Buried History: Do you know how archaeologists uncover the mysteries of layers?
Archaeology is a mysterious subject, and one of its core concepts is stratigraphy. This technique is not only the cornerstone of archaeological excavations, but also helps archaeologists deeply analyze and understand the history of a site and the culture it represents. The concept of stratigraphy originates from geology and emphasizes the accumulation of sediments in layers according to the principle of equilibrium. Therefore, archaeologists need to clearly identify the network context of each discovery in order to unravel the mysteries of the buried objects.
During archaeological excavations, it is important to ensure that the context of each layer is preserved so that ancient behaviors and environments can be better interpreted.
In archeology, the concept of strata is not static, but is formed through the dynamic superposition of "contexts." Each context is an independent event or act and leaves identifiable traces in the archaeological sequence. These contexts can be sediments, structures, or even sections. The task of archaeologists is to unearth and understand how these contexts were created. For example, a ditch might represent an act of "cutting," allowing archaeologists to better understand the impact of that activity on the area.
Basic principles of stratigraphy
In the practice of stratigraphy, archaeologists follow some generally recognized principles. These principles are not only derived from geological theory, but also incorporate the unique needs of archaeology. Among them, E.C. Harris identified several basic principles.
"In a series of levels and interface features, the upper-level unit created by originality must be younger, while the lower-level unit must be older."
For example, the uppermost layer must be the youngest, meaning that all layers below it must have been formed earlier. This principle helps to infer the chronological representation of archaeological strata.
Contextual combination and explanation
Understanding an archaeological site requires bringing together the various contexts. Archaeologists group these into larger groups based on their contextual relationships. For example, a burial archeology might include three contexts: the burial incision, the remains, and the backfill above them. These groups can be further combined into larger concepts of "stages," which may paint a more historical picture of what was observed at a certain point in time.
Stratigraphic dating
Sometimes, archaeologists wish to date activities rather than simply the age of artifacts. By analyzing the context revealed, archaeologists are able to date these specific events with relative accuracy. If a context is enclosed by two determinable levels, then the date of formation of the context must be between these two levels. This reasoning can provide a clear perspective on the time frame in which the event occurred.
"In archaeology, understanding the location of context is not only a matter of time sequence, but also the key to understanding cultural behavior."
Residual and invasive findings
However, a challenge in inferring the age of artifacts is that artifacts in one context are not necessarily representative of the age of that context. Sometimes these artifacts may have been transported from other, earlier layers, obscuring the information available to archaeologists. These artifacts are called "residual finds," and according to new archaeological steps, there may be later artifacts in higher contexts, which may contaminate the interpretation of earlier contexts.
Archiving issues of digital data
In the digital age, although archaeological data archiving is necessary, it inevitably faces some challenges. Much data exists only on paper or in scanned images, making reuse difficult. In response to this phenomenon, the archaeological community has also proposed some solutions, hoping to improve the current data management methods.
Both archaeologists and researchers conducting excavations must have a good understanding of the importance of stratigraphy. This concept is not only a cornerstone of archeology but also the story of our past. Therefore, we cannot help but ask: Can archaeological discoveries reveal the wisdom of ancient civilizations and trigger our reflection and enlightenment on modern society?
