Radioisotope Age, Part II: Genesis and Time: What Radiometric Dating Tells Us

Radiometric dating is an interpretive science. The complex chemical and physical processes taking place within Earth's mantle and crust are neither completely known nor understood. This is especially true when the radioactive isotope parameters are considered.

Radioisotope Age, Part I

Various examples adequately establish that a radioisotope age does not necessarily have a real-time significance. A relationship of a radioisotope age with real-time must be based on an interpretation.

Footprints in the Sands of Time

Coconino Sandstone research has demonstrated how catastrophists can use their theory to develop specific hypotheses about a geologic feature (the Coconino Sandstone), and successfully carry out scientific research to test that hypothesis. This is one criteria that science used to determine the scientific value of any theory.

Coal: How Did It Originate?

The catastrophic burial of plant debris and its subsequent change to coal is not accepted by most coal geologists. However, the dominant "peat bog" theory presents problems that have remained unanswered for more than a hundred years. A Flood model for the formation of coal answers some of these problems and provides a scientifically reasonable explanation for the origin of the vast quantities of coal that exist worldwide.

The Puzzle of the Petrified Trees

It is unwarranted to assume a priori, as in the past that all upright petrified trees had grown in the place where they are now found. The transport of trees and their deposition in an erect stance is not as unlikely or as rare as might be expected. Upright fossil trees within the geological column are compatible with a Flood model. Actually, when all factors are considered, a catastrophe involving water and many floating trees is a more satisfactory explanation for their origin.

The Santana Formation

The unnatural mixture and the rapid stratigraphic shifts of fauna seem to require catastrophic water transport into the area. The large geographic extent precludes a local event. Creationists suggest that a world-wide flood could produce results as seen in the Santana Formation and is a better explanatory model.

Some Questions about Geochronology

The geochronological time scale of thousands of millions of years is based mainly on radiometric dating. On the other hand, some other time-dependent processes change at rates which challenge generally accepted geochronology. Published in Origins v. 13, n. 2.
