dealing with rejection in dating - Dating a rock

(Welles, Samuel Paul, “Paleontology,” In some cases darwinists have recognized circularity as a typical problem in evolutionary models and worked to avoid it.“To test this idea, we matched earliest Cambrian records of carbon isotope variability from Siberia, Mongolia, and China with a Moroccan record constrained by five radiometric ages from interbedded volcanic ashes.E., “Pragmatism Versus Materialism in Stratigraphy,” , vol. 47.) “One might imagine that direct methods [radiometric dating] of measuring time would make obsolete all of the previous means of estimating age, but these new ‘absolute’ measurements are used more as a supplement to traditional methods [index fossils] than as a substitute.

Scales of stratigraphic disorder may be from millimeters to many meters.

Stratigraphic disorder is produced by the physical or biogenic mixing of fossiliferous sediments, and the reworking of older, previously deposited hard parts into younger sediments.

Apart from very ‘modern’ examples, which are really archaeology, I can think of no cases of radioactive decay being used to date fossils.” (Ager, Derek V., “Fossil Frustrations,” , vol. 425.) “The larger part of the Phanerozoic time scale…relies on a construction where stages are first scaled ‘geologically’ with biostratigraphic compositing techniques, and then stretched in linear time using key radiometric dates. E., “Pragmatism Versus Materialism in Stratigraphy,”, vol. 53) “A great deal has changed, however, and contemporary geologists and paleontologists now generally accept catastrophe as a ‘way of life’ although they may avoid the word catastrophe.

In fact, many geologists now see rare, short-lived events as being the principal contributors to geologic sequences….

The periods of relative quiet contribute only a small part of the record.

…The charge that the construction of the geologic scale involves circularity has a certain amount of validity….

It is almost the first thing I teach my first-year students. al., : Biostratigraphy: Time Scales from Graphic and Quantitative Methods,” , 2004, p. The rocks do date the fossils, but the fossils date the rocks more accurately.

Ever since William Smith at the beginning of the 19th century, fossils have been and still are the best and most accurate method of dating and correlating the rocks in which they occur. 49.) “Are the authorities maintaining, on the one hand, that evolution is documented by geology and, on the other that geology is documented by evolution? Stratigraphy cannot avoid this kind of reasoning, if it insists on using only temporal concepts, because circularity is inherent in the derivation of time scales.” (O’Rourke, J.

This failure leaves the method vulnerable to circularity.” (Stanley, Steven M., Warron O.
