Ban Chiang
Ban Chiang (, ; , ) is an archaeological site in Nong Han district, Udon Thani province, Thailand. It has been a UNESCO World Heritage Site since 1992. Discovered in 1966, the site first attracted interest due to its ancient red-painted pottery. More recently, it gained international attention in 2008 when the United States Department of Justice, following an undercover investigation begun in 2003, raided several museums for their role in trafficking in Ban Chiang antiquities. Discovery Villagers had uncovered some of the pottery in prior years without insight into their age or historical importance. In August 1966, Steve Young, a political science student at Harvard College, was living in the village conducting interviews for his senior honors thesis. Young, a speaker of Thai, was familiar with the work of Wilhelm Solheim and his theory of the possible ancient origins of civilization in Southeast Asia. One day while walking down a path in Ban Chiang with his assistant, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phytolith
Phytoliths (from Greek language, Greek, "plant stone") are rigid, microscopic mineral deposits found in some plant tissues, often persisting after the decay of the plant. Although some use "phytolith" to refer to all mineral secretions by plants, it more commonly refers to Silicon dioxide, siliceous plant remains. Phytoliths come in varying shapes and sizes. The plants which exhibit them take up dissolved silica from the groundwater, whereupon it is deposited within different intracellular and extracellular structures of the plant.Piperno, Dolores R. (2006). Phytoliths: A Comprehensive Guide for Archaeologists and Paleoecologists. AltaMira Press . The silica is absorbed in the form of orthosilicic acid, monosilicic acid (Si(OH)4), and is carried by the plant's Circulatory system, vascular system to the cell walls, cell lumen, and intercellular spaces. Depending on the plant Taxon, taxa and soil condition, absorbed silica can range from 0.1% to 10% of the plant's total dry weight ...

Radiocarbon Dating
Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for Chronological dating, determining the age of an object containing organic material by using the properties of carbon-14, radiocarbon, a radioactive Isotopes of carbon, isotope of carbon. The method was developed in the late 1940s at the University of Chicago by Willard Libby. It is based on the fact that radiocarbon () is constantly being created in the Atmosphere of Earth, Earth's atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting combines with atmospheric oxygen to form radioactive carbon dioxide, which is incorporated into plants by photosynthesis; animals then acquire by eating the plants. When the animal or plant dies, it stops exchanging carbon with its environment, and thereafter the amount of it contains begins to decrease as the undergoes radioactive decay. Measuring the amount of in a sample from a dead plant or animal, such as a piece of w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermoluminescence Dating
Thermoluminescence dating (TL) is the determination, by means of measuring the accumulated radiation dose, of the time elapsed since material containing crystalline minerals was either heated (lava, ceramics) or exposed to sunlight (sediments). As a crystalline material is heated during measurements, the process of thermoluminescence starts. Thermoluminescence emits a weak light signal that is proportional to the radiation dose absorbed by the material. It is a type of luminescence dating. The technique has wide application, and is relatively cheap at some US$300–700 per object; ideally a number of samples are tested. Sediments are more expensive to date. , University of Wollongong, Australia [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ban Non Wat
Ban Non Wat is a village in Thailand, in the Non Sung district, Nakhon Ratchasima Province, located near the small city of Phimai. It has been the subject of excavation since 2002. The cultural sequence encompasses 11 prehistoric phases, which include 640 burials.Higham, C. F. W. (2011). The Bronze Age of Southeast Asia: New insight on social change from Ban Non Wat. Cambridge Archaeological Journal, 21(3), 365-389. The site is associated with consistent occupation, and in modern-day Ban Non Wat the occupied village is located closer to the Mun River. Excavations show that people were occupying the region during the Neolithic, Bronze, and Iron Ages. This unique sequence has been proven by 76 radiocarbon determinations treated with Bayesian analyses. Bayesian analysis is the use of Bayesian statistics to calibrate radiocarbon dates to receive a more accurate date. Soil in the Ban Non Wat area may displace the Bayesian analysis. These reveal that the initial Neolithic settlement ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crucible
A crucible is a container in which metals or other substances may be melted or subjected to very high temperatures. Although crucibles have historically tended to be made out of clay, they can be made from any material that withstands temperatures high enough to melt or otherwise alter its contents. History Typology and chronology The form of the crucible has varied through time, with designs reflecting the process for which they are used, as well as regional variation. The earliest crucible forms derive from the sixth/fifth millennium B.C. in Eastern Europe and Iran. Chalcolithic Crucibles used for copper smelting were generally wide shallow vessels made from clay that lacks refractory properties which is similar to the types of clay used in other ceramics of the time. During the Chalcolithic period, crucibles were heated from the top by using blowpipes.Hauptmann A., 2003, ''Developments in copper Metallurgy During the Fourth and Third Millennia B.C. at Feinan'', Jordan, P ...

Chester Gorman
Chester F. Gorman (March 11, 1938 – June 7, 1981) was an American anthropologist and archaeologist. Born in Oakland, California, he grew up on his parents' dairy farm in Elk Grove. He studied at the Sacramento State University and the University of Hawaiʻi, where he also got his MA and his PhD. Chester Gorman worked mostly in Southeast Asia. Among the most significant sites he worked are Ban Chiang in northeast Thailand and Spirit Cave in northwest Thailand, one of the major Hoabinhian sites. While surveying for sites in northeast Thailand with Wilhelm Solheim between 1963-1964, Gorman also discovered the site of Non Nok Tha. Gorman excavated Spirit Cave (Tham Phii Man) once in 1966 for his dissertation research, and again in 1971. He also excavated Banyan Valley Cave (Tham Sai) in 1972 and Steep Cliff Cave (Tham Phaa Can) in 1973. He died of cancer at age 43 in Sacramento Sacramento ( or ; ; ) is the capital city of the U.S. state of California and the seat of S ...

University Of Pennsylvania Museum
A university () is an institution of tertiary education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase , which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law and notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hilde''A History of the University in Europe: Volume 1, Universities in the ...

Iron Age
The Iron Age () is the final epoch of the three historical Metal Ages, after the Chalcolithic and Bronze Age. It has also been considered as the final age of the three-age division starting with prehistory (before recorded history) and progressing to protohistory (before written history). In this usage, it is preceded by the Stone Age (subdivided into the Paleolithic, Mesolithic and Neolithic) and Bronze Age. These concepts originated for describing Iron Age Europe and the ancient Near East. In the archaeology of the Americas, a five-period system is conventionally used instead; indigenous cultures there did not develop an iron economy in the pre-Columbian era, though some did work copper and bronze. Indigenous metalworking arrived in Australia with European contact. Although meteoric iron has been used for millennia in many regions, the beginning of the Iron Age is defined locally around the world by archaeological convention when the production of Smelting, smelted iron (espe ...

Neolithic
The Neolithic or New Stone Age (from Ancient Greek, Greek 'new' and 'stone') is an archaeological period, the final division of the Stone Age in Mesopotamia, Asia, Europe and Africa (c. 10,000 BCE to c. 2,000 BCE). It saw the Neolithic Revolution, a wide-ranging set of developments that appear to have arisen independently in several parts of the world. This "Neolithic package" included the History of agriculture, introduction of farming, domestication of animals, and change from a hunter-gatherer lifestyle to one of sedentism, settlement. The term 'Neolithic' was coined by John Lubbock, 1st Baron Avebury, Sir John Lubbock in 1865 as a refinement of the three-age system. The Neolithic began about 12,000 years ago, when farming appeared in the Epipalaeolithic Near East and Mesopotamia, and later in other parts of the world. It lasted in the Near East until the transitional period of the Chalcolithic (Copper Age) from about 6,500 years ago (4500 BCE), marked by the development ...

Bronze Age
The Bronze Age () was a historical period characterised principally by the use of bronze tools and the development of complex urban societies, as well as the adoption of writing in some areas. The Bronze Age is the middle principal period of the three-age system, following the Stone Age and preceding the Iron Age. Conceived as a global era, the Bronze Age follows the Neolithic, with a transition period between the two known as the Chalcolithic. The final decades of the Bronze Age in the Mediterranean basin are often characterised as a period of widespread societal collapse known as the Late Bronze Age collapse (), although its severity and scope are debated among scholars. An ancient civilisation is deemed to be part of the Bronze Age if it either produced bronze by smelting its own copper and alloying it with tin, arsenic, or other metals, or traded other items for bronze from producing areas elsewhere. Bronze Age cultures were the first to History of writing, develop writin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
