ARCHAEOLOGY, TOOLS, METHODS AND ANALYSIS
This task of interpretation has five main aspects. The first concern is the accurate and exact description of all the artifacts concerned. Classification and description are essential to all archaeological work, and, as in botany and zoology , the first requirement is a good and objective taxonomy.

Taking the necessary measures to maintain employees’ safety, we continue to operate and accept samples for analysis. History, anthropology, and archaeology are three distinct but closely related bodies of knowledge that tell man of his present by virtue of his past. Historians can tell what cultures thrived in different regions and when they disintegrated. Archaeologists, on the other hand, provide proof of authenticity of a certain artifact or debunk historical or anthropological findings.
Studying the material remains of past human life and activities may not seem important or exciting to the average Joe unlike the biological sciences. It is in knowing what made past cultures cease to exist that could provide the key in making sure that history does not repeat itself. Over the years, archaeology has uncovered information about past cultures that would have been left unknown had it not been with the help of such technologies as radiocarbon dating, dendrochronology , archaeomagnetic dating, fluoride dating, luminescence dating, and obsidian hydration analysis, among others.
Radiocarbon dating has been around for more than 50 years and has revolutionized archaeology. Carbon 14 dating remains to be a powerful, dependable and widely applicable technique that is invaluable to archaeologists and other scientists. The unstable and radioactive carbon 14, called radiocarbon, is a naturally occurring isotope of the element carbon. When a living thing dies, it stops interacting with the biosphere, and the carbon 14 in it remains unaffected by the biosphere but will naturally undergo decay.
Decay of carbon 14 takes thousands of years, and it is this wonder of nature that forms the basis of radiocarbon dating and made this carbon 14 analysis a powerful tool in revealing the past. The process of radiocarbon dating starts with the analysis of the carbon 14 left in a sample.
Chronology of rock art, ranging from Paleolithic to present times, is a key aspect of the archaeology of art and one of the most controversial. It was based for decades in nonscientific methods that used stylistic analysis of imagery to establish one-way evolutionary schemes. Application of scientific methods, also called absolute dating, started to be used in the s and since then has increased more and more its significance, as judged by the large number of papers published in the last two decades on this subject Rowe
Excavation is the archaeologist’s main method of It is used to slowly scrape away the dirt of a site Instead they should wrap it in tinfoil and send it off for a carbon dating test.
Engaged Archaeology. The first step in an archaeological excavation is surveying the area. This can be done either with remote sensing or direct visual observation. Archaeologists conducting a survey. Archaeologists also use non-invasive techniques to survey sites known as remote sensing. There are many methods including aerial photography which is simply taking pictures from an airplane, hot air balloon or even a remote controlled drone; ground penetrating radar which is used to locate artifacts hidden below ground, and LIDAR, which uses lasers to scan the surface from the air through vegetation.

They start by setting up a grid and connecting the grid to a datum. A datum is a fixed reference point, often one placed by the U. A USGS datum. The next step is to dig several test pits.
Test pits are a small hole dug to determine the location, density and spread of artifacts.

Underwater archaeological excavation is very similar to traditional land archaeology. We use similar tools but usually the plastic version of the tool so that it does not fall apart in the salt water. The archaeological goal of excavating materials in a controlled fashion where the original location of each object or artifact can be recorded and analyzed later is the same wherever you dig. The methods employed as we work underwater are slightly different because of the environment and the need for some different tools.
Archaeology is the study of ancient artifacts, whether they be material remains (e.g., Once an excavation has begun the findings may not accord with what we consider to stand out, and gets the team used to working together in a sometimes difficult climate. Organic remains are later tested using C14 dating methods.
What is Archaeology? The study of the human past through material evidence of humansthe archaeological record. Archaeologists attempt to reconstruct and interpret the cultural change and variation of the human past. Objects alone do not help us much When things are found in context, in their original setting, we gain a much more information. Context, means where an artifact is found. Not just the place, but the soil, the site type, the layer the artifact came from, what else was in that layer.
Archaeologist conduct field work to find material remains in context. Once an object is in the museum it is much harder to understand the context. Why do archaeologists dislike the art market? Art markets encourage looting. Looting destroys context. Many of the objects in the art world come from looting.
Archaeological Dating: Stratigraphy and Seriation
When museums and collectors purchase archaeological items for their collections they enter an expensive and potentially deceptive commercial fine arts arena. Healthy profits are to be made from illicitly plundered ancient sites or selling skillfully made forgeries. Archaeology dating techniques can assure buyers that their item is not a fake by providing scientific reassurance of the artefact’s likely age.
Archaeological scientists have two primary ways of telling the age of artefacts and the sites from which they came: relative dating and absolute dating. Relative Dating In Archaeology Relative dating in archaeology presumes the age of an artefact in relation and by comparison, to other objects found in its vicinity. Limits to relative dating are that it cannot provide an accurate year or a specific date of use.
Archaeological method that their history of archaeology is a site. Although not that archaeologists are procedures used dating techniques to choose from.
Chronological dating , or simply dating , is the process of attributing to an object or event a date in the past, allowing such object or event to be located in a previously established chronology. This usually requires what is commonly known as a “dating method”. Several dating methods exist, depending on different criteria and techniques, and some very well known examples of disciplines using such techniques are, for example, history , archaeology , geology , paleontology , astronomy and even forensic science , since in the latter it is sometimes necessary to investigate the moment in the past during which the death of a cadaver occurred.
Other markers can help place an artifact or event in a chronology, such as nearby writings and stratigraphic markers. Dating methods are most commonly classified following two criteria: relative dating and absolute dating. Relative dating methods are unable to determine the absolute age of an object or event, but can determine the impossibility of a particular event happening before or after another event of which the absolute date is well known.
In this relative dating method, Latin terms ante quem and post quem are usually used to indicate both the most recent and the oldest possible moments when an event occurred or an artifact was left in a stratum , respectively. But this method is also useful in many other disciplines. Historians, for example, know that Shakespeare’s play Henry V was not written before because Shakespeare’s primary source for writing his play was the second edition of Raphael Holinshed ‘s Chronicles , not published until That means that the play was without fail written after in Latin, post The same inductive mechanism is applied in archaeology, geology and paleontology, by many ways.
For example, in a stratum presenting difficulties or ambiguities to absolute dating, paleopalynology can be used as a relative referent by means of the study of the pollens found in the stratum. This is admitted because of the simple reason that some botanical species, whether extinct or not, are well known as belonging to a determined position in the scale of time.

Excavation is the most time-honored archaeological tool for understanding the processes of the human past, and it certainly represents the type of activity that most people attribute to archaeology. As a definition, excavation is simply the controlled exploration of what lies below the surface, usually carried out systematically in gridded trenches with shovel and trowel.
It is often slow and tedious work which involves digging down a centimeter at a time, but can also be backbreaking, difficult toil, shoveling through meters of densely packed soil. But the purpose is the same in either case, to reveal the types of human activities that took place at a site over time. Through the process of excavation, archaeologists look backwards into time, examining an area at discrete temporal periods.
Excavating a few centimeters down may reflect the material culture of the s while several meters may uncover artifacts from ancient times. Researchers can use the incomplete material record to reconstruct the cultural history of the place at particular points in time. The visible remains of the ancient past do not normally lie exposed on hilltops or in the open desert.
The Parthenon in Athens and the Egyptian pyramids are the exceptions and not the norm Figure 8. More commonly, archaeological sites are buried beneath the surface and may be partially or totally invisible to the eye. How then do archaeologists even locate sites given such a situation?
