Dating of non carbonaceous materials
The dating process is always designed to try to extract the carbon from a sample which is most representative of the original organism.
The ICR (Institute for Creation Research) recently spent eight years on a project known as RATE (Radioisotopes and the Age of The Earth).Apart from scatter of the U-Pb, Th-Pb, Rb-Sr, and Ar-Ar ages, no systematic pattern was found in the Allende isochron and model ages similar to the systematic pattern of isochron ages found in Precambrian rock units during the RATE project. If such evidence in earth rocks is applied to meteorites, then Allende seems to have no apparent evidence in it of past accelerated radioisotope decay. The Allende CV3 carbonaceous chondrite meteorite, which fell to earth in Mexico February 8, 1969, is one of the most-studied meteorites. Many radioisotope dating studies in the last 40 years have used the K-Ar, Ar-Ar, Rb-Sr, Sm-Nd, U-Th-Pb, Lu-Hf, Mn-Cr, W-Hf, Al-Mg, and I-Xe methods to yield an abundance of isochron and model ages for this meteorite from chondrules, Ca-Al inclusions, whole-rock samples, and matrix, mineral, and other fractions, all of which components are described.
