Radiocarbon Dating of Canvas Paintings: Two Case Studies
The application of radiocarbon dating to groundwater analysis can offer a technique to predict the over-pumping of the aquifer before it becomes contaminated or overexploited. In this study, the presence of car-. However, when considering the data measured on pig-.
Hand stencils, made by placing a hand on the wall and blowing pigment at it probably through a pipe of some kind , form a characteristic image of a roughly round area of solid pigment with the uncoloured shape of the hand in the centre, which may then be decorated with lines or dashes. Authentication by thermoluminescence," World of Tribal Arts , 1 4: More broadly, the success of radiocarbon dating stimulated interest in analytical and statistical approaches to archaeological data.

Its best known archaeological site is Pedra Furada. It has an area of The area has the largest concentration of prehistoric small farms on the American continents. Scientific studies confirm that the Capivara mountain range was densely populated in prehistoric periods.
Moreno National Park , which includes many sites of archaeological and paleontological importance. The hand images are often negative stencilled. Besides these there are also depictions of human beings, guanacos , rheas , felines and other animals, as well as geometric shapes, zigzag patterns, representations of the sun, and hunting scenes.
Similar paintings, though in smaller numbers, can be found in nearby caves. There are also red dots on the ceilings, probably made by submerging their hunting bolas in ink, and then throwing them up. The colours of the paintings vary from red made from hematite to white, black or yellow. The negative hand impressions date to around BCE, the positive impressions from BCE, while the hunting drawings are calculated to more than 10, years old.
There are rock paintings in caves in Thailand, Malaysia, Indonesia, and Burma. The anthropologist Ivor Hugh Norman Evans visited Malaysia in the early s and found that some of the tribes especially Negritos were still producing cave paintings and had added depictions of modern objects including what are believed to be cars.
In Indonesia the caves at Maros in Sulawesi are famous for their hand prints. About negative handprints have also been found in 30 painted caves in the Sangkulirang area of Kalimantan; preliminary dating analysis puts their age in the range of 10, years old. Dr Maxime Aubert, of Griffith University in Queensland , Australia, said that the minimum age for the outline of a hand was 39, years old, which made it "the oldest hand stencil in the world" and added, "Next to it is a pig that has a minimum age of 35, years old, and this is one of the oldest figurative depictions in the world, if not the oldest one.
The Padah-Lin Caves of Burma contain 11,year-old paintings and many rock tools. In the Philippines at Tabon Caves the oldest artwork may be a relief of a shark above the cave entrance. It was partially disfigured by a later jar burial scene.
Originating in the Paleolithic period, the rock art found in Khoit Tsenkher Cave , Mongolia, includes symbols and animal forms painted from the walls up to the ceiling.
The paintings appear brown or red in color, and are stylistically similar to other Paleolithic rock art from around the world but are unlike any other examples in Mongolia.

Because of the half-lives of U, nd, and 40K are very long, their concentrations in the object, and hence the radiation dose they provide per year, have remained fairly constant. The most suitable type of sample for thermoluminescence dating is pottery, though the date gotten will be for the last time the object was fired.
Application of this method of age determination is limited to those periods of pottery and fired clay availability from about BC to the present. University Branch S.
