Meteorites date the earth with a 4.55 ± 0.07 Ga Pb-Pb isochron called the geochron. They appear to consistently yield 4.55-4.57 Ga radioisotope ages, adding to the uniformitarians’ confidence in the radioisotope dating methods. About 82% of all meteorite falls are chondrites, stony meteorites containing chondrules. Nearly 94% of chondrites are ordinary (O) chondrites, which are subdivided into H, L, and LL chondrites based on their iron contents. Enstatite (E) chondrites comprise only 1.4% of the chondrites. Many radioisotope dating studies in the last 45 years have used the K-Ar, Ar-Ar, Rb-Sr, Sm-Nd, U-Th-Pb, Re-Os, U-Th/He, Mn-Cr, Hf-W, and I-Xe methods to yield an abundance of isochron and model ages for these meteorites from whole-rock samples, and mineral and other fractions. Such age data for fifteen O and E chondrites were tabulated and plotted on frequency versus age histogram diagrams. They generally cluster, strongly in some of these chondrites, at 4.55–4.57 Ga, dominated by Pb-Pb and U-Pb isochron and model ages, testimony to that technique’s supremacy as the uniformitarians’ ultimate, most reliable dating tool. These ages are confirmed by Ar-Ar, Rb-Sr, Re-Os, and Sm-Nd isochron ages, but there is also scatter of the U-Pb, Th-Pb, Rb-Sr, and Ar-Ar model ages, in some cases possibly due to thermal disturbance. No pattern was found in these meteorites’ isochron ages similar to the systematic patterns of isochron ages found in Precambrian rock units during the RATE project, so there is no evidence of past accelerated radioisotope decay having occurred in these chondrites. This is not as expected, because if accelerated radioisotope decay did occur on the earth, then it could be argued every atom in the universe would be similarly affected at the same time. Otherwise, asteroids and the meteorites derived from them are regarded as “primordial material” left over from the formation of the solar system, which is compatible with the Hebrew text of Genesis that could suggest God made “primordial material” on Day One of the Creation Week, from which He made the non-earth portion of the solar system on Day Four. Thus today’s measured radioisotope compositions of these O and E chondrites may reflect a geochemical signature of that “primordial material,” which included atoms of all elemental isotopes. So if some of the daughter isotopes were already in these O and E chondrites when they were formed, then the 4.55-4.57 Ga “ages” for the Richardton (H5), St. Marguerite (H4), Bardwell (L5), Bjurbole (L4), and St. Séverin (LL6) ordinary chondrite meteorites obtained by Pb-Pb and U-Pb isochron and model age dating are likely not their true real-time ages, which according to the biblical paradigm is only about 6,000 real-time years. The results of further studies of more radioisotope ages data for many more other meteorites should further elucidate these interim suggestions.
