Shale, Mudstone & Clay

Fine-grained sedimentary rocks in archaeology: firing behavior, breakage patterns, and common misidentifications.

Stratigraphy Basics

Reading layers: superposition, contacts, and why context matters as much as the stone itself.

Fossils & Microfossils

When fossils help with identification—and when they can mislead without proper sampling.

Cement & Porosity

Calcite vs silica cement, pore spaces, and how they affect weathering, staining, and tool marks.

Sourcing & Provenance

Linking sedimentary materials to quarries and landscapes using macroscopic traits and lab methods.

Conservation Notes

Basic care considerations for sedimentary stone artifacts and architecture: salts, moisture, and cleaning risks.
