Summary	Munsell soil color recording is the standard method for describing the color of soils, sediments, and artifacts in archaeology and geoarchaeology using Albert Munsell's perceptually ordered color system. Rather than relying on subjective names like 'brown' or 'tan,' the analyst matches a sample to printed color chips and records a three-part notation — hue, value, and chroma — that fixes the color as a point in a standardized three-dimensional space. This makes color a reproducible, communicable observation that different excavators, sites, and decades can compare directly. Color in turn carries information about organic content, oxidation and reduction, burning, and parent material, so disciplined Munsell recording is a routine first step in distinguishing deposits, defining horizons, and reading site formation.	The Harris matrix is a method for recording and diagramming the stratigraphic sequence of an archaeological site as a partial-order diagram of individually defined contexts. Devised by Edward C. Harris at the Winchester excavations in 1973 and codified in his Principles of Archaeological Stratigraphy, it treats every deposit, cut, and interface as a separate stratigraphic unit and reduces the tangle of physical relationships among them to a minimal directed acyclic graph that expresses only relative temporal order. By distinguishing physical superposition from temporal sequence and stripping away redundant relationships through transitive reduction, the matrix turns the three-dimensional complexity of a dig into a single, auditable diagram. It is the structural backbone of single-context recording and the standard interface between excavation and chronological modeling.	Soil micromorphology is the microscopic study of undisturbed soils and sediments in thin section to reconstruct how archaeological deposits formed and were altered. An oriented block is cut from a deposit without disturbing its internal structure, hardened with resin, and ground into a slice about thirty micrometers thick that can be examined under a petrographic microscope. At that scale the analyst can read features invisible in the field — the arrangement of mineral grains, microscopic charcoal and bone, plastered surfaces, dung, trampling fabrics, and the pedofeatures left by water, roots, and burrowing organisms. Developed for soil science by Walter Kubiëna and adapted for archaeology by geoarchaeologists such as Goldberg, Macphail, and Courty, micromorphology is the highest-resolution tool for interpreting site formation, occupation surfaces, and anthropogenic deposits in their original spatial context.
