Refined radio-isotopic dating techniques have been applied to Orgnac 3, a Late Acheulean and Early Middle Palaeolithic site in France. Evidence of Levallois core technology appeared in level 4b in the middle of the sequence, became predominant in the upper horizons, and was best represented in uppermost level 1, making the site one of the

Radiometric dating has now been used for almost 50 years to establish “beyond doubt” the earth's multi-billion year geological column. Although this column and its “age” was firmly settled well before the advent of radiometric dating, the latter has been successfully used to help quantify the “ages” of the strata and the fossils in

Techniques directly dating fault slip are few, limiting the ability to interpret the rock record of seismicity. Hematite is commonly found in fault zones, amenable to (U-Th)/He dating, and slip surface hematite may be reset by shear heating events and/or recrystallization.
