This involves the removal of fine materials, such as sand, from an area. In such cases, excavation will consist of clearing away wide, shallow swaths of material. Several methods are available to achieve excavation. During excavation, archaeologists often use stratigraphic excavation to remove phases of the site one layer at a time. But rectangular plots are more useful. Our excavation and sampling programmes are tailored to meet our project objectives, through targeted excavation and analyses of material culture, technology and plant and animal remains. Tweet Pin It. Any open excavation that is deeper than 1.5 meter needs side stability by sloping, benching or shoring. The results obtained from this experimental study show that the Quadrant Excavation method and Standard Context Recording system was the most consistent, efficient, and reliable archaeological approach to use to excavate and record clandestine burials and to formulate interpretation-based narratives of a grave’s formation sequence. If this approach is unable to be utilised the Demirant Excavation method or the Stratigraphic Excavation method should be used.
