Soil Horizons (A,B,C)

A is the upper part of a soil, where active organic and mechanical composition of geological and organic material occurs, B is a layer found below the A horizon where clays accumulate that are transported downward by water. C is below the B horizon that consists of the unaltered or slightly altered parent material.

Temporal Types

A morphological type that has temporal significance, also known as a time-marker or index fossil.

Pattern Recognition

Patterns based on types

Method and theory in American archaeology

Published by Gordon R. Willey and Phillip Phillips. little interpretation had taken place in American archaeology, and their book offered an analytical perspective; the methods they described and the structural framework they used for synthesizing American prehistory were all geared toward interpretation. Method and Theory served as the catalyst and primary reader on the topic for over a decade.

Frontier Pattern vs Carolinian Pattern

Shows the different needs of the Carolinian pattern (more city oriented) vs the frontier pattern (more wild so they needed more arms for protection or grew more tobacco because they had more agricultural land) More tobacco on the frontier because more men were on the frontier and they're the ones who smoked it This is the same as Stanley South → Pattern recognition in historical archaeology/patterns based on types

South India Example

Sir Mortimer Wheeler trained southern Indians to find scores of silver and gold roman coins to date the deposits, since they were originally found without chronology.

Arbitrary level

The basic vertical subdivision of an excavation squre; used only when easily recognizable "natural strata" are lacking or when natural starta are more than 10 centimeters thick

Space-time Systematics

The delineation of patterns in material culture through time and space. These patterns are what the archaeologist will eventually try to explain or account for.

Site Formation

The human and natural actions that work together to create an archaeological site

Culture History

The kind of archaeology practiced mainly in the early to mid twentieth century; it explains differences or changes over time in artifact frequencies by positing the diffusion of ideas between neighboring cultures of the migration of a people who had different mental templates for artifact styles. Outlines human prehistory and historic period, chronology gives a framework for culture history, and gives a scale to measure cultural processes and evolution

Settlement system

Trapped Charge Dating

forms of dating that rely on the fact that electrons become trapped in mineral's crystal lattices as a function of background radiation. The age o the specimen is the total radiation received divided by the annual does of radiation.

Nicolas Steno

formulated the law of superposition

Homo erectus dating issue

found infant homo erectus fossils very far away. They found the bones to be 2 million years old, which they could not believe because they thought they only lived in Africa. Argon-Argon dating showed it was 1.8 million years old.

Stratigraphic Area Excavation

identification of the context is important , Wheeler emphasized stratigraphy - never dig around the building because it destroys the stratigraphic layers and chronological record

The personality of Britain

if you look at the natural deposits you find a major division in the land of Scotland and England; looked at settlement pattern throughout British history; low land-fertile agricultural regions, region of invasion and colonization, and transformation vs high land zone - mountain and hill region, region of cultural survival, and traditional zone

Why is temporal dimension important and first step?

important to know the timing of when something happened. Helps establish a chronology; without a chronology we would not be able to date things. "Culture history" approach has outlined human prehistory and historic periods for most areas on earth

Henry Miller

lead in archaeological excavation of St. Mary's city, Analyzed the layout of St. Mary's citym, and foudn it to be an example of baroque planning, rather than an unorganized layout. shows that "tidewater towns" were unplanned and unsophisticated, and that such cities were meant to be centers of political power, rather than centers of commerce.

Culture area

marked by a particular set of material traits (environment and culture)

Maya Urban Site

palaces, house mounds, tikal settlement maps, high density and presence of heterogenous populations and centralized political administrativem communicative and religious functions . sites in the lowlands tend to be more compact

Pipe Stem Dating

pipes generally broke within a year of being made. Their shapes, decorations, stem lengths and thickness characterized its time. Systematically date site within years by using a drill set to measure holes of pipe and place them into categories.

Popularity seriation (battleship shaped curves)

shows frequencies as large and then tapering off in the middle

Index fossils (time markers)

strata in widely separated sites containing the same distinctive artifact forms are assumed to be of similar age. Ex. Oscar Montelius divided the Stone, Bronze and Iron Age with distinctive sets of artifacts or artifact styles

Seriation

styles change, and new technologies arise over time. Uses the changes in the frequencies of artifacts or styles to date sites relative to one another

Settlement Pattern

the distribution of archaeological sites across a region.

Law of superposition

the geological principle that in any pile of sedimentary rocks that have been disturbed by folding or overturning, each bed is older thn the layers above and younger than the layers below

Mental Template

the ideas and values that govern the creation of artifacts. Also called "mental templates" or "cognitive maps" or "cognitive frameworks," these structures are not beyond archaeological inference. Recognition of Mentefacts allows archaeologists to explore nonmaterial aspects of culture through analysis of the material manifestations of cultural needs and beliefs. INFERENCE; "in the mind of the maker

Reverse Stratigraphy

the result when sediment is unearthed by human or natural actions and moved elsewhere in such a way that the latest material is deposited on the bottom of the new sediment and progressively earlier material is deposited higher and higher in stratigraphy.

Landscape Archaeology

the study of ancient human modification of the environment

Astro - Archaeology

the study of how people in the past "have understood the phenomena in the sky, how they used phenomena in the sky, and what role the sky played in their cultures., Much of Chaco canyon is built in conjunction with important solar and lunar directions. also the presence of the sun dagger, where explicit light markings that record all the key events of both the solar and lunar cycles: summer solstice, winter solstice, equinox, and the major and minor lunar standstills of the moon's 18.6 year cycle

Typology

Relative Dating

unspecific segments of time, expressed as relationships or comparisons

Time markers

use distinctive artifact forms to characterize and correlate strata between archaeological sites

Santa Catalina de Guale (David H Thomas)

used flotation to recover, had to use conservation excavation strategy - only excavate as much as you need to

Cross-Dating

using other objects to find the date of the artifact

Alta Toquima

village located 11,000 feet in the mountains of central Nevada, used a shifter that was a shaker screen mounted on two pivoting legs to recover artifacts, Before survey and excavations conducted at Alta Toquima by Dr. Thomas and his team, many archaeologists believed that early American hunters avoided high altitude environments as too harsh and barren to sustain life. However, mountains were used intermittently by small groups of hunters who seasonally exploited mountain sheep. These new large, long-term settlements at Alta Toquima represented a major shift in how ancient Americans used mountain resources, and illustrate how archaeological research continues to teach us about the past.

Gordon R Wiley

was attempting to put to work ideas about identifying not just archaeological sites, but how sites fit into the context of a physical landscape, available resources, and other sites in the region

Spatial Dimension

where it is is important
