Heart of Gold Lesson Plan Year 7

Depending on where the gold is found, this may be done by panning or through dry blowing. Each of these methods relies on the property of density. As gold has a very high density compared to the rock, soil and sediments it is contained in, it can be separated out by exploiting this property as it will fall to the bottom of mixtures that are allowed to settle out. The process of panning is used when small pieces of gold are found in creeks and rivers. It involves using a large shallow dish (pan) to scoop out some of the sediments in the riverbed and a small amount of water. You use a swirling motion with the pan tipped away from you and allow small amounts of the sediments and water to spill over the edge of the pan. When you have only a small amount of the sediments remaining in the pan, you will be able to see any gold particles that remain at the bottom of the pan. During the West Australian gold rush, most of the gold was being found in dry areas and water was a scarce commodity. -

Gravity Separation: Gold Panning Gold concentrated by washing lighter river sands with water Leaves dense gold particles Alternative- wash gold-bearing sand and gravel over a woollen fleece Traps heavier gold dust that would sink into the wool fibres. Advantages • Simplicity Disadvantages • Labour intensive Gravity Separation: Sluicing • Water is channelled to flow through a sluice-box. • Sluice-box is essentially a man-made channel with riffles (barriers) at the bottom. • Riffles create dead-zones in the water current which allows gold to drop out of suspension. Sluicing and panning results in the direct recovery of small gold nuggets and flakes. Gold Parting: Salt Cementation Process • Invented to remove Ag from Au-Ag mixtures around 6th century BC. Mix: argentiferous gold foil, common salt, brick dust or burnt clay and urine in a sealed container. -

Perspectives from Cranial and Dental Affinity of the Human Remains from Iron Age Phum Snay, Cambodia Hirofumi MATSUMURA1*, Kate M

The purpose of the research is to address the origin of these pre-Angkorian people. Multivariate comparisons using cranial and dental metrics, as well as dental nonmetric traits, demonstrate that the characteristic affinities intermediate between the early Holocene Hoabinhian groups akin to Australo-Melanesians and the present-day people in the mainland Southeast Asia. This finding suggests that the ancient people of Phum Snay preserved genetic traits of early in- digenous populations, whereas modern mainland Southeast Asians, including Cambodians, were more affected by gene flow from later migrants from East Asia into this region.

Southeast Asia Bioarchaeology Newsletter
Southeast Asia Bioarchaeology Newsletter Issue No 3 April 2006 Edited by Kate Domett [email protected] Welcome to the third annual newsletter designed to update you on the latest news in the field of bioarchaeology in Southeast Asia. News From: Michael Pietrusewsky University of Hawaii, Honolulu Email: [email protected] NEWS FROM THE UNIVERSITY OF HAWAII, HONOLULU Michael Pietrusewsky, Rona Ikehara, and Michele Toomay Douglas presented a paper at the 18th Congress of the Indo- Pacific Prehistory Association (IPPA) Congress in Manila, Philippines, March 20-26, 2006, entitled “The Bioarchaeology of the Vat Komnou Cemetery, Angkor Borei, Cambodia”. Approximately 60 inhumation burials, of varying states of completeness and preservation, dated between 200 B.C. and A.D. 400 (or the early historic period in the Mekong delta) were excavated at the Vat Komnou cemetery Angkor Borei, Cambodia, by the University of Hawaii and the Royal University of Fine Arts in 1999 and 2000. The cemetery contained the remains of all age groups from infants to old adults. Over 40% of the burials are subadults. Adult males outnumber females 2 to 1 and most of the adults died as young adults. Osteological analyses are beginning to provide us with our first glimpses of these protohistoric people, associated with early Khmer culture, including evidence of health, disease, physiological stress, injury, physical activity, subsistence, length of life, and cultural modification of bone and teeth. Among the findings are tooth caries, moderate to extreme tooth attrition, and evidence of periodontal disease. Possible cultural modifications of the teeth include staining of the tooth enamel most likely due to chewing betel nut and tooth filing. -
Mid-Holocene Hunter-Gatherers ‘Gaomiao’ in Hunan, China: the First of the Two-Layer Model in the Population History of East/Southeast Asia
4 Mid-Holocene Hunter-Gatherers ‘Gaomiao’ in Hunan, China: The First of the Two-layer Model in the Population History of East/Southeast Asia Hirofumi Matsumura, Hsiao-chun Hung, Nguyen Lan Cuong, Ya-feng Zhao, Gang He and Zhang Chi Gaomiao, the eponymous archaeological site of the Gaomiao Culture (ca. 7500–5500 BP) has produced evidence of a unique hunter-gatherer society in Hunan Province, China, that produced fine decorated pottery. The human remains unearthed from this site provided an excellent opportunity to assess phenotypic and biological relationships between the Gaomiao and prehistoric and modern human populations that have inhabited East/Southeast Asia over the past ca. 10,000 years through cranial morphometrics. The assessment of morphometric affinity presented here addresses the peopling of East Asia, particularly in the context of the ‘two-layer’ hypothesis describing the population history of this region. The results suggest that the Gaomiao skeletons inherited genetic signatures from early colonising populations of Late Pleistocene southern Eurasian origin to a certain extent, and might share a common ancestry with present-day Australian Aboriginal and Melanesian people. Introduction The study of the population history of East Asia remains complex due to various migration processes and intermixing of populations throughout prehistory, poor archaeological sample sizes and limited radiometric dating. In general terms, East Asia is thought to have been originally inhabited by (to use the classic term) ‘Mongoloid’ peoples from the Late Pleistocene onwards. In the Late Pleistocene and early Holocene of Southeast Asia, several sets of human remains exhibit Australo-Melanesian characteristics, and it has been argued that an indigenous population possessing this morphological form occupied Southeast Asia.
