Obsidian Hydration Dating

Obsidian Hydration Dating

Chronometric Dating in Archaeology pp Cite as. A freshly-made surface of obsidian volcanic glass of rhyolitic composition will absorb water which slowly penetrates by diffusion into the body of the artifact. Although the depth of penetration can be measured by various methods, it is generally determined by microscopic examination on thin sections of the artifact cut normal to the surface. The rate of penetration of water is dependent upon several factors, primarily the chemical composition of the glass and the temperature at which the hydration occurred. Discussions are given of techniques for measuring the hydration thickness, measurement or estimates of ambient hydration temperature, chemical composition of the obsidian, and the conversion of hydration thickness to dating the time of manufacture of the artifact. Comparisons are made between the results of obsidian hydration and other dating methods. Skip to main content Skip to sections.

It’s not that I don’t think Google Glass is stranger than walking up to a stranger and putting your finger in his or her ear.

It’s precisely because of Google Glass’s sheer strangeness that I want to know whether it would alter my approach to love. Would I think — or even feel — something different? Would I have to dip my head to an unforeseen angle in order to avoid being poked? Most importantly, would I care whether the camera is on or off? Sadly, some who bowed, scraped, and applied to own one of the these gadgets have already begun to experiment with seeing how Google Glass might alter their love lives.

Date: Archaeometry, Available online 29 June Abstract: The first deliberate manufacture of glass occurs in the sixteenth century BC, although the origin of the material is still a focus of debate; Egypt or Mesopotamia being the most likely innovator. The conventional approach is that glass technology first developed in Mesopotamia Barag, , p; Moorey, , p; Shortland et al.

Although there is textual and iconographic evidence for the production, supply and transport of glass between Egypt, its vassal Levantine states and Mesopotamia, it is very rare to find Egyptian glass in Mesopotamia or vice versa Walton et al. The exceptions to date are two green glass rods found in Amarna, Egypt, which have trace element compositions consistent with Mesopotamian glass, and a collection of blue glass beads and a scarab recovered from a tomb in Gurob, Egypt, which also showed compositional consistency with glasses of known Mesopotamian origin Varberg et al.

Fission track dating is a radiometric dating technique based on analyses of the damage trails, or tracks, left by fission fragments in certain uranium -bearing minerals and glasses. The method involves using the number of fission events produced from the spontaneous decay of uranium in common accessory minerals to date the time of rock cooling below closure temperature. Fission tracks are sensitive to heat, and therefore the technique is useful at unraveling the thermal evolution of rocks and minerals.

Most current research using fission tracks is aimed at: a understanding the evolution of mountain belts; b determining the source or provenance of sediments; c studying the thermal evolution of basins ; d determining the age of poorly dated strata ; and e dating and provenance determination of archeological artifacts. Unlike other isotopic dating methods, the ” daughter ” in fission track dating is an effect in the crystal rather than a daughter isotope. Uranium undergoes spontaneous fission decay at a known rate, and it is the only isotope with a decay rate that is relevant to the significant production of natural fission tracks; other isotopes have fission decay rates too slow to be of consequence.

No back seat smooches for you. They’ve tried and failed at contacts- They gave them a go, but after all the fuss of infections and the amount of stuff needed to wear them- they gave up and went back their tried and trusted spectacles. And you’re a little bit thankful- the green goo in their eyes of a morning was not the most attractive of looks. If it’s hot out- And they get a little face sweat- they go from sexy secretary to clammy co-worker in a matter of minutes.

Kissing can be interesting – The glasses often poke you in the eye mid-snog thus ruining the moment for you both.
