The paleomagnetism is a powerful tool to date formations that have age not constrained by paleontological, stratigraphical or radiochronological data.
It was applied, on the western border of the Murzuq basin in Algeria (Saharan platform), to the Zarzaïtine formation, attributed to a Middle–Upper Triassic–Lower Jurassic age.
Paleomagnetism is the study of the record of the Earth's magnetic field in rocks, sediment, .
Paleomagnetism relied heavily on new developments in rock magnetism, which in .
The method begins with the careful drawing and description of strata (the geological or archaeological profile).
Of over 4,000 quotations in the set of books this Encyclopedia is based on , only 164 statements are by creationists. Radiocarbon dating is only "consistent" because the large number of C-14 dates which do not agree—are thrown out.—pp. If one or more are incorrect, then C-14 dating will be unreliable.—p. There can never be certainty as to what type of carbon may be present. There can be biological alteration of materials within the soil which can radically affect the dating over a period of time.—p. Geochronology is the science of dating and determining the time sequence of events in the history of the Earth.This web page provides an overview of selected geochronology methods used by USGS scientists.Comparison of the obtained paleomagnetic pole with previous poles from the same geological formation outcropping in another basin and from other Carboniferous to Lower Mesozoic African formations yielded a clearly older age (Late Permian) than expected.That evidences a strong diachronism (at least 40 My) of the deposition of this formation on the Saharan platform.
