Water From Volcanoes

"It has been estimated that seventy volcanoes the size of Mexico's Paricutin producing 0.001 cubic mile of water per year for 4.5 billion years of earth's history could account for the 315 cubic miles of water in the oceans today. There are now approximately 600 active volcanoes and about 10,000 dormant ones. Six hundred volcanoes comparable to Paricutin could account for the present oceans in approximately 0.5 billion years."

Uranium In the Oceans

"Uranium salts presently appear to be accumulating in the oceans at about 100 times the rate of their loss. It is estimated that 60,000,000,000 grams of uranium is added to the oceans annually. Under uniformitarian rules, the total concentration of uranium salts of the oceans (estimated at less than 1E+17 grams) could be accumulated in less than one million years.

Helium In the Atmosphere

"The atmospheric content of helium-4 (the most abundant isotope of helium) has accumulated from the radioactive decay of uranium and thorium in the earth's crust and oceans, from nuclear reactions caused by cosmic rays, and from the sun. If the present rate of accumulation has been constant throughout four billion years of the earth's history, there should be thirty times as much helium in our present atmosphere as is presently there."

Meteoric Dust In Strata

"One estimate of meteoric dust settling to earth places it at 14.3 million tons annually. If this rate has been constant throughout five billion years of geologic history, one might expect over fifty feet of meteorite dust to have settled all over the surface of the earth. ... The average meteorite contains about three hundred times more nickel than the average earth rock."

Meteorites In Strata

"No meteorites have been found in the geological column."

Lava In The Crust

"It has been estimated that four volcanoes spewing lava at the rate observed for Paricutin and continuing for five billion years could almost account for the volume of the continental crusts. The Colombian plateau of northwestern United States (covering 200,000 square miles) was produced by a gigantic lava flow several thousands of feet deep. The Canadian shield and other extensive lava flows indicate that volcanic activity has indeed followed an accelerated tempo in the past. The fact that only a small percentage of crystal rocks are recognizably lavas...."

Pressure In Oil Reservoirs

"Some geologist find it difficult to understand how the great pressures found in some oil wells could be retained over millions of years."

Human Population Dynamics

"If humanity is really about 2.5 million years old (as claimed by Dr. Louis Leakey), creationist calculate from conservative population estimates (2.4 children per family, average generation and life span of forty-three years) that the world population would have grown from a single family to 10 to the 2700th power of people over one million years. The present world population is about 2x10 to the 9th power, an infinitesimal part of the 10 to the 2700th power."

Radiocarbon In Atmosphere

"It now appears that the C14 decay rate in living organisms is about 30 per cent less than its production rate in the upper atmosphere. Since the amount of C14 is now increasing in the atmosphere, it may be assumed that the quantity of C14 was even lower in the past than at the present. This condition would lead to abnormally low C14/C12 ratios for the older fossils. Such a fossil would be interpreted as being much older than it really is. ... Creationists argue that since C14 has not yet reached its equilibrium rate, the age of the atmosphere must be less than 20,000 years old."

Dr. Stansfield's "Answer":

"By this methodology, creationists stand guilty of the "crime" they ascribe to evolutionists, namely uniformitarianism. All the above methods for dating the age of the earth, its various strata, and its fossils are questionable, because the rates are likely to have fluctuated widely over earth history. A method that appears to have much greater reliability for determining absolute ages of rocks is that of radiometric dating."

But He Acknowledges:

"If we assume that (1) a rock contained no Pb206 when it was formed, (2) all Pb206 now in the rock was produced by radioactive decay of U238, (3) the rate of decay has been constant, (4) there has been no differential leaching by water of either element, and (5) no U238 has been transported into the rock from another source, then we might expect our estimate of age to be fairly accurate. Each assumption is a potential variable, the magnitude of which can seldom be ascertained. In cases where the daughter product is a gas, as in the decay of potassium (K40) to the gas argon (Ar 40) it is essential that none of the gas escapes from the rock over long periods of time.

Stanfield's Conclusion:

It is obvious that radiometric techniques may not be the absolute dating methods that they are claimed to be. Age estimates on a given geological stratum by different radiometric methods are often quite different (sometimes by hundreds of millions of years). There is no absolutely reliable long-term radiological 'clock."' SCIENCE OF EVOLUTION, pp. 80-84.
