Smoking Gun Evidence of an Ancient Earth: GPS Data Confirms
of the following was not used by wegener as evidence of continental drift? are here: home / age of the earth / smoking gun evidence of an ancient earth: gps data confirms radiometric dating smoking gun evidence of an ancient earth: gps data confirms radiometric dating. one way is by dating the magnetic reversals at ridges. led the revival of the continental drift hypothesis and its transformation into plate tectonics. the first method of measurement (x axis) employs radiometric dating of rocks (that are millions of years old) to calculate the average rate of plate motion over that time.

, for your point, we are not merely talking about patterns but dating systems/speed measurements. would radiometric dating, which supposedly is a useless tool for estimating the true age of the earth by yec reckoning, provide near-precise estimates of current plate motions, which are confirmed by a completely unrelated form of measurement? i haven’t read much yec material on this (close to none) but i hardly think they claim that speeds did not decline even to zero relative to the forces they proport caused higher rates of drift. apparent polar wander paths provided the first clear geophysical evidence for continental drift, while marine magnetic anomalies did the same for seafloor spreading. rates of plate motions based on gps and laser methods vs radiometric dating methods for all of the plates of the world.

Rocky Road: Alfred Wegener
in order to collect paleomagnetic data dating beyond 200 mya, scientists turn to magnetite-bearing samples on land to reconstruct the earth's ancient field orientation./geological estimates vs geodetic/gps estimates of continental plate motions. there is also a second reason why some rates don’t match and that is that we may not have accurate radiometric dating for some plates in the world. rather than a coincidence these similar estimates are a powerful testimony to the accuracy plate tectonic models and of the accuracy of radiometric dating techniques. forty years ago, scientists could not have faked the radiometric dating to derive estimates of plate motions that they knew we would find in the future.
Paleomagnetism - Wikipedia
evidence, both reversals and polar wandering data, was instrumental in verifying the theories of continental drift and plate tectonics in the 1960s and 1970s. his principles of physical geology ended with a chapter on continental drift. he pioneered the use of radiometric dating of minerals and was the first earth scientist to grasp the mechanical and thermal implications of mantle convection, which led eventually to the acceptance of plate tectonics.[…] it has also become possible to measure continental drift directly using gps. only reasonable explanation for what we see here is that the radiometric dating methods provide faithful estimates of the real ages of the rocks.
