Age
The ages of tektites from the four strewnfields have been determined using radiometric dating methods. The age of moldavites, a type of tektite found in Czech Republic, was determined to be 14 million years, which agrees well with the age determined for the Nördlinger Ries crater (a few hundred kilometers away in Germany) by radiometric dating of Suevite (an impact breccia found at the crater). Similar agreements exist between tektites from the North American strewnfield and the Chesapeake Bay impact crater and between tektites from the Ivory Coast strewnfield and the Lake Bosumtwi-Crater. Ages of tektites have usually been determined by either the K-Ar method, fission-track dating, the Ar-Ar technique, or combination of these techniques.

Famous quotes containing the word age:
“When superstition is allowed to perform the task of old age in dulling the human temperament, we can say goodbye to all excellence in poetry, in painting, and in music.”
—Denis Diderot (1713–1784)
“Need I explain to the inhabitants of England, for whom I chiefly write, how extreme are those sufferings, and how great the costliness of that old age which is unable in any degree to supply its own wants? Such old age should not, we Britannulists maintain, be allowed to be.”
—Anthony Trollope (1815–1882)
“No such sermons have come to us here out of England, in late years, as those of this preacher,—sermons to kings, and sermons to peasants, and sermons to all intermediate classes. It is in vain that John Bull, or any of his cousins, turns a deaf ear, and pretends not to hear them: nature will not soon be weary of repeating them. There are words less obviously true, more for the ages to hear, perhaps, but none so impossible for this age not to hear.”
—Henry David Thoreau (1817–1862)
