Why Is Geophysical Survey Important To Excavation?

1887 Words8 Pages

Geophysical survey is arguably an essential part of planning an archaeological excavation. It acts as a guide to archaeologists, showing them areas of interest in the landscape that would be worth excavating, that would otherwise be impossible to detect. It could also help archaeologists decide which areas of a site would be best to excavate, and whether or not the site would be worth excavating in the first place. Planning applications are important in preparing to excavate a site, as without them, the excavation cannot take place. Geophysics can help when it comes to making considerations for planning permission, as it can help determine many factors that would need to go into the aforementioned planning permission, such as how much of the …show more content…

Geophysics can determine changes in the physical property of a piece of land, showing us areas of archaeological interest, which might not be visible using only an aerial map of the landscape (Geophysics & Remote Sensing 2014: 60). Geophysics is a fairly fast method of surveying (Geophysics & Remote Sensing 2014: 61), which also helps when planning applications need to be completed quickly in order for excavations to begin on …show more content…

GPR is a time consuming method of geophysical surveying (Geophysics Techniques n.d.), but it is detailed, and also allows for three dimensional maps of an area of potential archaeological interest to be produced, showing the depth of an area, and at what depth the archaeological features can be found (Renfrew and Bahn 2012: 98). Like ground resistivity surveys, this method of geophysics can be used in more urbanised areas with great effect (Geophysics Techniques n.d.), making it a more useful method of geophysical survey than magnetic surveys for more urbanised

An assessment of the cultural value of the site and its significance in Burra Charter terms. • Aesthetic Value: The Landscape of Mount William quarry is surrounded by ranges such as Macedon Range, Dandenong Ranges and Great Diving Range, and standing on the top of the Mount William quarry will able to see the range and the valley. It also home to restricted pocket of original vegetation in modern day along the edge of ridge. • Historic Value: Mount William Stone Axe Quarry is one of the most importance, largest and intensively worked quarries in Australia, with more than 260 mining pits and many mounds of waste rock and flaking floor scatters across the site surrounding the work station. • Scientific Value: Diabase (greenstone) is suitable to aboriginal lifestyle with tool is a raw material which is product of an age of volcanic activity, tough, fine-grained basalt and shock-resistance so it won’t shattered when impact.

Using coordinates or simple objectives allows the ability to make proper determination. Geographic data allows identifiable information to be offered to subscribers with the encouragement of geographical indicators. Display tools offer a realism of visual effects and the most applicable advantages. Photogrammetry and Remote Sensing, spatial statics and Geographic Information Systems (GIS): Systems of these nature offer geographers collaborative and analyzed information far more unique than traditional research techniques (Geographic Information Systems as an Integrating Technology: Context, Concepts, and Definitions,2015). Lastly, geographic reality and space relation must be gathered using input and output of data and formulaic sequences, but the tools make them applicable to user.

Science DBQ The rock cycle is important to scientists in many ways. It shows the top three rocks and shows how they form. Geography is the study of rocks and minerals (Doc 1.) .Physical geology is the study of how rocks form into other rocks and the composition of rocks and landforms (OI), so physical geology scientists probably use the rock cycle everyday in their work.

There are many explorations taken in the Grand Canyon trying to learn to learn more about the earth’s crust and how it is formed. In Timothy Egan and Casey Egan’s article they give evidence that science is helping us to understand the age of the earth, “The rock floor is around 1.8 billion years old. At the rim, the Kailbab formation is 270 million years old”(Timothy Egan and Casey Egan). Many scientists also go to parks like Yellowstone National Park and Yosemite National Park to study wildlife and different plant species. “Whether this park would continue to be a living thing, with its nearly 750 plant species, was perhaps out of our control”(Timothy Egan and Casey Egan).

1. How does the discipline of geography provide a bridge between the social sciences and the physical science? Geography can be described as the most interdisciplinary of disciplines. Geography is the study of our planet 's landscapes, peoples, places and environments, global issues, the human impact on the environment and also, the interconnectedness of the world and our communities within it. Human geography takes into account the dynamics of cultures, societies, and economies, and physical geography studies the physical landscapes and the environment.

He claims that the physical geographer has hurt their field by only including the most basic principles of geology. What Mackinder really believes is that a geologist looks at the present to interpret the past, while a physical geographer looks at the past to interpret the present.

Geography is the study of the world and its culture, region, atmosphere and climate. We can study many things through geography and cartography. Maps not only show us the layout of countries and oceans but also climate, precipitation, terrane and population. Geography not only encompasses physical features but also human and environmental features. Human geography illustrates how and where people live.

Positivism in physical geography is applied through a number of steps: establish research problem, establishing data sources: primary and secondary sources, selecting samples: random and not-random and methods of analysis: statistical techniques. In physical geography the positivistic approach is normally applied through the scientific method, but this is not the only way in which the positivistic approach is applied. There is also an aspect of realism to the positivistic approach as geographers need to assume there is an external reality that is capable of being examined. A careful measurement should be taken as measurement often alters measured entity. Through positivism physical geographers use reductionalism, which is done by only picking a representation of variables to observe and measure.
