Only rarely does a creationist actually find an incorrect radiometric result (Austin 1996; Rugg and Austin 1998) that has not already been revealed and discussed in the scientific literature.The creationist approach of focusing on examples where radiometric dating yields incorrect results is a curious one for two reasons.The Chilean volcano, 760 miles south of the capital, Santiago, may be settling down after spewing ash and pumice, creating mudflows and causing floods that displaced a town of 4,000 people. When Rick La Husen treks to Chile later this month, it will be the fourth USGS-sponsored trip in response to the Chaiten eruption.
First, it provides no evidence whatsoever to support their claim that the earth is very young.
If the earth were only 6000–10 000 years old, then surely there should be some scientific evidence to confirm that hypothesis; yet the creationists have produced not a shred of it so far.
The belief that radiodating methods give absolute measurements of time is widespread as a result of scientific popularization in journals, conferences, and the media.
In fact, due to the difficulties in applying the experimental method to events in the past, all chronometers based on natural or artificial nuclear disintegration need a calibration.
Where excess argon is a problem, accurate, reliable dates typically can be obtained using harlequin2, 2001.
Geochronology and Thermochronology by the 40Ar/39Ar Method.
This calibration supposes a great number of basic assumptions concerning initial conditions.
The choice of these initial conditions affects the results.
Morris cited other examples of anomalous dates produced by excess argon and falsely claimed that it is a universal problem for K-Ar dating.
The problem is not universal, as the majority of minerals and rocks dated by K-Ar do not contain the excess argon.
VANCOUVER -- Geological "spiders," packed with instruments to monitor the heaves, sighs and belches of Mount St. Two of the contraptions are headed to Chaiten, a volcano in Chile that began erupting in 2008 after about 9,000 years of dormancy. Geological Survey, which fielded a team of scientists on the South American mountain in January, worked with their Chilean counterparts to decide if it was time to summon the spiders. Helen's epochal 1980 eruption, is one of the latest examples of survey volcanologists offering help around the world.
