Age Determination of Young Rocks and Artifacts. Physical and by Günther A. Wagner

By Günther A. Wagner

The Quaternary, which spans nearly the final 2 million years, is characterised by means of dramatic environmental alterations, generally known as the "ice age". in this interval, guy along with his manifold cultures developed. makes an attempt at relationship those occasions as correctly as attainable have made nice development. The large spectrum of actual and chemical courting tools, now to be had for courting human artifacts and Quaternary rocks, is turning into more and more tough to understand. during this publication many of the chronometric strategies are comprehensively and intelligibly handled. by way of quite a few case experiences, taken from archaeology and Quaternary geology, the aptitude and quandary of those ideas are validated. The ebook is meant quite often for scientists and scholars of those fields, however the layman can also locate its worthwhile.

Example text

Metals are hardly datable. In the case of stone tools the situation has considerably improved during recent years. More promising are all kind of objects made of burned clay, although the attainable accuracy of measurement does not always satisfy chronological demands. The term age needs to be specified. Concerning inorganic artifacts one has to clearly distinguish between the age of formation of the material, the age of manufacture, the age of burial, and if necessary the age of other events, such as heating or bleaching.

Since humid and warm environmental conditions enhance chemical reaction rates, zones with intensive chemical weathering represent important paleoclimatic indicators. During the Quaternary, the interglacials and to a lesser degree the interstadials represent such periods of increased chemical weathering. Early Man's activities are often associated with periods of improved climate. The age of fossil weathering phenomena is of interest to paleoclimatology, stratigraphy, and archaeology. 1 Soils The mechanical and chemical rock degradation leads under assistance of organisms to soil formation.

Ceramics dating was attempted by means of alpha recoil tracks in muscovite inclusions (Sect. 2). Commonly, ceramic clays are fired at 7oo-8oo°C, and during cooling below the Curie temperature the prevailing magnetic field is thermoremanently frozen in. Archaeomagnetic dating (Chap.
