The first method was based on radioactive elements whose property of decay occurs at a constant rate, known as the half-life of the isotope.

Today, many different radioactive elements have been used, but the most famous absolute dating method is radiocarbon dating, which uses the isotope C.

Relative techniques can determine the sequence of events but not the precise date of an event, making these methods unreliable.

b) Absolute These methods are based on calculating the date of artefacts in a more precise way using different attributes of materials.

Thus, I think my question is more about Chemistry rather than Physics /maybe I'm wrong, of course : P/I'm interested in narrower time-frames, e.g. For example, how can we determine whether a statue is from Antiquity or from the Renaissance (assuming there are no erosion and other visual marks on it)? Or are you asking about the age of a statue since it was made from that rock?"Our finding disproves the long-standing assumption that Homo habilis was the first tool maker." The discovery was announced in a paper, 3.3-million-year-old stone tools from Lomekwi 3, West Turkana, Kenya, published on May 21 in . Harmand, the lead author, says that the Lomekwi 3 artifacts show that at least one group of ancient hominin started intentionally "knapping" stones -- breaking off pieces with quick, hard strikes from another stone -- to make sharp tools long before previously thought.In the 1930s, paleoanthropologists Louis and Mary Leakey unearthed early stone artifacts at Olduvai Gorge in Tanzania and named them the Oldowan tool culture.Weathering of a surface can provide information, providing the object has been exposed to known atmospheric conditions; but a buried statue would erode differently from one on the surface.For stones, or better, for ceramics, that have been heated, thermoluminescence provides an accurate way to measure age (or at least time since last being heated).

This isotope, which can be found in organic materials and can be used only to date organic materials, has been incorrectly used by many to make dating assumptions for non-organic material such as stone buildings.
