The new and the old dates fall on either side of the accepted date of 28 to 30,000 years ago for Neanderthal extinction.
Since the dates established by carbon-14 for the paintings at Lascaux and Altamira occurred after the the remnant Neanderthals became extinct, it follows the cave paintings were created by our ancestors.
Lloyd Anderson, far right, takes home-schooled children on a tour of the land around Mount St.
Helens, pointing out geologic structures formed by the volcano’s eruption in 1980 that young-Earth creationists say support their beliefs.“Look! ” Lloyd Anderson springs ahead of the small group of visitors he has been leading through Gifford Pinchot National Forest.
Since its introduction in 1992, use of the technique has spread rapidly. The OCR Web site (com/dsfrink/ocr/ocrpage.htm) lists domestic clients in 33 states as well as clients working in Argentina, Australia, Bermuda, Canada, the Czech Republic, Somalia, and South Korea. Results from the Ball and Walkley-Black procedures produced abnormal ratios during my analyses of hearth feature samples (predominantly containing charcoal) from local Native American sites.
The method is said to be applicable from the present to at least 10,000 years ago, and its precision is stated to a constant 3 percent of the age (Frink 1997: 3). Braziunas 1998b High-precision Radiocarbon Age Calibration for Terrestrial and Marine Samples. Although these procedures do not yield the same values for organic carbon, the results obtained from analyses of agricultural topsoils form a constant ratio (Hesse 1971).
Which is: The Earth is only a few thousand years old, and what happened here in 1980 proves it. Anderson and his wife, Doris, are the founders of the Mount St.
The snow-capped volcano dazzles against a crystal blue sky, its peak obliterated 25 years ago in an eruption that left it looking like a dish of vanilla ice cream whose top has been scooped off by an eager child.They are: (1) the C14 concentration in a specimen at its time of death; (2) the decay rate of C14; (3) the current C14 concentration in the specimen being “dated”; and (4) if anything else has affected the specimen’s C14 content. The curved line represents the declining amount of C14 atoms over time due to radioactive decay.Note: only the third of those four necessary facts can be measured, the other three must be estimated, assumed, or extrapolated. During each half-life (~5,730 years), about half of the remaining C14 atoms in a specimen are expected to decay.The rapid spread of acceptance of OCR dating by archaeologists concerns us for three reasons: (1) No description of the method has yet appeared in a peer-reviewed journal. Variability in the ratio was found to be related to soil texture and depth (factors that affect the rate of oxygen diffusion), temperature and moisture regimes (factors that control the rate of biological processes), and soil p H and concentration of organic carbon (factors that contribute to the viability and speciation of biological populations in the soil).(Papers reporting the results of OCR dating have appeared in several peer-reviewed journals, including Science (Saunders et al. (2) Neither Frink's published papers nor the OCR Web site provide a scientifically acceptable demonstration of the accuracy and precision of OCR dating. The degree of effect for both p H and percent organic carbon was found to be nonlinear, and best modeled using the square-root of these values.
