere, we find atmosphere could have way if were 5,300 million years old. This value is reasonable agreement with other universe. It therefore concluded a explanation for derivation atmospheric argon.
