How do archaeologists choose where to excavate?

How do archaeologists choose where to excavate?

To determine where a site might be, archaeologists conduct a survey, which can include walking through a site and digging holes of similar depths at an equal distance apart from each other, known as shovel test pits, as well as GPS, resistivity meters, and ground penetrating radars.

How might you choose an excavation site?

By studying the complexities of the existing land, archaeologists can often extrapolate what the area would have looked like hundreds or thousands of years ago, and thus determine (or guess) what a likely place for a settlement would be.

How do archaeologists excavate?

Excavating a Unit Archaeologists use a statistical sampling method to select which squares or units they will excavate. To begin, they will collect surface artifacts, then remove any ground vegetation. Archaeologists screen all soil removed from a unit to recover small artifacts and ecofacts.

What techniques do archaeologists use?

Of the many geophysical techniques that exist, archaeologists generally make use of four: magnetic gradiometry, earth resistance, ground penetrating radar (GPR) and magnetic susceptibility. Each technique measures some aspect of the ground below the surface.

What factors will determine the depth of excavation and the ground support methods adopted?

depth of the excavation. soil properties, including variable soil types, stability, shear strength, cohesion, presence of ground water, effect of exposure to the elements.

What is the process involved in excavation?

Excavation is the process of moving earth, rock or other materials with tools, equipment or explosives. It includes earthwork, trenching, wall shafts, tunneling and underground. Some of the different processes used in excavation include trenching, digging, dredging and site development.

What do archaeologists use to dig?

Generally during an excavation, an archaeologist’s tool box consists of some basic tools regardless of the type of excavation. Shovels, trowels, spades, brushes, sieves, and buckets are some of the more obvious or common tools that an archaeologist may carry with them to most digs.

What are the factors that affect the excavation?

The factors to consider include:

• Soil type.
• Depth of cut.
• Water content of soil.
• Changes due to weather or climate.
• Surcharge loads (e.g., spoil, other materials to be used in the trench) and.
• Other operations in the area.

How does the excavation of bones help archaeologists?

As discussed in Week 1, the skeletal elements may be positioned slightly differently in a skeleton buried in a void (i.e. coffin) compared to one in just an earth grave. Careful excavation can, therefore, reveal lots of ‘invisible’ information about the burials.

How do archaeologists prepare for excavations?

This preliminary work includes everything from consulting aerial photographs, old maps and physical references in literature, or even using high-tech methods like geophysical prospecting, a technique that measures electrical conductivity in soil. This type of meticulous fieldwork prepares archaeologists for planned excavations.

What do archaeologists do the least?

Today, excavation is probably what archaeologists do the least. That is not to say that the criticality of excavation has diminished within Archaeology.

Why is vertical excavation inappropriate for archaeological sites?

This method destroys removed layers, thus it is inappropriate for archaeological sites comprised of one or several successive occupations or settlements10. Vertical Excavation Vertical excavation is a significant method that archaeologists use to clarify chronology.

What are the alternatives to excavation in archeology?

Furthermore, there are now many alternatives to excavation for studying an archeological site, including surface archeology in which surface-exposed artifacts are detected and recorded; remote sensing; and the examination of soil and plant distributions. These techniques are nondestructive, and permit the archeologist to easily examine large areas.
