The initial chronological hypotheses Henri Breuil and Denis Peyrony established an association with the Gravettian. For Breuil, the chronology of Palaeolithic parietal art depended on the existence of two cycles: one Aurignacian-Perigordian, and the other Solutrean-Magdalenian. He drew parallels between Lascaux and the painted figures found in stratigraphy — and thus reliably dated — at the Labattut Perigordian and Blanchard Aurignacian shelters. A more nuanced evaluation was advanced by Annette Laming, who pointed out that this iconography displayed characteristics that could be attributed to either of the two major cycles. Initial radiocarbon dating tests In , fragments of charcoal from the excavations in the Shaft were analysed in the Chicago laboratory of Willard Libby, who had pioneered the method. The results, a date of 15, years BP, placed Lascaux in the Magdalenian culture. He concluded that Lascaux was Solutrean. These successive adjustments show the difficulties in establishing a precise, well-argued chronological scheme. A formal analysis of the figures at Lascaux leads one to think that the art belongs to a Solutrean tradition. Clearly, they are more reminiscent of the works at the well-dated sites of Fourneau-du-Diable or Roc-de-Sers, than of any Magdalenian example.

M oira Weigel , the author of Labor of Love: The Invention of Dating , argues that dating as we know it—single people going out together to restaurants, bars, movies, and other commercial or semicommercial spaces—came about in the late 19th century. What dating does is it takes that process out of the home, out of supervised and mostly noncommercial spaces, to movie theaters and dance halls. The application of the supply-and-demand concept, Weigel said, may have come into the picture in the late 19th century, when American cities were exploding in population.

Dendrochronology or tree-ring dating is the scientific method of dating tree rings also called growth rings to the exact year they were formed. As well as dating them this can give data for dendroclimatology , the study of climate and atmospheric conditions during different periods in history from wood. Dendrochronology is useful for determining the precise age of samples, especially those that are too recent for radiocarbon dating , which always produces a range rather than an exact date.

However, for a precise date of the death of the tree a full sample to the edge is needed, which most trimmed timber will not provide.

Sobre a ADIT Brasil

Optically-Stimulated Luminescence is a late Quaternary dating technique used to date the last time quartz sediment was exposed to light. As sediment is transported by wind, water, or ice, it is exposed to sunlight and zeroed of any previous luminescence signal. Once this sediment is deposited and subsequently buried, it is removed from light and is exposed to low levels of natural radiation in the surrounding sediment.

Through geologic time, quartz minerals accumulate a luminescence signal as ionizing radiation excites electrons within parent nuclei in the crystal lattice. A certain percent of the freed electrons become trapped in defects or holes in the crystal lattice of the quartz sand grain referred to as luminescent centers and accumulate over time Aitken,

For singles looking to meet a special person without the help of social media, speed dating events could hold the answer. Attendees embark on a number of quick-fire encounters and a bell or buzzer rings when each timed date has come to an end. Participants progress from one table to the next, until everyone has had a chance to meet each other. To get a sense of the kinds of speed dating events there are , you can search the Eventbrite platform. Speed dating event organisers should always be clear about who their event is for by giving a suggested age range and sexual orientation — for example, is the event for men to meet women, for men to meet men, and so on.

First of all, think about how long you want to give participants to get to know each other — the length of each speed date will vary depending on the organiser, although the norm is usually between three and eight minutes.

Multiply the number of minutes by the number of dates that will take place and add on time at the start for everyone to arrive and take their places and time at the end for people to think about who they might like to see again. First stop: secure a venue. Restaurants and bars tend to work really well as do other sociable spaces, such as coffee shops, student unions and co-working hubs.
