Fission track dating — is a radiometric dating technique based on analyses of the damage trails, or tracks, left by fission fragments in certain uranium bearing minerals and glasses. Uranium 238 undergoes spontaneous fission decay at a known rate. The fragments emitted … Wikipedia
Fission Track Dating — (Spaltspurendatierung) ist eine radiometrische Methode zur Datierung der Abkühlgeschichte von Gesteinen anhand von bestimmten, in den Gesteinen enthaltenen Mineralen (Thermochronologie). Spaltspuren sind mikrometergroße Defektlinien (engl.… … Deutsch Wikipedia
fission-track dating — Method of determining the age of a mineral that utilizes the damage done by the spontaneous fission of uranium 238, the most abundant isotope of uranium. The fission results in radiation damage, or fission tracks, that can be made visible by… … Universalium
fis|sion-track dating — «FIHSH uhn TRAK», a method of determining age of rocks and other geological formations by counting the characteristic tracks left by spontaneous fission of uranium 238 during the lifetime of each sample. The number of tracks is proportional to… … Useful english dictionary
dating — I In geology and archaeology, the process of determining an object s or event s place within a chronological scheme. Scientists may use either relative dating, in which items are sequenced on the basis of stratigraphic clues (see stratigraphy) or … Universalium
Radiometric dating — (often called radioactive dating) is a technique used to date materials such as rocks, usually based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.[1]… … Wikipedia
Nuclear fission product — Nuclear fission products are the atomic fragments left after a large atomic nucleus fissions. Typically, a large nucleus like that of uranium fissions by splitting into two smaller nuclei, along with a few neutrons and a large release of energy… … Wikipedia
Spontaneous fission — (SF) is a form of radioactive decay characteristic of very heavy isotopes, and is theoretically possible for any atomic nucleus whose mass is greater than or equal to 100 u (elements near ruthenium). In practice, however, spontaneous fission is… … Wikipedia
