Learn About Archaeological Methods

Archaeological methods are techniques and procedures used to uncover, investigate, and analyze material remains from past human societies. Each method provides unique insights into different aspects of ancient life and culture. Here's a list of key archaeological methods, their nature, and when to use them:

​

1. Survey Methods

a. Pedestrian Survey

Nature: Pedestrian survey, also known as walkover survey, involves systematically walking over a landscape and visually inspecting the ground surface for artifacts and features. Surveyors often map these findings to identify patterns and site boundaries.

When to Use:

• Site Identification: When looking to locate new archaeological sites or understand the extent of known sites, pedestrian surveys are ideal. This method provides an initial understanding of the area's archaeological potential without invasive techniques.

• Preliminary Assessments: Use this method to gather initial data before committing to more invasive methods like excavation.

b. Shovel Probe Tests

Nature: Shovel probe tests involve digging small holes, typically less than a meter deep, at regular intervals across a survey area. These probes are used to sample subsurface soils and identify buried artifacts or features.

When to Use:

• Subsurface Exploration: When it's necessary to investigate below the surface to detect buried artifacts or features that are not visible on the surface.

• Site Potential Evaluation: Use this method to assess the archaeological potential of a site before deciding on larger-scale excavation.

c. Test Pits

Nature: Test pits are small, systematically placed excavation units used to sample soil and artifacts. They help determine the presence, extent, and depth of archaeological deposits.

When to Use:

• Site Evaluation: When assessing the potential of a site before full-scale excavation, test pits provide crucial information on soil stratigraphy and artifact distribution.

• Sampling: Use test pits to gather preliminary data that informs decisions about further excavation efforts.

c. Conductivity Surveys

Nature: Conductivity surveys measure how easily electric currents pass through the soil, identifying variations caused by buried features.

When to Use:

• Subsurface Features: Use to detect variations in soil composition and locate buried features.

• Environmental Context: Suitable for identifying areas of different soil properties related to archaeological activity.

d. Metal detecting

Nature: Metal detectors use electromagnetic fields to detect metallic objects buried in the ground. They emit signals when they come into contact with metal.

When to Use:

• Artifact Recovery: Use metal detectors to locate and recover metal artifacts such as coins, tools, and weapons.

• Preliminary Surveys: Ideal for initial surveys to identify areas of interest with metal concentrations before more invasive methods are applied.

5. Artifact Analysis Methods

a. Typology

Nature: Typology involves classifying artifacts based on their physical characteristics, such as shape, material, and decoration.

When to Use:

• Post-Excavation: Use to classify and compare artifacts after excavation.

• Cultural Interpretation: Ideal for understanding cultural variations and chronological changes.

b. Microscopic Analysis

Nature: This method uses microscopes to examine the fine details of artifacts, such as tool marks, wear patterns, and residue.

When to Use:

• Tool Use and Manufacture: Perfect for studying how artifacts were made and used.

• Residue Analysis: Use to detect traces of materials or substances on artifacts.

c. Chemical Composition Studies

Nature: Chemical analysis determines the elemental or molecular composition of artifacts, helping to identify their source and manufacturing techniques.

When to Use:

• Provenance Studies: Use to trace the origins of raw materials.
