Can carbon 14 be used for dating lava flows explain

) is an earth science concerned with the solid Earth, the rocks of which it is composed, and the processes by which they change over time.

Geology can also refer generally to the study of the solid features of any terrestrial planet (such as the geology of the Moon or Mars).

Steve Austin and his associates at the Institute for Creation 'Research' (ICR) collected a dacite sample from Mt. Helens, Washington State, USA, which probably erupted in 1986 AD. then ineffectively separated the sample into several mineral and glass 'fractions', submitted the dacite and its 'fractions' for potassium 40-argon 40 (K-Ar) dating, and subsequently used the bogus results to inappropriately attack the K-Ar method.

Considering that the half-life of potassium-40 (40K) is fairly long (1,250 million years, Mc Dougall and Harrison, 1999, p.

Geology also plays a role in geotechnical engineering and is a major academic discipline.

The majority of research in geology is associated with the study of rock, as rock provides the primary record of the majority of the geologic history of the Earth.

Austin's paper or at any scholarly criticism of it, your eyes will quickly glaze over from the extraordinary detail and intricacy.

So I thought this would be a great place to point Skeptoid's skeptical eye, and see how much of the chaff we can cut through to see what the bare facts of the case really are.

93)Cambridge, Massachusetts, USA, performed the K-Ar dating for Austin et al. However, when they did, their website clearly stated in a footnote that their equipment could not accurately date rocks that are younger than about 2 million years old ("We cannot analyze samples expected to be younger than 2 M. Geologic studies of active tectonism are greatly aided by definition and time calibration of local stratigraphic sequences.Because all dating techniques may be subject to considerable error, reliability should be assessed by stratigraphic consistency between results of different dating methods or of the same method.Geologic assessment of active tectonism depends on two key measures: the age and the amount of deformation of a given stratigraphic unit.The amount of deformation can normally be measured with greater accuracy than the age.
