The cave is one of the most celebrated examples of Paleolithic art.
Isochron dating requires a fourth measurement to be taken, which is the amount of a different isotope of the same element as the daughter product of radioactive decay.
(For brevity's sake, hereafter I will refer to the parent isotope as ).
The equation is the one which describes radioactive decay: If one of these assumptions has been violated, the simple computation above yields an incorrect age.
Note that the mere existence of these assumptions do not render the simpler dating methods entirely useless.
Some of the traces of artistic activity found include finger-painted lines, fingerprints and possibly prints of the lower part of the palm.
Excavations and restorations at the site have been led by V. Zhitenev, head of Moscow State University's South Ural archeological expedition and leading researcher for the Kapova and the nearby Ignatievskaya caves.
Some of the artistic techniques, the placing of the images in the Kapova cave as well as what other human evidence remains, has shown these underground sanctuaries have a connection to those found in the Franco-Canrabrian region—modern day southeastern France.
The Kapova cave is located in Bashkiria, a southwestern Russian province near the country’s border with Kazakhstan.
The X-axis of the graph is the ratio of in a closed system over time.
It is not easily explained, in the general case, in any other way.
Its composition would be represented as a single point on the isochron plot: Note that the above is somewhat simplified.
