We liked the photo of him looking rugged after climbing a mountain in Borneo and the fact he'd worked in Switzerland for six years, which is where I was brought up. For example, dates may be accepted even when there is evidence of weathering, and rejected when there is not. But he didn't say when the correct value for the branching ratio began to be used. In areas where tremendous tectonic activity has taken place, highly discordant values for the ages are obtained.

This could cause trouble for Rb-Sr dating. We talked and laughed for hours - I smiled all the way home and he even told his flatmate that he'd met his future wife! I also believe that the evidence indicates that the earth has recently undergone a violent catastrophe. There may be evidence of heating, but the date may be accepted, and there may be no such evidence, but a hypothetical heating event is assumed anyway. In a similar way, argon could enter the rock from the air or from surrounding rocks and make it look older. Japan[ edit ] There is a type of courtship called Omiai in which parents hire a matchmaker to give resumes and pictures to potential mates for their approval, leading to a formal meeting with parents and matchmaker attending.

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. This verifies what I said about almost all of the dates used to define correct ages for geologic periods being K-Ar dates. Ground-water and erosional water movements could produce this effect naturally. I also read of a case where a rock was K-Ar dated at 50 million years, and still susceptible to absorbing argon from the air. Potassium is found to be very mobile under leaching conditions. Perhaps the earth was made from older pre-existing matter, or perhaps decay rates were briefly faster for some reason. And if we recall that most radiometric dating is done of igneous bodies, one sees that the percentage of anomalies is meaningless.

Each radioactive element has a half-life, which tells how long it takes for half of the element to decay. Under favourable circumstances the isochron method may be helpful, but tests by other techniques may be required. This statement is made so often as evidence for the reliability of radiometric dating, that the simple evidence that it has no meaning, is astounding to me. Geologists often say that the percentage of anomalies is low. The percentage of published dates that are considered as anomalous has little bearing on the question. They noted, 'The solubility of Ar in the minerals is surprisingly high'.

Here is another quote from Woodmorappe about isochrons, since some people think that mixing scenarios or other age-altering scenarios are unlikely: Thus it may take experiments lasting 50 or years at low temperatures to detect the effects of this kind of diffusion of argon, which however could be significantly increasing the K-Ar ages of minerals over long time periods. It is composed of little glass beads that come from volcanic ash. Gerling et al called attention to some chlorites yielding K-Ar dates of 7 to 15 b. Dalrymple goes to great lengths to explain this away, but I think this figure is very telling, and find his explanations unconvincing. It seems reasonable to me that the large radiometric ages are simply a consequence of mixing, and not related to ages at all, at least not necessarily the ages of the rocks themselves. It does not answer the overall question. Sara McCorquodale suggests that women meeting strangers on dates meet initially in busy public places, share details of upcoming dates with friends or family so they know where they'll be and who they'll be with, avoid revealing one's surname or address, and conducting searches on them on the Internet prior to the date. In general, if lava was heated after the initial flow, it can yield an age that is too young.
