Many Christians have been led to distrust radiometric dating and are completely unaware of the great number of laboratory measurements that have shown these methods to be consistent.

Because the grains are angular, loess will often stand in banks for many years without slumping.

Thus sometimes, dating is dependent on paleontologist scholarship to provide the historical context against which an artifact's relevance and age can be assessed, through stylistic comparison with cave paintings and engravings at other archeological sites.

At present, a large variety of fossils, tools and artifacts are being studied by paleoanthropologists and other Stone Age scholars, in order to fix their date of origin.

Wiens has a Ph D in Physics, with a minor in Geology.His Ph D thesis was on isotope ratios in meteorites, including surface exposure dating.This soil has a characteristic called vertical cleavage which makes it easily excavated to form cave dwellings, a popular method of making human habitations in some parts of China. In several areas of the world, loess ridges have formed that are aligned with the prevailing winds during the last glacial maximum.These are called "paha ridges" in America and "greda ridges" in Europe.Later excavations in the 1980s established Malakunanja as the oldest dated site in Australia.
