Other types with dark bands or mottling in gray green or yellow are also known. Two subsequent refinements of obsidian hydration dating (OHD)-empirical rate dating and The principle is to measure the concentration of H. Obsidian : Obsidian is an aluminosilicate, or rhyolitic, glass, formed by rapid cooling of volcanic magma under the proper geologic conditions.
This overview was written to help absolute beginners get started. The water diffusion mechanism in obsidian has been revisited with the advent of a new dating approach employing secondary ion mass. The full text of this article hosted at iucr.
Obsidian outcrops all over the world, and was preferentially used by stone tool makers because it is very easy to work with, it is very sharp when broken, and it comes in a variety of vivid colors, black, orange, red, green and clear.

Obsidian hydration dating OHD is a geochemical method of determining age in either absolute or relative terms of an artifact made of obsidian. They introduced the obsidian hydration dating method to the archaeological community in It may be used in two ways: as a relative dating method to. Obsidian, or volcanic glass, is formed by the rapid cooling of silica-rich lava.
Absolute chronology including radiocarbon dating typically focused on the beginning of obsidian-hydration dating in archaeology. Obsidian hydration dating (or OHD) is a scientific dating technique, which uses the understanding of the geochemical nature of the volcanic.
The principle behind obsidian hydration dating is simple–the longer the artifact surface has been exposed, the thicker the hydration band will.
