Potassium-argon Dating - YouTube

But in most cases where the system has been disturbed, there simply is no date given. The important point to note is that, rather than giving wrong age dates, this method simply does not give a date if the system has been disturbed. This is also true of a number of other igneous rock dating methods, as we will describe below. Figure 3.

The Radiometric Dating Game - Computer Science

Potassium-40 is especially important in potassium–argon (K–Ar) dating. Argon is a gas that does not ordinarily combine with other elements. So, when a mineral forms – whether from molten rock, or from substances dissolved in water – it will be initially argon-free, even if there is some argon in the liquid.

Over the last 78 years numerous determinations have been made of the total 40 K decay half-life, obtained by direct counting experiments and by comparing radioisotope ages derived from more than one dating method applied to the same rocks or minerals. The determinations since 1997 have converged with close agreement toward the total 40 K decay half-life value of 1.2524±0.0064Byr.

Potassium carbonate (K 2 CO 3) is a deliquescent (usually damp or wet) white salt that readily dissolves in water to form a strongly alkaline solution. First identified in 1742 by Antonio Campanella, it is the primary component of potash and the more refined "pearlash" or "salts of tartar." Pearlash has been used to produce soap, glass, and china..
