Both of these tend on the average to have wide biostrategraphic limits, meaning that a large spread of ages will be regarded as non-anomalous. If the minerals in the lava did not melt with the lava, one can obtain an age that is too old. One of the best ways to measure farther back in time than tree rings is by using the seasonal variations in polar ice from Greenland and Antarctica. Appearance and Characteristics Argon is considered to be non-toxic. But we know that rocks absorb argon, because correction factors are applied for this when using K-Ar dating. It is possible that the sedimentary layers in the upper Precambrian are also flood deposits See my Geology page. There is a way of dating minerals and pottery that does not rely directly on half-lives.

  1. There are some very serious objections to using the potassium-argon decay family as a radiometric clock. This discovery caused the recognition that argon could form weakly bound compounds, even though it was not the first.

  2. Now, according to Woodmorappe's citations, many lava flows have no such limits at all, and most of them have large limits.

  3. But this would require an atom by atom analysis, which I do not believe is practical. The geochronologist considers the Ca40 of little practical use in radiometric dating since common calcium is such an abundant element and the radiogenic Ca40 has the same atomic mass as common calcium. And such flows often have a large internal scatter of dates, but these dates are not considered as anomalies because of the unrestricted biostratigraphic limit.

  4. Because rhenium and osmium are both siderophilic having an affinity for iron and chalcophilic having an affinity for sulfur , the greatest potential for this method is in studies concerning the origin and age of sulfide ore deposits.

  5. A brand-new coral reef will have essentially no thorium An Explanation of Half-life. The beauty of the Rb-Sr isochron method is that knowledge of the initial Sr isotopic composition is not necessary — it is one of the results obtained.
