The use of percussion drilling to obtain core samples from rock-shelter deposits

How many excavators of deep palaeolithic sites, especially in caves or rock-shelters, dig with any clear knowledge of how deep the deposits they are working in actually are, or of the ages of the lower portions? Here an alternative is offered to the traditional approach by a ‘deep sounding’ of conventional excavation. A crucial element to the strategy at Klithi is the possibility of carbon-dating, by accelerator, samples of the small size commonly obtained from a drilled core.
