Abraded: A method of making rock images by lightly rubbing the rock surface with a
coarse, durable stone tool; a shallower effect than cupule.
Abstract motif: Any rock art image of a kind too abstruse, not easily understood, or so
stylized as to be unrecognizable as a real object or living thing. A non-figurative motif not recognizable as an object of the real world.
Alluvial: Of, pertaining to, or composed of sediment deposited by flowing water.
Carbon-14) which directly measures the amount of 14C in a sample; because
microscopic traces can be dated, AMS is used on rock imagery to date both
organic binders in pictographs and microbial residues in rock varnish.
Animism: Any belief system whereby natural phenomena and things—both animate
and inanimate—are held to possess an innate soul.
Anthropic: Pertaining to human form.
Anthropocentric: Relating to imagery that predominatly depicts humanlike figures.
Anthropologist: Anthrologists are people that practice anthropology, which is the study of humanity. Basically they want to figure out what makes humans human. An anthropologist might be interested in everything from the traditions of a tribe on a remote island to the culture of an urban community and everything in between.
Anthropology: The study of humanity, attempting to establish what defines Homo Sapiens, who our ancestors are, what our physical traits are, how we behave, why there are variations among different groups of humans, and how the evolutionary past of Homo Sapiens has influenced its social organization and culture.
Anthropomorph: Any rock art element of human-like form, stylized or realistic.
Anthropomorph: Any rock art element of human-like form, stylized or realistic.
Archaeological Site:
Archaeology: The scientific study of ancient cultures and their life and activities through the examination of their material remains such as fossil relics, artifacts, tools, and other artifacts usually dug up from the ground. Archaeology The scientific study and reconstruction of the human past through the systematic recovery of the physical remains of man's life and cultures. Artifacts, structures, settlements, materials, and features of prehistoric or ancient peoples are surveyed and / or excavated to uncover history in times before written records. Archaeology also supplements the study of recorded history. From the end of the 18th century onward, archaeology has come to mean the branch of learning which studies the material remains of man's past. Its scope is, therefore, enormous, ranging from the first stone tools made and fashioned by man over 3 million years ago in Africa, to the garbage thrown into our trash cans and taken to city dumps and incinerators yesterday. The objectives of archaeology are to construct cultural history by ordering and describing the events of the past, study cultural process to explain the meaning of those events and what underlies and conditions human behavior, and reconstruct past life-ways. Among the specialties in the field are: archaeobiology, archaeobotany, archaeozoology, and social archaeology. Modern archaeology, often considered a sub-discipline of anthropology, has become increasingly scientific and relies on a wide variety of experts such as biologists, geologists, physicists, sociologists, anthropologists, and historians. The methods appropriate to different periods vary, leading to specialized branches of the subject, e.g. classical, medieval, industrial, etc., archaeology.
Archaeoastronomy: The study of ancient cultures’ knowledge of, and use of astronomy; such knowledge may be incorporated in rock imagery. Also known as “Astroarchaeology.”
Archaic period: 7,000 BC is known as the Archaic Period, a time in which people, known as hunter-gathers, built basic shelters and made stone weapons and stone tools. The early Desert Archaic peoples, like their Paleo-Indian predecessors, traveled in small mobile groups, probably extended families, in a ceaseless quest for food, materials, fuel and water. They carried their belonging on their backs, which prevented the accumulation of material wealth and, probably, the development of marked social status.
Atlatl: A weapon used for hunting that propelled darts or small spears. It was later replaced by the bow and arrow around 500 A.D. The Atlatl is often depicted as a circle with a line through it.

~ C ~
Cairn: An anthropic mound of stones.Carbon dating: Also known as the Carbon 14 method and radio-metric dating. A scientific technique for determining when organic remains such as charcoal, bone, shell, and plant material died. Organic matter contains radioactive carbon-14 isotopes, which decay over time at a known rate. Carbon dating measures the remaining volume of carbon-14 isotopes in matter, providing an approximate age since death. Although often pigments used in rock painting contained an organic binder such as blood, there is usually too little pigment remaining on the rock to make direct dating possible.
Carbon ratio dating: A method of dating in archaeology and earth science that can be used to derive or estimate the age of soil and sediment samples up to 35,000 years old. The method is experimental, and it is not as widely used in archaeology as other chronometric methods such as radiocarbon dating. The methodology was introduced by Archaeology Consulting Team from Essex Junction in 1992.
Chert: A collective term for sedimentary microcrystalline silica rock formed by selective replacement of limestone; in some regions occurring as flint.

Clast: A fragment of rock of any size, but used especially to denote cobble-sized angular breakdown debris.; synonymous to detritus.
Concretion: A coalesced deposit of mineral matter formed through the deposition of a cementing mineral precipitate, such as carbonate, silica or iron salts.
Cupule: A cup shaped depression in the surface produced by grinding, pecking or a combination of both. They are also referred to as “pit-and-groove.” These cup-like depressions or pits in boulders are thought to be the oldest form of rock art, first appearing in parts of the Great Basin 7000 years ago.
Curvilinear: An element or motif consisting of curved lines.
~ D ~
| Desert varnish: Desert varnish, also called Patina, is a thin, dark red to black mineral coating (generally iron and manganese oxides and silica) deposited on the surface of pebbles and rocks of desert regions. As dew and soil moisture brought to the surface by capillarity evaporate, their dissolved minerals are deposited on the surface. The rate of varnish formation varies: it generally is thought to take about 2,000 years for it to form in arid areas, because it coats artifacts and natural objects known to be of such antiquity; but it has formed in less than 50 years in the Mojave Desert. Both high evaporation rates and sufficient precipitation are necessary for desert varnish formation. |
