To generate a Harris Matrix from the provided section drawing of an archaeological feature, I will identify the stratigraphic layers and their relationships as depicted. This process involves interpreting the drawing to understand the sequence of events that each layer represents.
From the image, we can see several distinct layers, each with unique characteristics. Here's a description of the layers and their immediate stratigraphic relationships as they appear:
- The light gray gravel and sand at the topmost layer.
- Dark gray w/silt underneath the light gray gravel and sand.
- Lighter gray ash beneath the dark gray w/silt.
- Gray-black charcoal layer is directly below the lighter gray ash.
- Gray-black mottled w/ orange sand underneath the charcoal layer.
- Orange sand mixed w/ gray is found below the gray-black mottled w/ orange sand.
- Gray ash in shell layer sits beneath the orange sand mixed w/ gray.
Given these observations, I'll now outline the stratigraphic sequence, which reads from the oldest at the bottom to the newest at the top:
- The gray ash in the shell layer (oldest).
- Orange sand mixed w/ gray.
- Gray-black mottled w/ orange sand.
- Gray-black charcoal.
- Lighter gray ash.
- Dark gray w/silt.
- Light gray gravel and sand (newest).
With this sequence in mind, the Harris Matrix can be depicted using mermaid diagram syntax as follows:
%%{ init: { 'flowchart': { 'curve': 'linear' } } }%%
graph TD
L7("Gray Ash in Shell Layer")
L6("Orange Sand Mixed w/ Gray") --> L7
L5("Gray-Black Mottled w/ Orange Sand") --> L6
L4("Gray-Black Charcoal") --> L5
L3("Lighter Gray Ash") --> L4
L2("Dark Gray w/Silt") --> L3
L1("Light Gray Gravel and Sand") --> L2
This mermaid diagram script, when rendered, will produce a visual representation of the Harris Matrix for the section drawing, showing the chronological sequence of deposits.
