KBS Tuff shows the flaws of radiometric dating Talk. Origins From CreationWiki, the encyclopedia of creation science Jump to: Origins is a response to a rebuttal of a creationist claim published by Talk. Origins Archive under the title Index to Creationist Claims. It is significant because hominid fossils and artifacts were found in and under it, so its age gives a minimum age of the fossils. Various attempts to date it have yielded a wide range of different results, from 0. The dating of the KBS Tuff exposes the fallacies of radiometric dating. And in practice, it is impossible to be sure one has selected uncontaminated samples. The pigs took it all. Creation 17 3 June:

Forbidden Archeology of the Early and Middle Pleistocene: Morwood concluded toolmaking hominids arrived by boat. Boatmaking and sailing are normally associated with anatomically modern humans. Anatomically modern human femurs of the same age from Java offer corroborating evidence.
Ages obtained from several tuffs by the 40Ar/39Ar method suggest an approxmate match between the observed magnetozones and the geomagnetic polarity time scale; however, the palaeomagnetic results are also compatible with a younger chronology suggested by conventional K-Ar dating of the KBS Tuff.??

Lubenow A popular myth is that radioactive dating methods confirm the geologic time-scale and the concept of human evolution.
The methods appear so impressive that many Christians accept them as evidence that the earth is very old. He immediately organized an expedition to search for hominid fossils. Skull is modern in appearance, but was originally estimated by Richard Leakey to be about 2. Seeking to unravel the geology of the area, she discovered a layer of volcanic ash or tuff that became known as the Kay Behrensmeyer Site the KBS Tuff. If the KBS Tuff were anywhere else, no one would give it a second thought.

Radiometric dating utilizes the decay rates of certain radioactive atoms to date rocks or artifacts. Uniformitarian geologists consider this form of dating strong evidence that the Earth is billions of years old. “The Case of the KBS Tuff.” In The Age of the Earth, Randy S. Berg, ed.

Early Acheulean With the change from Olduwan to Acheulean technique, hominins got more of a return for a given output of energy and could do more. The chief technological development was the edge of the handax. More and better flakes meant better use of carcasses and therefore a need for fewer carcasses, less hunting, etc.
Moreover, the increased number of flakes available made ranging farther from the source of the stone possible and gave more staying power to the hunt. Stratigraphy Koobi Fora is underlain by Pliocene basalts and filled with nearly meters of Pliocene- Pleistocene sediments , dating from about four-million to one-million years ago. The members reflect changing environments in the Turkana Basin, from lake and delta ones during Burgi Member times to rivers and floodplains in Okote Member times.
The stratigraphy of the Koobi Fora Formation is one of the best studied and calibrated in East Africa. In addition, the unique fusion between geochronology and mammal evolutionary studies has made the Koobi Fora Formation a standard for all of Pliocene-Pleistocene Africa.

Doesn’t mean that he has no idea of what he’s talking about now does it Click to expand No, it means he wrote something down that he wants people to take at face value without providing anything to back it up. I could easily claim that 8 out of 10 creationists have never been to school. Unfortunately, it’s a meaningless statement at best without something to qualify it.
variations in the estimates by fission track dating of the age of the KB Tuff ‘S Storze. r & Wagner choose to use this objectively the message from the history of work on the KBS Tuff is completely to the contrary. The final and definitive study using zircon FTD, by Gleadow (), gave a result which has a precision of + 5% (2.
For example, potassium changes into the gas argon at the rate of one half, every 1, million years. For example, if one can determine the relative amounts of potassium and Argon and then apply the 1, m. Radiometric dating is based upon several assumptions, all of which must be true for the method to work. First, the average rate of decay must be known and must have remained constant since the rock was formed.
Second, the proportion of daughter product in the rocks at the time the rocks were formed must be known. If there was unaccounted-for daughter product in the rock to begin with, the rocks will have a built-in appearance of age. No sand gets into or out of an hourglass; the sand merely falls from the top to the bottom. The same must be true of the parent and daughter elements in tested rocks, if they are to keep time like an hourglass.

The Oldowan was not automatically accepted by all researchers as evidence of the earliest human culture in Africa. In , Wayland had discovered another lithic industry, in the stone assemblages collected from the terraces of the Kafu River in Uganda. This culture, named Kafuan, consisted of fractured cobbles which were very archaic looking [ 27 ]. Although the characterization of the Kafuan and its sub-stages was based on dubious criteria such as the roundness or the elongation of pieces collected from river terraces with high-energy deposits [ 26 ], the fact remains that the term Kafuan became established in the archaeological literature of the s— s e.

Have you ever wondered how scientists “know” the age of the Earth? Cook, a physical chemist now in his eighties, is a world expert on high explosives and his textbook on explosives for mining is still a classic work of reference. Professors of metallurgy do not usually stir up trouble in the academic world, but what I had read in his geology book was more explosive than any text on TNT.
In his preface Cook wrote: Who on earth had prevented Dr. Cook from publishing his paper? And what could a metallurgy professor have to say that was so heretical that someone wanted to prevent its publication? I found that his book contained scientific evidence and reasoned argument which showed that something was terribly wrong with the orthodox scientific view of methods of dating.
The most widely used methods, such as uranium-lead and potassium-argon, had been found to be seriously flawed, not merely in practice but in principle. In addition, the methods yielded dates so discordant as to make them unreliable. Cook showed for example that if you used the uranium-decay method on the rocks of the crust you got the conventionally accepted age of over four thousand million years.
The birds were singing, the flowers were blooming, and the paleo-anthropologist were digging, when lo and behold, a fossil was found in northern Kenya near Kanapoi. And not just any old fossil mind you, but a hominid fossil. And elbow to be exact. The lower end of a left arm bone.

Wishing to establish the age of the primitive tools found by Kay Behrensmeyer, Leakey sends samples of the tuff to Jack Miller, a geophysicist at Cambridge University. Jack Miller along with his partner Frank Fitch duly dates the tuff and determines that it is somewhere between and million years old. Obviously they said, the ash had been deposited when rivers or streams had washed it down from highlands into a floodplain picking up minerals from older deposits in the process.
Never mind that there was no evidence that the deposit had been deposited by rivers or streams, and never mind that they could not identify any exposed Triassic outcrops from which those older minerals could have come from. It was enough to know that the results were not in line with evolutionary expectations. When the second set of samples came in for testing, samples from the same supposedly contaminated volcanic tuff that had previously dated to to million years, Fitch and Miller again tested the samples and this time came up with a date of just 2.
