A review of the book, Moondust and the Age of the Solar System. Published in Origins v. 20, n. 1.

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.

A collection of short commentaries on scientific papers published in 1991, covering topics such as Permian trees, molecular genetics, epigenetics, inheritance of paternal mtDNA, water and formation of petroleum, water in mantle rocks, impacts, Ordovician volcanism, molecular phylogenies of ratites, termites, cichlids and sabertooths, osteocalcin in dinosaur bones, fossil flowers, origin of life, Precambrian predation, stromatolites, Cambrian Explosion, quality of fossil record, rapid speciation, tree biogeography, Miocene ape, fossil dermopteran, Asian marsupial, dinosaurs, mammal-like reptile.

A review of the book, The Age of the Earth. Presents the standard interpretation of radioisotope data. Published in Origins v. 19, n. 2.

The pipes and dikes in Kodachrome Basin have come from the sedimentary layers below, and raise interesting questions regarding the amount of time involved in their formation. Published in Origins v. 19, n. 1.

Dates calculated from radiocarbon and amino acid racemization show conflict. Analysis of the discrepancies and use of a radiocarbon conversion published earlier, some inferences are drawn regarding the cooling of the earth after the biblical flood. Published in Origins v. 18, n. 2.

Biomolecules decompose rapidly enough they are not expected to last for millions of years. Discovery of biomolecules in fossils is difficult to reconcile with the purported ages of these fossils, and suggests the ages are much younger, as expected in a biblical worldview. Published in Origins v. 18, n. 2.

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.

This is an attempt to develop a methedology for converting carbon-14 ages into real time in a biblical context that fixes the date of the global flood at about 5,000 years ago. A table is provided of sample converted ages. Published in Origins v. 17, n. 2.

A review of the book, Absolute Age Determination. An authoritative description is provided of the methods of age-dating used to estimate the age of the earth. Published in Origins v. 17, n. 2.

The approach outlined in this paper suggests that the radiometric age assigned to the inorganic minerals associated with a fossil is more a reflection of the characteristics of the source of this inorganic material than an indication of the age of the fossil. Published in Origins v. 17, n. 2.

A model of an ice age caused by the Genesis flood is summarized. It proposes solutions to a number of ice-age problems. Published in Origins v. 17, n. 2.

Geologic features of the KT boundary present interesting evidence relating to possible causes of the mass extinction. The widespread existence of the boundary clay has been interpreted as evidence for a worldwide event at the boundary. Published in Origins v. 17, n. 1.

A recent report that the earth's magnetic field must have reversed within a period of several months stimulates interest in the question of multiple magnetic reversals in the geological record and how much time is required for them to occur. Published in Origins v. 16, n. 2.

A review of the book, Principles of Isotope Geology. An authoritative description of radioisotope dating and use of stable isotope ratios. Published in Origins v. 16, n. 1.

A few scientists advocate an expanding earth as an alternative to plate tectonics. Although there are some phenenomina not well explained by plate tectonics, the expanding earth theory is not a satisfactory replacement. Published in Origins v. 16, n. 2.

The layers of sedimentary rock that we see over the surface of the earth usually appear as parallel features that are often spread over wide areas. What does not appear to the casual observer is that between some of these layers major portions of the geologic column are missing. Published in Origins v. 16, n. 2.

The available data on C-14 age profiles indicate that the characteristic relationship is nonlinear in a direction which suggests that the C-14/C-12 ratio was less in the past than it is now. Published in Origins v. 15, n. 1.

This review examines Robert Gentry’s efforts to defend his model of creation built on the study or radiohaloes. Published in Origins v. 15, n. 1.

Some recent radiocarbon dates derived from sources assumed to be geologically very old give dates in the 40,000-year range. These relatively young dates may reflect the concentration of Carbon-14 in the antediluvian atmosphere. Published in Origins v. 15, n. 1.
