Site Formation in Archaeology Teacher Directions There are generally four ways archaeological sites are formed. These include: • construction on site • abandonment of the site • site use • decay or destruction of the site Any or all of these processes could be identified for any one site. This is one reason why

Unit Excavations. Initial testing of a site might include excavation of a 2 x 2 meter unit, dug in 5 or 10 cm levels, with all soil screened. Units are useful for examining the different layers or strata in the site because the units can examine many levels of the site fairly quickly.

In the past 10 years, flotation techniques have been introduced and implemented in Chinese archaeology. As a result, a tremendous quantity of plant remains have been recovered from archaeological sites located all over China. These plant remains include crops that might have been domesticated in China—such as rice, foxtail millet, …

5 A method Flotation and wet-sieving are usually run as a single, three-step process, which has a sample of archaeological soil at the start and a series of bags of dried archaeological material at the end [Figure 1]. The flotation and wet-sieving are best run as a continuous process in one area, with the sorting done under cover at the dig ...

It is argued that, without use of such a flotation procedure, inferences about prehistoric subsistence patterns from faunal and floral remains are sharply biased in favor of larger animals and in favor of hunting, over natural plant food collecting, since conventional screens are not adequate for recovery of most plant remains or small animal ...

Flotation (also called "water separation") is a method of recovering minute archaeological materials from soil—especially carbonized plant remains—that would otherwise escape an archaeologist's eye. The evidence obtained through this inexpensive technique can provide precious data about the ancient economy, rituals, diet, and natural environment. Here's …

The Ethnobotany Laboratory processes soil samples from all OAS excavations, as well as contracting with other agencies and individuals. The soil samples are poured into a bucket of water and agitated that causes the lighter botanical materials (called the light fraction) to float. These materials are decanted on to a piece of fine mesh material.
