Here, in the Serrezuela mountain range, members of the Fundación Instituto de Investigación y Evolución Humana (FIPEH) have identified archaeological sites that point to human presence dating from 100,000 to 4,000 Before Present (BP).
In 2017, a cave called Cueva del Rio Cuadros, was identified and found to extend over 400 meters.
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.
By making multiple measurements (you need at least two for a date estimate) we can find out how much radiation the item was exposed to over the years and can get dating estimates related to when the item was last heated.
This method has the following restrictions: a) It cannot be used to date items many thousands of years old; b) it can only be used in non-organic materials; and c) the materials to be dated must have been heated to more than 350 degrees Celsius. All of the current dating methods are going through refinement.
This process frees energy in the form of light, which can be measured.Room and Board Arrangements: Accommodations are in shared rooms (4-6 beds) located in Municipal Dormitory (Residencia Municipal) in the town of Bedmar. The common areas are cleaned once a week by professional cleaners.Breakfast, lunch and dinner will be provided 7 days a week at the residence. There will be special recipes for those who have dietary restrictions such as diabetes, allergies or gluten intolerance and vegetarians.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.
Archaeologists are seeking an accurate dating technique, but this method is yet to be found.
